    BARRON, Chief Judge.         Maine allows for direct popular
    participation     in     the   state's   lawmaking   process    through    two
    distinct means:        a "people's veto," as it is commonly known, and
    a "direct initiative."         Me. Const. art. IV, pt. 3, §§ 17-18.            To
    place either type of measure on the state ballot, a "written
    petition" that contains a minimum number of signatures from those
    who are "qualified to vote for Governor" in Maine must be filed
    with the Secretary of State of Maine.           Id. § 20.
    Maine law refers to a person who "solicits signatures
    for the petition by presenting the petition to the voter, asking
    the voter to sign the petition and personally witnessing the voter
    affixing the voter's signature to the petition" as a "circulator."
    Me. Stat. tit. 21-A, § 903-A.        Maine law further provides that the
    "circulator" must be a Maine resident who is also registered to
    vote in Maine.     Id.
    This appeal arises from a suit that challenges both the
    residency   and   the     voter-registration    requirements.      The    suit
    alleges   that    each    requirement,    by   restricting   who   may    be    a
    circulator, violates the First Amendment to the United States
    Constitution as incorporated against the states by the Due Process
    Clause of the Fourteenth Amendment.            See Grosjean v. Am. Press
    Co., 
    297 U.S. 233
    , 245 (1936).

    The suit was brought in 2020 in the United States
    District       Court       for    the    District   of     Maine     by    a     nonprofit
    organization,          a    political      action   committee,       a     Maine    State
    Representative, and a professional collector of signatures for
    petitions who resides in Michigan.                  The plaintiffs named as the
    defendants the Secretary of State of Maine in his official capacity
    and the Deputy Secretary of State of Maine for the Bureau of
    Corporations in hers.
    On the same day that the plaintiffs filed their suit,
    they    also    moved       for   a     temporary   restraining      order       and/or   a
    preliminary injunction to prevent the residency requirement and
    the    voter-registration             requirement   from     being   enforced.         The
    District Court denied the request for the temporary restraining
    order    but    ultimately        granted     the   motion    for    the       preliminary
    injunction.       The defendants now appeal from that latter ruling.
    We affirm.
    I.
    A.
    The portions of the Maine Constitution that pertain to
    the "people's veto" provide that "[t]he effect of any Act, bill,
    resolve or resolution or part or parts thereof" that the Maine
    Legislature passes "shall be suspended upon the filing" of a
    "written petition," and that the measure thereafter must be "voted
    - 4 -
    on by the people."     Me. Const. art. IV, pt. 3, § 17 (emphasis
    added); see also Me. Senate v. Sec'y of State, 
    183 A.3d 749
    , 753
    (Me. 2018) (describing the "people's veto").     The portions of the
    Maine Constitution that pertain to "direct initiative[s]" state
    that "[t]he electors may propose to the Legislature for its
    consideration any bill, resolve or resolution," though "not an
    amendment of the State Constitution, by written petition."          Me.
    Const. art. IV, pt. 3, § 18(1) (emphasis added).      These provisions
    also state that, unless the proposed direct initiative is "enacted
    without change by the Legislature," it must be "submitted to the
    electors   together   with   any   amended    form,   substitute,    or
    recommendation of the Legislature," who then may "choose between
    the competing measures or reject both."      Id. § 18(2).
    Under the Maine Constitution, the "written petition"
    referred to in the provisions quoted above must contain a specified
    number of valid signatures of eligible Maine voters and be filed
    with the Maine Secretary of State ("the Secretary").        The total
    number of signatures "shall not be less than 10% of the total vote
    for Governor cast     in the last gubernatorial election."          Id.
    §§ 17(1), 18(2).
    The Maine Constitution defines a "circulator" as "a
    person who solicits signatures for written petitions."      Id. § 20.
    It states that a circulator "must be a resident of [Maine] and
    - 5 -
    whose name must appear on the voting list of the city, town or
    plantation of the circulator's residence as qualified to vote for
    Governor."      Id.   A Maine statute provides that the "written
    petition" referenced in these provisions of the Maine Constitution
    "may be circulated by any Maine resident who is a registered voter
    acting as a circulator of" such a petition.   Me. Stat. tit. 21-A,
    § 903-A.
    At the time that the written petition is filed with the
    Secretary, the circulator "must sign the petition." Id. § 902.
    The circulator also must "verify by oath or affirmation" that she
    "personally witnessed all of the signatures" collected "and that
    to the best of the circulator's knowledge and belief each signature
    is the signature of the person whose name it purports to be."   Id.
    The circulator must file alongside the written petition
    an executed affidavit that includes "[t]he circulator's printed
    name, the physical address at which the circulator resides and the
    date the circulator signed the affidavit."      Id. § 903-A(4)(A).
    The affidavit must include attestations that "the circulator was
    a resident of [Maine] and a registered voter in [Maine] at the
    time of circulating the petition."     Id. § 903-A(4)(C).   If the
    circulator "[k]nowingly fails to truthfully execute and timely
    file" an affidavit, that individual "commits a Class E crime."
    Id. § 904(6).
    - 6 -
    The   Secretary   must    "determine    the   validity   of    the
    petition . . . within 30 days from the date" that the petition is
    filed with her.     Id. § 905(1).       In undertaking that review, the
    Secretary   may    invalidate   signatures       that   are   obtained    from
    individuals who are not residents of Maine or that are collected
    by circulators who were not in compliance with the residency and
    voter-registration requirements.             See, e.g., Hart v. Sec'y of
    State, 
    715 A.2d 165
    , 166 (Me. 1998); Jones v. Sec'y of State, 
    238 A.3d 982
    , 985 (Me. 2020).
    Additional provisions of the Maine Constitution concern
    the duration of the petition circulation process.             See Me. Const.
    art. IV, pt. 3, §§ 17(1), 18(1).           They require that the requisite
    number of signatures for a written petition must be secured within
    a specified period after the circulation process begins for a
    direct initiative petition, and after the legislative session at
    which the challenged action occurred for a people's veto petition.
    Id.
    B.
    Except where noted otherwise, the following facts are
    not in dispute in this appeal.             In 2019, the We the People PAC
    ("We the People"), a political action committee registered in the
    State of Maine, and state Representative Billy Bob Faulkingham,
    who represents the 136th district in the Maine State House of
    - 7 -
    Representatives and is a member of We the People, sought to
    sponsor, and also circulated a petition in support of, a direct
    initiative entitled, "An Act to Clarify the Eligibility of Voters."
    The   proposed   direct   initiative   sought   to   "force   the   state
    legislature to adopt verbatim [a] proposed ban on all non-citizen
    voting in the State of Maine or place the question on the next
    general election ballot . . . to be decided by the voters of
    Maine."1
    For the initiative to be placed on the ballot, the
    Secretary first must "furnish[]" or "approve[]" a "form[]" that is
    then circulated for signatures by qualified voters.           Me. Const.
    art. IV, pt. 3, § 20.     This form, once approved, is the "written
    petition."     See id.
    Maine law provides, however, that "the written petition"
    for a direct initiative "may not be filed in the office of the
    Secretary of State later than 18 months after the date the petition
    form was furnished or approved by the Secretary of State."            Id.
    § 18(1).     Maine law further provides that only those signatures
    collected within the year leading up to the date on which the
    1Maine law already limits the franchise in state and
    local elections to United States citizens who are or will be at
    least eighteen years of age at the time of the upcoming general
    election. Me. Const. art. II, § 1; Me. Stat. tit. 21-A, §§ 111(1),
    111-A. The proposed initiative would have "amend[ed] the voter
    qualification statute to emphasize" these requirements to be a
    voter "in an election in a municipality."
    - 8 -
    petition is filed with the Secretary count as valid.                   See Id.
    § 18(2) ("A signature is not valid if it is dated more than one
    year prior to the date that the petition was filed in the office
    of the Secretary of State.").           Moreover, Maine law provides that
    the signed petition must be filed with municipal authorities or
    state   election    officials    "for    determination      of    whether    the"
    signatures are of "qualified voters" by the tenth day before the
    signed petition is filed with the Secretary.              Id. § 20.
    In light of these provisions, the proponents, to have
    placed their proposed direct initiative on the November 2020 ballot
    would have to have filed their signed petition with the Secretary
    by February 3, 2020       (and for municipal        or election official
    certification ten days before that); to have placed their proposed
    direct initiative on the November 2021 ballot, the proponents would
    have to have filed their signed petition with the Secretary by
    January    21,   2021   (and    for     municipal   or    election    official
    certification ten days before that); and to have placed their
    proposed   direct   initiative    on     the   November    2022    ballot,    the
    proponents would have to have filed their signed petition with the
    Secretary by February 26, 2021 (and for municipal or election
    official certification ten days before that).             See id. §§ 18, 20.
    To file a petition after February 26, 2021, its supporters would
    have had to apply to the Secretary for a new petition form, which,
    - 9 -
    once approved, would have restarted their eighteen-month approval
    clock.   See id. § 20.    They then could have collected signatures
    on that form and would have had to have filed a signed petition by
    January 31, 2022 for placement of a proposed direct initiative on
    that same November 2022 ballot.
    Having   obtained    their     approved     petition     form    on
    August 26, 2019, the supporters of the initiative could begin
    gathering signatures.     They claimed in an interrogatory response
    that they used only circulators who were Maine residents.                  The
    petition for the initiative would have needed a minimum of 63,067
    signatures to have been placed on the November 2020, 2021, or 2022
    ballots, given the number of votes cast in the prior gubernatorial
    election, which was held in 2018.       See id. § 18(2).
    By October 16, 2019, only 2,000 people had signed the
    petition after it had been approved for circulation nearly two
    months before. The campaign to collect signatures then lay dormant
    for the following year.
    The   plaintiffs    resumed    the    petition   drive   in     mid-
    October 2020,   this time with the aid of not only Maine residents
    but also out-of-state residents who assisted in the process of
    securing signatures for the petition.          The out-of-state residents
    worked with in-state "witnesses" but did not themselves purport to
    - 10 -
    serve as circulators.               Between mid-October 2020 and late January
    2021, 38,000 signatures for the petition were collected.
    C.
    The        plaintiffs       are      We     the    People,       Representative
    Faulkingham,          and    the     Liberty        Initiative       Fund,     a     nonprofit
    organization       that       has    been     involved        in   petition        circulation
    efforts,     including         the     petition        circulated       for        the   direct
    initiative       at    issue        here,   as   well     as       Nicholas    Kowalski,       a
    professional collector of signatures for petitions who resides in
    Michigan.       The plaintiffs filed suit in the United States District
    Court for the District of Maine on December 31, 2020.                               They named
    as defendants then-Secretary of State Matthew Dunlap and Deputy
    Secretary of State for the Bureau of Corporations, Elections and
    Commissioners Julie Flynn, in their official capacities.2
    The plaintiffs brought claims under state and federal
    law,   including            under     the   First       Amendment       to     the       federal
    Constitution,         that     challenged        both    the       residency       and    voter-
    registration requirements to be a circulator.3                         The same day that
    On February 23, 2021, Dunlap was substituted by Shenna
    2
    Bellows, the current Secretary of State of Maine.
    3    The plaintiffs' complaint also challenged other
    provisions       of  Maine  law  that  impose  certain disclosure
    - 11 -
    the plaintiffs filed their suit, they also moved for a temporary
    restraining order and/or a preliminary injunction.                  The plaintiffs
    in   so   moving      requested   that   the   District     Court    enjoin     the
    defendants      from    enforcing   Maine      Revised   Statutes     title 21-A,
    § 903-A, "to the extent it requires that petitions for a direct
    initiative or people's veto may only be circulated by a registered
    voter of Maine" and "may only be circulated by a resident of the
    State of Maine, as applied to out-of-state circulators who first
    submit    to    the    jurisdiction      of   the   State   of   Maine    for   any
    investigation and/or prosecution of alleged violations of Maine's
    election code with respect to" direct initiative or people's veto
    petitions.
    The District Court denied the plaintiffs' application
    for a temporary restraining order on January 11, 2021.                          The
    District Court concluded that "[e]ven though the plaintiffs raised
    serious legal issues, because the caselaw in this area is nuanced,
    because the plaintiffs failed to provide a sufficient uncontested
    factual record, and because the plaintiffs delayed bringing this
    lawsuit, they failed to sustain their burden to demonstrate that
    requirements on circulators and proponents of direct initiative
    and people's veto petitions. Those requirements are not before us
    because the plaintiffs did not request that they be preliminarily
    enjoined in their motion for a temporary restraining order and/or
    preliminary injunction.
    - 12 -
    they [were] likely to succeed on the merits of th[e] claim."                   We
    the People PAC v. Bellows, 
    512 F. Supp. 3d 74
    , 77 (D. Me. 2021).
    Then, on February 16, 2021 -- the day by which the
    plaintiffs   were      required    to   submit   their    petition    to    local
    officials to have their proposed direct initiative placed on the
    November 2022 general election ballot -- the District Court ruled
    on the motion for the preliminary injunction.               See We the People
    PAC v. Bellows, 
    519 F. Supp. 3d 13
    , 44 (D. Me. 2021).              The District
    Court noted that, in light of the defendants' argument that the
    declarations that the plaintiffs had submitted in support of their
    motion for a preliminary injunction lacked foundation, it would
    "disregard[]     any    portions    [of    the   declarations]       that    lack
    foundation or consist of improper opinion."              
    Id.
     at 17 n.2.      But,
    the District Court denied the defendants' additional objection to
    the plaintiffs' responses to the defendants' interrogatories that
    had been requested as part of the briefing on the motion for a
    preliminary injunction.       
    Id.
    The defendants' objection rested on the contention that
    the plaintiffs' responses to the interrogatories were "extremely
    problematic" because they were "not attributed to particular"
    individuals, were "not sworn," were "filled with hearsay and
    argument," and were "not even signed by" every plaintiff.                     
    Id.
    The   District   Court    explained,      however,   that    the   plaintiffs'
    - 13 -
    responses to the interrogatories had been signed by Representative
    Faulkingham and by Liberty Initiative Fund's president, on behalf
    of Liberty Initiative Fund, as well as by the plaintiffs' counsel.
    
    Id.
         The District Court then added that there is "no requirement
    that the interrogatory responses be signed by all the [p]laintiffs"
    and that the plaintiffs had "represented" in response to an earlier
    order    of       the   District   Court    that   they    "w[ould]    file    sworn
    interrogatory responses, curing the oath defect 'no later than
    February 20, 2021.'"          
    Id.
     (record citation omitted).          The District
    Court then ruled, "[b]ased on the [p]laintiffs' representation,"
    that     it   "consider[ed]        the     [p]laintiffs'     responses    to    the
    [d]efendants' interrogatories as sworn."              Id.4
    Having made those rulings, the District Court assessed
    whether the plaintiffs had met their burden with respect to the
    The plaintiffs filed a sworn version of their
    4
    interrogatory responses on February 19, 2021.      The defendants
    nonetheless contend on appeal that the "sworn version of
    [p]laintiffs' interrogatories" "still exhibited one of the flaws
    identified by the Secretary, and one not addressed by the district
    court: they were not attributed to particular [p]laintiffs." But,
    Liberty Initiative Fund, as well as Representative Faulkingham, on
    behalf of himself and We the People, each separately signed and
    attested to "knowledge, information, and belief" concerning all of
    the plaintiffs' responses to the interrogatories.        Moreover,
    Kowalski signed and attested to his knowledge concerning the
    plaintiffs' response to "Interrogatory #16, the only interrogatory
    response which requires [his] verification." We also see no basis
    for crediting the defendants' conclusory assertion in their
    briefing to us that "[n]ot every [p]laintiff can swear to the
    entire contents of [p]laintiffs' wide-ranging interrogatory
    responses." Thus, we consider the interrogatory responses here.
    - 14 -
    four factors that must be weighed to determine whether to grant a
    motion for a preliminary injunction. See id. at 37. Those factors
    include:
    the movant's likelihood of success on the
    merits; whether and to what extent the movant
    will suffer irreparable harm in the absence of
    preliminary injunctive relief; the balance of
    relative hardships, that is, the hardship to
    the nonmovant if enjoined as opposed to the
    hardship to the movant if no injunction
    issues; and the effect, if any, that either a
    preliminary injunction or the absence of one
    will have on the public interest.
    Ryan v. U.S. Immigr. & Customs Enf't, 
    974 F.3d 9
    , 18 (1st Cir.
    2020).   The District Court ruled that, with the benefit of "a more
    substantial record including affidavits and declarations, as well
    as   interrogatories   and    statements    of   facts,"      preliminary
    injunctive relief was appropriate.       See We the People PAC, 519 F.
    Supp. 3d at 37, 53.
    The   District   Court   determined   that   the   plaintiffs
    established that they were likely to succeed in showing that the
    residency and voter-registration requirements were each subject to
    strict scrutiny because each requirement imposed a "severe burden"
    on the exercise of the plaintiffs' First Amendment rights.            See
    id. at 39, 41, 46, 50-51.     The District Court further determined
    that the plaintiffs established that they were likely to succeed
    in showing that neither the residency requirement nor the voter-
    registration requirement could survive such scrutiny because the
    - 15 -
    defendants could not show that either requirement was narrowly
    tailored to serve a compelling state interest.                Id. at 46-48, 51.
    The District Court next determined that the plaintiffs
    had demonstrated that they were likely to suffer irreparable harm
    absent a preliminary injunction. It noted that "even if the
    [p]laintiffs d[id] not meet the February 16, 2021 deadline, they"
    would be able to "renew their signature collection efforts to put
    their initiative on the 2022 ballot."                   Id. at 52.       Thus, the
    District Court concluded that "while an injunction might make no
    real difference for the current petition drive, th[e plaintiffs]
    will continue to suffer harm in their next petition drive."                      Id.
    As   to    the   effect    of   any   injunction    on    the    public
    interest, the District Court determined that while "the public has
    strong competing interests on both sides" of the dispute, it "has
    a greater interest in upholding its constitutionally protected
    freedom of speech" than it does in "regulati[ng] . . . referendum
    petitions and in protecting the integrity and grassroots nature of
    the direct initiative and people's veto power."                        Id. at 52.
    Finally, as to the "balance of equities," the District Court
    recognized that the plaintiffs had "contributed to the urgent
    nature   of    the      preliminary     injunction     request"   through      "their
    delay"   in    filing      their   lawsuit,      but   ultimately      found   their
    "constitutional challenge both meritorious and important," such
    - 16 -
    that the "balance of equities weigh[ed] in the [p]laintiffs'
    favor."    Id. at 52-53.
    The District Court issued an order on February 16, 2021,
    that preliminarily enjoined Maine Revised Statutes title 21-A, §
    903-A "to the extent it requires that petitions for a direct
    initiative or people's veto may only be circulated by a registered
    voter of Maine" and "to the extent it requires" that such petitions
    "may only be circulated by a resident of the state of Maine, as
    applied    to   out-of-state       circulators   who   first   submit   to   the
    jurisdiction of the state of Maine for any investigation and/or
    prosecution of alleged violations of Maine's election code with
    respect to Referendum and/or People's Veto petitions filed with"
    the defendants.      Id.   In a separate oral order, the District Court
    stayed the plaintiffs' motion for a permanent injunction.
    The defendants filed an interlocutory appeal of the
    District   Court's    order    issuing     the   preliminary   injunction     on
    February    22,   2021.       We    have   jurisdiction    under

    II.
    Before diving into our analysis, it is first useful to
    review the only two precedents of the Supreme Court of the United
    States   that    address     First    Amendment    challenges     to    a   state's
    restriction on who may act as a "circulator" in the petition
    circulation process for a ballot initiative.                  The two precedents
    are Meyer v. Grant, 
    486 U.S. 414
     (1988), and Buckley v. American
    Constitutional Law Foundation, Inc., 
    525 U.S. 182
     (1999).
    A.
    In     Meyer,     the     Court    addressed   a     First   Amendment
    challenge to a Colorado state law that prohibited the use of paid
    circulators.          
    486 U.S. at 417
    .        The Court found merit to the
    challenge.
    In explaining why, the Court first determined that the
    prohibition implicated the First Amendment because it restricted
    "'core political speech.'"           
    Id. at 422
    .      The Court explained that
    the prohibition did so because "[t]he circulation of an initiative
    petition of necessity involves both the expression of a desire for
    political change and a discussion of the merits of the proposed
    change."        
    Id. at 421
    .     Indeed,    the    Court    elaborated,     "to
    capture . . . signatures, [a circulator] will at least have to
    persuade [potential signatories] that the matter is one deserving
    - 18 -
    of     the   public    scrutiny     and   debate    that    would         attend    its
    consideration by the whole electorate."             
    Id.
    The Court then addressed the nature of the burden on
    core political speech that Colorado's ban on paid circulators
    imposed.      The Court determined that the ban "restrict[ed] [the
    initiative proponents'] political expression in two ways."                           
    Id. at 422
    .      First, such a prohibition "limits the number of voices
    who will convey [the proponents'] message and the hours they can
    speak and, therefore, limits the size of the audience they can
    reach."      
    Id. at 422-23
    .       Second, the prohibition "makes it less
    likely that [proponents] will garner the number of signatures
    necessary to place the matter on the ballot."                  
    Id. at 423
    .            In
    consequence, the Court explained that a ban on paid circulators
    "has the inevitable effect of reducing the total quantum of speech
    on a public issue."        
    Id.
    The Court acknowledged that the plaintiffs in Meyer
    "remain[ed] free to employ other means to disseminate their ideas."
    
    Id. at 424
    .   But,   the    Court   emphasized,      that   fact       did     not
    meaningfully        diminish     the   burdensome     nature      of      the      ban's
    restriction on core political speech, because the "prohibition of
    paid     petition     circulators      restrict[ed]     access       to    the      most
    effective, fundamental, and perhaps economical avenue of political
    discourse, direct one-on-one communication."                   
    Id.
            "The First
    - 19 -
    Amendment," the Court explained, protects the proponents' "right
    not only to advocate their cause but also to select what they
    believe to be the most effective means for so doing."          
    Id.
    Based on this analysis of the burden that the ban imposed
    on core political speech, the Court determined that the ban had to
    survive "exacting scrutiny" to comport with the First Amendment.
    
    Id. at 420
    .   The Court fleshed out the "exacting" nature of that
    scrutiny by observing that, because "the statute trenches upon an
    area in which the importance of First Amendment protections is at
    its zenith," the "burden that Colorado must overcome to justify
    this   criminal   law   is   well-nigh   insurmountable."      
    Id. at 425
    (internal quotation marks omitted).
    The Court then moved on to the question of whether the
    ban could survive such "exacting" scrutiny.        The Court determined
    that the fit between the interests that Colorado had put forth in
    support of its ban and the means that the State had selected to
    further that interest was too loose for the ban to pass that
    "exacting scrutiny."     
    Id. at 425-28
    .
    Colorado asserted two interests: first, an "interest in
    making sure that an initiative has sufficient grass roots support
    to be placed on the ballot," and second, an "interest in protecting
    the integrity of the initiative process."        
    Id. at 425
    .    The Court
    dispatched with the asserted interest in ensuring "grass roots
    - 20 -
    support"     by    explaining             that    this    interest          was    "adequately
    protected by [Colorado's] requirement that no initiative proposal
    may   be   placed       on    the    ballot       unless       the    required      number       of
    signatures has been obtained."                    
    Id. at 425-26
    .        It then addressed
    the   interest     in    "protecting             the   integrity       of    the    initiative
    process."    
    Id. at 426
    .
    To     support          the     contention         that    the    ban       on     paid
    circulators       was    properly          designed       to    serve       the    "integrity"
    interest, Colorado asserted "that compensation [for a circulator]
    might provide the circulator with a temptation to disregard" the
    "duty to verify the authenticity of signatures on the petition."
    
    Id. at 426
    .       But, the Court concluded, Colorado had offered "[n]o
    evidence" to substantiate that contention and observed that a
    "professional       circulator['s] . . .                 qualifications           for    similar
    future assignments may well depend on a reputation for competence
    and integrity."         
    Id.
        The Court also noted that Colorado had other
    mechanisms    in    place       to        prevent      signature      fraud        --   such     as
    provisions that criminalized forging signatures on a petition and
    criminalized paying people to sign it -- that "seem[ed] adequate
    to the task of minimizing the risk of improper conduct."                                     
    Id. at 426-27
    . Accordingly, the Court held that the ban could not survive
    the   exacting     scrutiny          that    applied       because      the       ban   was     not
    - 21 -
    "necessary" to serve the state's asserted interest in preserving
    the integrity of the initiative process.            
    Id. at 426
    .
    B.
    Buckley was decided a little over a decade after Meyer.
    It concerned a First Amendment challenge to other restrictions
    that Colorado had imposed with respect to circulating a petition
    for the state's direct initiative process.                  Buckley, 
    525 U.S. at 186
    . Among the restrictions was a requirement that a circulator
    be a registered voter in the state.            
    Id. at 192-93
    .
    The      voter-registration          requirement         necessarily
    required a circulator to be a resident of that state.                  
    Id.
     at 188
    & n.3.     However, no challenge to the residency requirement had
    been brought.       
    Id.
       The Court thus addressed only the portion of
    the voter-registration requirement that required a circulator to
    be not only eligible to vote in Colorado but also registered to do
    so.    
    Id. at 197
    .
    In determining the type of First Amendment scrutiny to
    apply to the voter-registration requirement, the Court emphasized
    that   "[s]tates     allowing    ballot      initiatives    have   considerable
    leeway to protect the integrity and reliability of the initiative
    process,    as     they   have   with     respect   to     election    processes
    generally."      
    Id. at 191
    .     The Court also emphasized that there is
    "'no litmus-paper test'" that "separate[s] valid ballot-access
    - 22 -
    provisions from invalid interactive speech restrictions."             
    Id. at 192
     (quoting Storer v. Brown, 
    415 U.S. 724
    , 730 (1974)); see
    also Timmons v. Twin Cities Area New Party, 
    520 U.S. 351
    , 359
    (1997).   Instead, the Court explained, there is "no substitute for
    the hard judgments that must be made."       Buckley, 
    525 U.S. at 192
    (quoting Storer, 
    415 U.S. at 730
    ).
    At   the   same   time,   the   Court   reaffirmed     Meyer's
    recognition that "[p]etition circulation . . . is 'core political
    speech,' because it involves 'interactive communication concerning
    political change,'" and that "First Amendment protection for such
    interaction . . . is 'at its zenith.'"         Id. at 186-87 (quoting
    Meyer, 
    486 U.S. at 425
    ).     Thus, the Court made a point of stating
    that "the First Amendment requires . . . vigilan[ce] in making
    those judgments" about what distinguishes a valid ballot-access
    restriction from an impermissible speech restriction.      Id. at 192.
    The Court then determined that a most demanding form of
    scrutiny applied to the state restriction at issue.             The Court
    concluded in that regard that the voter-registration requirement
    "produces a speech diminution of the very kind produced by the ban
    on paid circulators at issue in Meyer," id. at 194, which, the
    Court had pointed out there, was subject to a form of scrutiny
    that was "well-nigh insurmountable," Meyer, 
    486 U.S. at 425
    .          The
    Court in Buckley      stated that this means of scrutinizing the
    - 23 -
    restriction at issue was "entirely in keeping with" what the Court
    described as "the 'now-settled approach' that state regulations
    'impos[ing] "severe burdens" on speech . . . [must] be narrowly
    tailored to serve a compelling state interest.'"             Buckley, 
    525 U.S. at
    192 n.12 (alterations and ellipsis in original) (quoting
    
    id. at 206
     (Thomas, J., concurring in the judgment)).
    To support the application of that kind of scrutiny to
    the voter-registration requirement, the Court stated that it was
    "[b]eyond     question"   that   the   voter-registration     requirement
    "drastically reduces the number of persons, both volunteer and
    paid, available to circulate petitions."       
    Id. at 193
    .    Indeed, the
    Court noted, the record in that case showed that the requirement
    rendered at least 400,000 Coloradans -- who were otherwise eligible
    to vote in Colorado but were not registered to do so -- unable to
    serve as petition circulators.         
    Id.
       The Court also highlighted
    testimony that the "'natural support'" for a petition comes in
    part from "'[l]arge numbers'" of people not registered to vote.
    
    Id. at 194
    .
    Equally notably, the Court did not at any point in
    assessing the degree of the burden imposed on core political speech
    by the voter-registration requirement attempt to quantify the
    number of persons that requirement excluded from the pool of
    otherwise available circulators who would be likely to serve as
    - 24 -
    circulators.    See 
    id. at 194-95
    .       Nor did the Court attempt to
    assess whether permitting those excluded from the pool to serve as
    circulators would have increased the likelihood that the petition
    drive in which the plaintiffs were engaged would have secured the
    requisite number of signatures.          See 
    id.
       Instead, the Court
    highlighted the fact that the voter-registration requirement at
    issue "decrease[d] the pool of potential circulators as certainly
    as that pool [was] decreased by the prohibition of payment to
    circulators"    without   separately   analyzing   whether   initiative
    proponents nonetheless could qualify their initiative for the
    ballot.   
    Id.
    In that respect, Buckley followed Meyer.           There, the
    Court noted the fact that the record showed that if initiative
    proponents could pay circulators, more individuals would be "'able
    and willing' to circulate petitions," Meyer, 
    486 U.S. at
    423 n.6
    (record citation omitted), and focused on the proposition that
    proponents who are precluded from hiring circulators are forced to
    either "'find a large number of volunteers . . . or abandon the
    project,'" 
    id. at 423
     (quoting Urevich v. Woodard, 
    667 P.2d 760
    ,
    763 (Colo. 1983) (en banc)).    The Court did not, however, attempt
    to assess with any specificity the actual number of persons that
    would apply to circulate the petition that the plaintiffs intended
    to circulate.    See id. at 422-23.      Nor did the Court attempt to
    - 25 -
    assess whether any of those individuals would be either necessary
    to gathering the number of signatures required for a petition to
    be successful or       more effective at gathering           that number of
    signatures     than   those   who   had   not   been   excluded   from    being
    circulators by the voter-registration requirement.             See id.5
    The Court in Buckley turned next, as it had in Meyer, to
    the question of whether the state's restriction on who may be a
    circulator could survive the demanding form of scrutiny that
    applied.       And,   the   Court   concluded,    as   in   Meyer,   that   the
    restriction could not.        Buckley, 
    525 U.S. at 197
    .
    The Court explained that it found wanting the fit between
    the challenged law and Colorado's "dominant justification" for the
    limitation, which "appear[ed] to be its strong interest in policing
    lawbreakers among petition circulators" for the sake of ensuring
    the integrity of the petition process.             
    Id. at 196
    .       The Court
    concluded that, although Colorado stressed that the applicable
    subpoena power of Colorado's Secretary of State "d[id] not extend
    beyond the State's borders," the State's "interest in reaching law
    5We understand Meyer, and the part of Buckley that
    assessed Colorado's voter-registration requirement which we
    discuss here, to have been identifying the requirements there to
    have imposed a severe burden on core political speech only in the
    context of reviewing a restriction on who may be a circulator. We
    thus do not understand either case to address a First Amendment
    challenge to any other kind of restriction that a state may impose
    that may make it more difficult to place a petition on the ballot.
    See Meyer, 
    486 U.S. at 421-23
    ; Buckley, 
    525 U.S. at 194-96
    .
    - 26 -
    violators . . . [was] served by the requirement . . . that each
    circulator    submit     an    affidavit       setting   out,   among    several
    particulars, the 'address at which he or she resides.'"                       
    Id.
    (quoting 
    Colo. Rev. Stat. § 1-40-111
    (2) (1998)).                The Court also
    explained    that    provisions      of   Colorado   law    that    criminalized
    forging signatures on a petition, that voided certain sections of
    petitions, and that "require[d] sponsors of ballot initiatives to
    disclose who pays petition circulators, and how much," adequately
    served the state's integrity interest.               Id. at 205.       Thus, the
    Court held that, even "assuming that a residence requirement would
    be upheld," the "registration requirement [was] not warranted."
    Id. at 197.
    Although the Court did not identify Colorado's interest
    in   "ensur[ing]       grass     roots      support"       as   its     "dominant
    justification" for the voter-registration requirement we discuss
    here, id. at 196, 205, the Court did explain at the close of its
    opinion   that      Colorado   had    enacted     other,    "less     problematic
    measures" to "meet the State's substantial interests in regulating
    the ballot-initiative process," including "ensur[ing] grass roots
    support."     Id. at 204-05.         "To ensure grass roots support," the
    Court explained, Colorado required that petitions be signed by a
    certain percentage of the state's electorate.               Id. at 205.

    III.
    We begin with an analysis of the plaintiffs' "likelihood
    of success on the merits," which "weighs most heavily in the
    preliminary injunction calculus."         Ryan, 974 F.3d at 18.      The
    defendants do not take issue with the District Court's conclusion
    that if a state law "'impos[es] severe burdens'" on plaintiffs'
    core political speech, then it "'must be narrowly tailored and
    advance   a     compelling    state      interest,'   while   '[l]esser
    burdens . . . trigger less exacting review.'"         We the People PAC,
    519 F. Supp. 3d at 39 (quoting Timmons, 
    520 U.S. at 358
    ).           They
    also recognize the need to explain why Meyer and Buckley -- despite
    their invalidation of the restrictions at issue in them -- do not
    support the District Court's ruling granting the motion for the
    preliminary injunction.      Nonetheless, the defendants contend that
    Meyer and Buckley are distinguishable and that the District Court
    erred in concluding that the plaintiffs are likely to succeed in
    their challenges to the two requirements at issue.         We begin our
    analysis by addressing the plaintiffs' challenge to the residency
    requirement.6
    6 We note that Meyer described the "'core political
    speech'" as "the expression of a desire for political change and
    a discussion of the merits of the proposed change" by a circulator
    - 28 -
    A.
    As we will explain, we agree with the District Court
    that the plaintiffs are likely to succeed in showing that the
    residency requirement does impose a severe burden on core political
    speech, such that it may survive First Amendment review only if it
    is narrowly tailored to serve a compelling state interest.      We
    then will explain why we also conclude that the District Court was
    right to rule that the plaintiffs have met their burden to show
    that they are likely to succeed in showing that the residency
    requirement does violate the First Amendment, insofar as the
    defendants must show that the residency requirement is narrowly
    tailored to serve a compelling state interest.
    1.
    The residency requirement bars all but Maine residents
    from being "circulator[s]."   Me. Stat. tit. 21-A, § 903-A.    The
    requirement thus would appear to bar the petition proponents from
    reaching into a pool of more than 250 million people of voting age
    in her efforts to "persuade potential signatories." Meyer, 
    486 U.S. at 421-22
    .     Moreover, in Buckley, the Court did not
    distinguish in assessing the burden on core political speech that
    the restriction there at issue imposed on those plaintiffs who
    themselves sought to circulate petitions from the burden that the
    restriction imposed on those plaintiffs who were proponents of the
    initiative itself. See Buckley, 
    525 U.S. at

    7 At oral argument, the defendants did suggest that the
    challenged statutes might be read to permit out-of-staters to
    advocate for a petition so long as there is an in-state resident
    who may witness the petition and certify its authenticity to the
    Secretary. But, this late-breaking contention appears to be in
    some tension with arguments that the defendants made below. See
    We the People PAC, 519 F. Supp. 3d at 43 (describing defendants'
    prior position in interrogatories and testimony). We note as well
    that Maine law defines the "circulator" as an individual who
    "solicits signatures for the petition by presenting the petition
    to the voter" and "asking the voter to sign the petition." Me.
    Stat. tit. 21-A, § 903-A; see also We the People PAC, 519 F. Supp.
    3d at 29 ("The legality of using in-state witnesses is unclear.").
    Finally, the defendants do not develop an argument in their
    briefing to us that the relevant state statute, insofar as it may
    be construed to permit the use of in-state witnesses along with
    out-of-state advocates for the petition, would not severely burden
    core political speech. They instead merely state that "the same
    arguments apply" that they have made about why Maine law would not
    severely burden such speech if the statute could not be so
    construed. Thus, any argument that the statute does not severely
    - 30 -
    That is not to say that Maine lacks a compelling interest
    in limiting that pool of potential speakers in the way that the
    residency requirement does.           Nor is it to say that Maine cannot
    show that such a limitation is narrowly tailored to serve that
    interest.    But, at this juncture of the analysis, our concern is
    solely with the threshold question of whether the requirement
    severely burdens core political speech, not whether the burden
    that    requirement    imposes   on    such    speech   is,    though     severe,
    justifiable because it is narrowly tailored to serve a compelling
    interest.    See Buckley, 
    525 U.S. at
    192 n.12.             And, with respect
    to that threshold determination concerning the nature of the burden
    that the requirement imposes, it is "[b]eyond question" that the
    residency requirement imposes a restriction on the available pool
    of circulators that is at least as "drastic[]" as the restrictions
    at issue in either Meyer or Buckley.             Buckley, 
    525 U.S. at 193
    (considering the burden of eliminating from the pool of potential
    circulators "[a]t least 400,000 persons eligible to vote" who "were
    not    registered");   see   also     Meyer,   
    486 U.S. at
    422-23    &   n.6
    (describing testimony that "compensation resulted in more people
    burden core political speech because it may be construed to permit
    the use of in-state witnesses along with out-of-state advocates
    for the petition is waived for the purposes of this appeal. See
    United States v. Kinsella, 
    622 F.3d 75
    , 87 (1st Cir. 2010).
    - 31 -
    being 'able and willing' to circulate petitions" (record citation
    omitted)).
    The defendants are right, of course, that Buckley was
    "careful . . . to differentiate between registration requirements,
    which were before the Court, and residency requirements, which
    were not," Lux v. Rodrigues, 
    561 U.S. 1306
    , 1308 (2010) (Roberts,
    C.J., in chambers).     And it is the latter type of requirement that
    is at issue here.      But, it remains the case that Maine's ban on
    the   use   of   out-of-state   circulators   "drastically    reduces   the
    number of persons, both volunteer and paid, available to circulate
    petitions" and "decreases the pool of potential circulators as
    certainly as that pool is decreased by the prohibition of payment
    to circulators" just as the Court in Buckley found that the voter-
    registration requirement there at issue did.         Buckley, 
    525 U.S. at 193-94
    .
    Buckley did arguably also address whether the reduction
    in the pool of potential circulators, even though drastic, was in
    effect a material one.      
    525 U.S. at 193-94
    .     Buckley highlighted
    testimony in the record that indicated that the pool of otherwise
    eligible voters who were not registered was a pool from which there
    was reason to think circulators would be drawn, because that
    testimony    identified    such   unregistered    voters     as   providing
    - 32 -
    "natural support" for petition drives. 
    Id. at 194
     (record citation
    omitted).
    But, there is evidence of that sort here as well.                 The
    District Court found that there were a significant number of
    "professional petition circulators" residing outside of Maine and
    that     the    plaintiffs      had     identified     only      six   professional
    circulators who were Maine residents.                We the People PAC, 519 F.
    Supp. 3d at 42.         The District Court further found that, as common
    sense would suggest, professional circulators would enhance the
    capacity of proponents of a petition drive to secure signatures.
    See id. at 43.      Indeed, record evidence concerning the plaintiffs'
    experience with the petition drive that they did conduct supported
    that conclusion.         See id. at 42-44.
    The defendants do contend that the District Court should
    not    have     credited      the    plaintiffs'     assertion     that   only   six
    professional circulators could be identified in Maine, see We the
    People    PAC,    519    F.   Supp.    3d   at 42,    on   the   ground   that    the
    plaintiffs "offered few specifics as to how they settled on this
    figure" beyond "inadmissible hearsay."                 But, the District Court
    considered that argument, along with the defendants' evidence that
    the number could be much higher.              See id. at 28 nn.16-17.            And,
    the District Court credited the plaintiffs' "assertion that they
    could    only    identify      six    professional    petition     circulators    in
    - 33 -
    Maine," while excluding as hearsay only some evidence supporting
    that conclusion.      Id. at 28 n.17.
    The District Court did not clearly err in making this
    finding.     The record includes the declaration of the plaintiffs'
    initiative campaign manager, who attested to having "personal
    knowledge" concerning the attitudes of what he described as "the
    few professional petition circulators who are residents" of Maine.
    The     defendants    also   contend     that   "there    are   likely
    thousands"    of    Maine   residents    who   may     not   "make    a    living
    circulating petitions" as professional circulators but would be
    willing to circulate petitions "for pay."                  They then further
    contend that, for this reason, the District Court erred in ruling
    that the residency requirement likely imposes a severe burden on
    core political speech.
    The relevant question, though, is not how many Maine
    residents might be willing to circulate a petition if paid to do
    so.   The relevant question is whether the residency requirement
    excludes from the pool of potential circulators a sufficiently
    significant    number    of     individuals    --    including      professional
    circulators that could enhance the reach of the campaign -- who
    may reside outside of Maine.
    The defendants do also argue that the plaintiffs are not
    likely to succeed in showing that the requirement imposes a severe
    - 34 -
    burden on core political speech because "the record is replete
    with evidence of successful citizen initiative and people's veto
    campaigns in Maine."      For example, they point to the fact that
    "one recent campaign collected approximately 100,000 signatures
    using 616 Maine circulators during the same three-month period
    that [the p]laintiffs' campaign was active."
    We are not persuaded by this argument. We have no reason
    to doubt that, despite the residency requirement, petition drives
    may employ Maine residents as circulators and may even succeed by
    doing so.     But, Meyer and Buckley each rejected a contention that
    the existence of an alternative means of securing the requisite
    number of signatures for a petition in and of itself "lift[s] the
    burden on speech at petition circulation time."           Buckley, 
    525 U.S. at 195
    ; see also Meyer, 
    486 U.S. at 424
    .                 Indeed, the Court
    concluded in Meyer that the "burden on First Amendment expression"
    was not mitigated "because other avenues of expression remain[ed]
    open"   to   the   proponents;   it   explained   that    the   Constitution
    protects the right "not only to advocate the[] cause but also to
    select what [the proponent] believe[s] to be the most effective
    means for so doing."     
    486 U.S. at 424
    ; see also We the People PAC,
    519 F. Supp. at 42-43.
    Nor are we persuaded by the defendants' argument that
    the District Court erred in concluding that the requirement likely
    - 35 -
    imposed a severe burden on political speech by relying on the
    mistaken (or, at least, unsupported) premise that out-of-state
    circulators    --      and   especially         out-of-state    professional
    circulators -- are more effective than in-state circulators when
    the plaintiffs had made no showing to substantiate it.                   The
    District Court did not point to the burden that the residency
    requirement   placed    on   the   use    of    "out-of-state   professional
    petition   circulators"      to    make   the    point   that   out-of-state
    residents would, as a general matter, make for better circulators
    than in-state circulators.         The District Court pointed to that
    burden instead to make the separate point that Maine's residency
    requirement drained from the "pool" of potential circulators those
    who were professionals in the work of circulating petitions -- and
    may therefore be more efficient than non-professional circulators
    -- and who also resided outside Maine.            We the People PAC, 519 F.
    Supp. 3d at 42-43.
    The defendants next assert that the District Court erred
    in concluding that strict scrutiny likely applied because "[t]here
    is also no record evidence that Maine's residency requirement
    unconstitutionally increased the cost" of the plaintiffs' petition
    drive.   But, even assuming that the defendants are right that out-
    of-state circulators cost "a premium," the fact that the plaintiffs
    may be willing to pay such a premium only highlights the severity
    - 36 -
    of Maine's "limit[ation]" on "the number of voices who will convey
    [the plaintiffs'] message and the hours that they can speak and,
    therefore, . . . [on] the size of the audience they can reach,"
    Meyer, 
    486 U.S. at 422-23
    .
    Finally, we observe, as the District Court did, that the
    conclusion that the plaintiffs are likely to succeed in showing
    that the residency requirement must be subjected to strict scrutiny
    draws substantial support from lower court precedent.                        We the
    People PAC, 519 F. Supp. 3d at 40-41.                 See Yes On Term Limits,

    , 855, 862 (7th Cir. 2000)
    (applying "exacting scrutiny" to a voter-registration requirement
    for    circulators   of    candidate-nominating   petitions   that     also
    imposed a state-residency requirement).
    The defendants are right that all but one of these
    precedents addressed residency requirements for circulators of
    candidate-nominating petitions.       See Libertarian Party of Va., 718
    F.3d at 311-12; Brewer, 
    531 F.3d at 1031
    ; Blackwell, 
    545 F.3d at 462
    ; Wilmoth, 731 F. App'x at 99; Krislov, 
    226 F.3d at 856
    .            But,
    the defendants do not explain why that feature of those cases
    renders those precedents off point in evaluating a functionally
    analogous restriction on who may circulate a petition for a direct
    initiative.      Indeed, all but one of the candidate-nominating
    precedents apply or rely on cases that apply the Meyer-Buckley
    framework to analyze the level of scrutiny that applies.               See
    Libertarian Party of Va., 718 F.3d at 316-17; Brewer, 
    531 F.3d at 1035-36
    ; Wilmoth, 731 F. App'x at 102-03; Krislov, 
    226 F.3d at 859-62
    .    The one precedent that arguably may be read to not so
    hold, moreover, provides no basis for concluding that the Meyer-
    Buckley framework is inapplicable or leads to a different result
    here    simply   because    a   candidate-nominating   petition   is   not
    involved.    See Blackwell, 
    545 F.3d at 459, 474-75
     (lead opinion of
    - 38 -
    Boggs, C.J.); 
    id. at 478
     (Moore, J., and Clay, J., each separately
    concurring in part and in the judgment).
    The    defendants     do    cite    to     Initiative     &   Referendum
    Institute v. Jaeger, an Eighth Circuit decision that upheld a
    state-residency         requirement       for      circulators         of   initiative
    petitions.      
    241 F.3d 614
    , 615 (8th Cir. 2001).                     That case does
    state that certain evidence in the record there "demonstrates that
    no severe burden has been placed on those wishing to circulate
    petitions."         
    Id. at 617
    .     But, even if the Eighth Circuit may be
    read to hold that the residency requirement was not subject to
    strict scrutiny         because it imposed no severe burden on core
    political speech, see 
    id. at 616
     (explaining that "the State ha[d]
    a compelling interest in preventing fraud and the regulation [did]
    not    unduly   restrict     speech"      and     thus    "conclud[ing]      that   the
    residency requirement [was] constitutional."); Wilmoth, 731 F.
    App'x    at   102     (describing    Jaeger       as    having   "appl[ied]     strict
    scrutiny review"), it invoked the "high success rate" of signature
    campaigns as "demonstrat[ing] that no severe burden has been placed
    on those wishing to circulate petitions." Jaeger, 
    241 F.3d at 617
    .
    Such    reasoning      conflicts,    however,          with   Meyer,   which   applied
    exacting scrutiny after pointing to "the possibility that even
    more petitions would have been successful if paid circulators had
    been available."        Meyer, 
    486 U.S. at
    418 n.3, 420.

    The defendants          independently rely on an unpublished
    decision from the federal District Court for the District of Maine,
    see Initiative & Referendum Inst. v. Sec'y of State of Me., No.
    Civ. 98–104, 
    1999 WL 33117172
     (D. Me. Apr. 23, 1999), which the
    Eighth Circuit cited approvingly, see Jaeger, 
    241 F.3d at 617-18
    .
    The district court declined in that case to apply strict scrutiny
    to   Maine's   state-residency           requirement     for     circulators.          See
    Initiative & Referendum Inst., 
    1999 WL 33117172
    , at *16.                        But, the
    district   court     there      did    not      assess    whether       the   residency
    requirement      would    drastically          reduce    the    available       pool   of
    circulators, which is the relevant question here.                        
    Id.
     at *16 &
    n.18.
    The defendants are right that there are other circuit
    court   decisions        that   have      not     applied      strict    scrutiny      to
    restrictions      that     pertain        to    petition       circulators.            See
    Libertarian Party of Ohio v. Husted, 
    751 F.3d 403
    , 413-18 (6th
    Cir. 2014)     (declining to apply strict scrutiny to                         state law
    requiring "circulators of candidacy or nomination petitions to
    disclose   the    name    and     address       of"   their    employer);       Prete v.
    Bradbury, 
    438 F.3d 949
    , 963, 968 (9th Cir. 2006) (restriction on
    specific   payment       scheme    for    circulators         imposes    only   "lesser
    burden" on speech).        But, the nature of the restrictions in those
    cases differs from that of the residency requirement at issue here.
    - 40 -
    Finally, the defendants highlight the fact that Maine's
    highest court declined to apply strict scrutiny to the provisions
    of the Maine Constitution that require circulators of direct
    initiatives to be state residents.          See Hart, 
    715 A.2d at 168
    .
    But,   significantly,    Hart,    which   was   decided   before   Buckley,
    distinguished Meyer on the ground that the plaintiff in Hart "had
    three years to gather the necessary signatures and failed to
    demonstrate   any     necessity     for    employing      nonresidents   in
    circulating the petitions."       
    Id.
     (citation omitted).       Yet, as we
    have explained, it is clear after Meyer and Buckley that the
    determination of whether a restriction on who may be a circulator
    imposes a severe burden on core political speech is not dependent
    on whether it is necessary for the ballot measure's proponents to
    be able to enlist those who are subject to the restriction to
    obtain the requisite number of signatures.           See Meyer, 
    486 U.S. at
    418 n.3; Buckley, 
    525 U.S. at 195
    .
    Thus,    the record supports the conclusion that the sheer
    "reduc[tion in] the number of persons . . . available to circulate
    petitions" as a result of the residency requirement at issue here
    is at least as "drastic[]" as it was as a result of the registration
    requirement that the Court addressed in Buckley, 
    525 U.S. at
    193
    & n.15 (considering the exclusion of less than one million people
    "eligible" but not "registered" to vote).          Similarly, the record
    - 41 -
    supports the conclusion that the residency requirement imposes a
    material limitation on the proponents' ability "to select what
    they believe to be the most effective means" to "advocate their
    cause" as in Meyer, 
    486 U.S. at 424
    .          Accordingly, we are not
    persuaded by the defendants' arguments that the District Court
    erred in concluding that the plaintiffs are likely to succeed in
    showing that strict scrutiny applies to the requirement because it
    imposes a severe burden on core political speech.
    2.
    We move on, then, to the next stage of the inquiry, which
    concerns whether the residency requirement serves a compelling
    state interest in a narrowly tailored manner.            The defendants
    assert two compelling interests: "ensuring that circulators can be
    located easily and efficiently" to combat petition fraud, and
    "protecting the very means by which Mainers exercise their right
    to legislate," by ensuring "that a power held by Mainers is
    administered -- and policed -- by Mainers."            We consider each
    interest in turn, as well as the extent to which the residency
    requirement is narrowly tailored to serve each one.         We conclude,
    as we will explain, that the District Court did not err in holding
    that the plaintiffs are likely to succeed in their First Amendment
    challenge    to   the   residency    requirement,   notwithstanding   the
    - 42 -
    defendants' arguments about why that requirement survives even
    strict scrutiny.
    a.
    The District Court did not question the first of the
    defendants' asserted          compelling interests, which the District
    Court described as Maine's "strong interest in protecting its
    elections." We the People PAC, 519 F. Supp. 3d at 46. The District
    Court   concluded       instead       that,     even       if   Maine's    interest    in
    "monitor[ing] and prosecut[ing] petition fraud" is compelling, the
    plaintiffs   are       likely    to     succeed       in    demonstrating     that    the
    defendants cannot show that the residency requirement is narrowly
    tailored to serve that interest.                Id.    We agree.
    As     we   have     seen,    Meyer    rejected        the     argument    that
    Colorado's ban on paid circulators was narrowly tailored to serve
    a like interest.        
    486 U.S. at 426-27
    .                Meyer pointed as support
    for that conclusion to "[o]ther provisions" of Colorado law that
    expressly imposed penalties for petition fraud as "adequate to the
    task of minimizing the risk of improper conduct in the circulation
    of a petition, especially since the risk of fraud or corruption,
    or the appearance thereof, is more remote at the petition stage of
    an   initiative    than    at    the     time    of    balloting."          
    Id.
          Those
    provisions made it "a crime to forge a signature on a petition, to
    - 43 -
    make false or misleading statements relating to a petition, or to
    pay someone to sign a petition."         
    Id. at 427
     (citations omitted).
    Buckley is no different.       It rejected an argument that
    Colorado's voter-registration requirement was narrowly tailored to
    serve   the    state's   interest   in   preserving   election     integrity,
    explaining that Colorado's "interest in reaching law violators"
    was served by a requirement "that each circulator                  submit an
    affidavit setting out, among several particulars, the 'address at
    which he or she resides.'"          
    525 U.S. at 196
     (quoting 
    Colo. Rev. Stat. § 1
    –40–111(2) (1998)).
    Nothing indicates that there is a better fit here between
    the interest in election integrity that Maine asserts and the
    restriction on who can be a circulator that Maine has imposed
    through its residency requirement, at least "as [that requirement
    is] applied to out-of-state circulators who first submit to the
    jurisdiction of the state of Maine" for alleged violations of Maine
    law.    We the People PAC, 519 F. Supp. 3d at 53; cf. Tenn. Wine &
    Spirits Retailers Ass'n v. Thomas, 
    139 S. Ct. 2449
    , 2457, 2461-
    62, 2475 (2019) (holding that state's residency requirement for
    the issuance of a license to operate a liquor store could not
    survive   Twenty-First     Amendment     scrutiny,    despite   the   state's
    contention that the requirement ensured amenability to process in
    state     courts     and    state     regulatory      oversight,      because
    - 44 -
    "alternatives" such as "requiring a nonresident to . . . consent
    to suit" and "on-site inspections" remained available).                Nor are
    we persuaded by the defendants' arguments to the contrary.
    The defendants contend that Maine's interest in the
    integrity of its elections "is not limited to the ability to force
    circulators to return to the state," because that interest also
    extends   to   "being      able   to    quickly   and   efficiently     contact
    circulators    to,   for    example,     investigate    potential     signature
    fraud." For that reason, the defendants contend, even though Maine
    could subpoena out-of-state circulators, that option "is hardly a
    realistic" one for the Secretary to exercise during the thirty-
    day petition review period.
    But, Maine law already requires circulators to disclose
    in an affidavit "the physical address" at which they reside.                Me.
    Stat. tit. 21-A, ch. 11, § 903-A(4)(A). Furthermore, a requirement
    that circulators provide up-to-date contact information and submit
    to legal process is, like the requirement that circulators provide
    an "address attestation" identified in Buckley, an alternative
    that "has an immediacy, and corresponding reliability" that a mere
    requirement that the circulator be a Maine resident "lack[s]," 
    525 U.S. at 196
    .
    The defendants also do not explain why -- in this day
    and age -- resident circulators are so much easier to contact than
    - 45 -
    nonresident circulators that a flat-out ban on out-of-staters is
    necessary.     Nor have the defendants explained why Maine could not
    further its interest on this score just as effectively by requiring
    out-of-state      circulators          to    provide      up-to-date        contact
    information.     See Buckley, 
    525 U.S. at 196
    .
    A substantial body of out-of-circuit precedent accords
    with this analysis, as the District Court pointed out.                    See We the
    People PAC, 519 F. Supp. 3d at 46-47; see also Brewer, 
    531 F.3d at 1037
     ("Federal        courts    have    generally      looked     with    favor    on
    requiring     petition         circulators      to    agree      to      submit    to
    jurisdiction . . . and the courts have viewed such a system to be
    a more narrowly tailored means than a residency requirement to
    achieve the same result."); Yes on Term Limits, Inc., 
    550 F.3d at 1029-30
    ; Libertarian Party of Va., 718 F.3d at 318.                   Such contrary
    precedent as there is, moreover, does not lead us to conclude that
    the   District    Court's        application     of    the      narrow    tailoring
    requirement was mistaken.
    The defendants are right that the Eighth Circuit held in
    Jaeger that North Dakota's residency requirement for petition
    circulators     was     constitutional       because    the      state    "ha[d]    a
    compelling interest in preventing fraud," and that the requirement
    "allow[ed]" the state "to protect the petition process from fraud
    and abuse by ensuring that circulators answer to [its] subpoena
    - 46 -
    power."   
    241 F.3d at 616
    .   But, the plaintiffs in that case did
    not propose, and the Eighth Circuit did not consider, the narrower
    means of achieving that interest that we find available here:
    requiring out-of-state circulators to provide up-to-date contact
    information and to submit to legal process in the state.   See id.;
    Brief of Appellants at 38-42, Initiative & Referendum Institute v.
    Jaeger, 
    241 F.3d 614
     (8th Cir. 2001) (No. 99-3434).
    The defendants also rely for their position on the Maine
    Law Court's opinion in Hart, which they describe as having found
    that the residency requirement "serves the Secretary's important
    interest in making 'circulators easier to locate if there is a
    question as to the validity of the signatures collected'" (quoting
    Hart, 
    715 A.2d at 168
    ).   But, the plaintiffs in that case did not
    argue in their brief to that court that Maine could instead require
    circulators to submit to legal process or provide their contact
    information to the state.    See Hart, 
    715 A.2d at 168
    ; Brief of
    Appellants, Hart v. Sec'y of State, 
    715 A.2d 165
     (Me. 1998), 
    1998 WL 35076164
    , at *16-18; see also Brief of Appellee, Hart v. Sec.
    of State, 
    715 A.2d 168
     (Me. 1998), 
    1998 WL 34501218
    , at *9-20.
    Indeed, aside from the single sentence in its opinion in which the
    Maine Law Court stated that the residency requirement "provide[d]
    the State with jurisdiction over the circulators and ma[de] the
    circulators easier to locate," the Law Court did not further
    - 47 -
    explain its basis for concluding that interest was one that Maine's
    residency requirement was narrowly tailored to serve.       See Hart,
    
    715 A.2d at 168
    .
    The defendants also point to the role that circulators
    play in what the Maine Law Court described in Hart as "preserving
    the integrity of the law-making process."     Hart, 
    715 A.2d at 168
    .
    In Meyer, however, the Court was "not prepared to assume" that a
    paid circulator was "any more likely to accept false signatures"
    than a circulator who was "motivated entirely by an interest in
    having the proposition placed on the ballot."       
    486 U.S. at 426
    .
    We see no reason here to make the assumption that Meyer declined
    to make simply because a paid circulator is not a Maine resident.
    We thus reject the contention that the District Court
    erred in ruling that the plaintiffs were likely to succeed in
    showing that the residency requirement is not narrowly tailored to
    serve the state's interest in protecting the integrity of its
    elections.   And that is so even if we account for Maine's asserted
    interest in efficiently locating circulators.
    b.
    The   defendants   separately   argue   that   Maine   has   a
    compelling interest "in limiting participation in its political
    process to its residents" (quoting Initiative & Referendum Inst.,
    
    1999 WL 33117172
     at *15).    Here, the District Court rejected what
    - 48 -
    it described as the defendants' "grassroots interest" argument.
    See We the People PAC, 519 F. Supp. 3d at 47-48.       It did so on the
    ground that, as in Meyer, 
    486 U.S. at 425-26
    , and Buckley, 
    525 U.S. at 205
    , Maine already requires that successful initiative
    petitions consist of a minimum number of signatures, and that it
    further requires that the petition "be signed by Maine citizens
    and approved by Maine voters on election day before becoming law."
    We the People PAC, 519 F. Supp. 3d at 47-48.     We agree.
    The defendants argue otherwise based in part on Holt
    Civic Club v. City of Tuscaloosa, 
    439 U.S. 60
    , 68-69 (1978).
    There, the Court explained that its precedents "have uniformly
    recognized that a government unit may legitimately restrict the
    right to participate in its political processes to those who reside
    within   its   borders."   
    Id. at 68-69
    .   But,   Holt   concerned
    participation in the political process through voting rather than
    through the circulation of a petition. 
    Id. at 61-63, 66-69
    .      Thus,
    the fact that Holt upheld a limitation on the voting rights of
    non-residents does not show that a limitation on the right of non-
    residents to circulate a petition is constitutional, as Buckley
    itself makes clear.    See Buckley, 
    525 U.S. at
    196 n.17.
    The defendants also rely on the unpublished opinion in
    Initiative & Referendum Institute v. Secretary of State, in which
    the District Court for the District of Maine stated that "Maine's
    - 49 -
    interest in limiting participation in its political process to its
    residents is compelling" and that Maine could permissibly require
    petition circulators to be Maine residents due to the "vital role"
    that circulators play "in the process of self-government."     
    1999 WL 33117172
     at *15 (citing Holt, 
    439 U.S. at 68-69
    ).   Although the
    defendants do not expand on this "self-government" argument, they
    do advance the related contention that "[t]he initiative power is
    a legislative right reserved in Maine's Constitution for Maine's
    residents, and the exercise of that power is not limited to signing
    a petition or voting for an initiative, but rather includes the
    circulation of petitions."
    But, in Meyer the Court rejected the argument "that
    because the power of the initiative is a state-created right,
    [Colorado] is free to impose limitations on the exercise of that
    right."   
    486 U.S. at 424
    .   The Court explained that "the power to
    ban initiatives entirely" does not "include[] the power to limit
    discussion of political issues raised in initiative petitions."
    
    Id. at 425
    .   Nor, as we have already explained, is this a case in
    which either the state measures imposing the restrictions or the
    defendants' interpretation of them provides any legal clarity as
    to whether out-of-state circulators are permitted to engage in
    petition circulation when accompanied by an in-state "witness,"
    see We the People PAC, 519 F. Supp. 3d at 29-30, such that it is
    - 50 -
    evident that the residency requirement does not severely burden
    "core political speech," id. at 53.
    The defendants relatedly contend that the residency
    requirement   is    narrowly    tailored    to   serve    their   interest   in
    "limiting the responsibility of circulation" to "those who possess
    the right to advance and pass citizen legislation and must live
    under any resulting law."        They cite for this proposition to the
    Maine Law Court's decision in Hart, which found that Maine's
    residency requirement "enhances the integrity of the initiative
    process by ensuring that citizens initiatives are brought by
    citizens of Maine."     
    715 A.2d at 168
    .
    But, in light of Meyer and Buckley, we fail to see why
    banning non-resident circulators is narrowly tailored to serve
    that interest. After all, only the individuals who must live under
    any resulting law may sign the petition, see Me. Const. art. IV,
    pt. 3, § 20, and only Maine voters may vote to approve any measure
    that does reach the ballot by way of a successful petition.                  See
    We the People PAC, 519 F. Supp. 3d at 47.                In addition, as the
    District Court noted, the defendants have not argued that Mainers
    are "especially vulnerable to blandishments from out-of-state
    circulators."      Id. at 48.
    - 51 -
    3.
    Thus, on the record before us, the residency requirement
    likely    "inhibit[s]       communication        with    voters   about     proposed
    political change" and is likely "not warranted by the state
    interests . . . alleged to justify [it]."                   Buckley, 
    525 U.S. at 192
    .      We    therefore    agree   with      the   District     Court    that   the
    plaintiffs have established that they are likely to succeed in
    proving    that     the     residency     requirement       violates      the   First
    Amendment.
    B.
    We turn now to Maine's voter-registration requirement
    for the circulation of petitions.                 We first conclude that the
    District Court did not err in ruling that this requirement also
    likely is subject to strict scrutiny.                   We then further conclude
    that, given the interests that Maine has asserted, the plaintiffs
    have met their burden to show that the requirement is not likely
    to survive that level of scrutiny.
    1.
    With respect to the burden that the voter-registration
    requirement imposes, it is problematic -- as the plaintiffs suggest
    -- to consider only the portion of that requirement that concerns
    the act of registering in the abstract.                 The requirement is not to
    be a registered voter somewhere.                  It is a requirement to be
    - 52 -
    registered to vote in Maine, Me. Stat. tit. 21-A, § 903-A, which
    is possible only if one is otherwise eligible to vote in Maine,
    see Me. Const. art. II, § 1, and which means that the requirement
    necessarily excludes those not meeting the residency requirement.
    In challenging the District Court's ruling as to the
    registration requirement, the defendants begin by contending that
    "if the residency requirement does not impose a severe burden,
    then the registration requirement does not do so, either."                 But,
    they develop no argument in favor of the converse -- namely, that
    if the residency requirement does likely impose a severe burden,
    the registration requirement does not.            Instead, they merely argue
    that the additional burden imposed by the registration requirement
    beyond the residency requirement is minimal, such that it does not
    result in the imposition of a severe burden on core political
    speech insofar as the residency requirement itself does not.
    To   that      point,      the     defendants     contend    that
    "[r]egistering to vote in Maine is both easy and straightforward."
    They   also    assert     that   only    three   percent   of   eligible   Maine
    residents are not registered to vote, which, by their own account,
    excludes at least the 32,000 Maine residents who are eligible but
    - 53 -
    not registered to vote from serving as circulators.8         And, in
    support of that contention, the defendants point to two cases that
    have   upheld   Maine's   voter-registration   requirement     after
    concluding that it did not impose a severe burden on core political
    speech given the relatively small number of Mainers who were
    excluded from serving as circulators.   See Initiative & Referendum
    Inst., 
    1999 WL 33117172
    , at *15; Jones, 238 A.3d at 992 ("[T]he
    individual circulators whose petitions are in dispute here were
    not opposed to registering to vote and indeed became registered
    voters in their municipalities, albeit after they circulated the
    disputed petitions.").
    But, even if we were to assume that a restriction that
    would exclude tens of thousands of possible circulators would not
    for that reason alone severely burden core political speech, see
    Buckley, 
    525 U.S. at 193, 194-95
     (describing burden imposed by
    voter-registration requirement that excluded 400,000 Coloradan
    residents from serving as circulators (citing Meyer, 
    486 U.S. at 422
    )), the residency requirement, as we have explained, does
    8 As the District Court observed, that number may even
    be higher, as Maine's Constitution requires not merely that
    prospective circulators be registered to vote in Maine but also
    that they be registered to vote in the specific "city, town or
    plantation" in which they reside.    Me. Const., art. IV, pt. 3,
    § 20; We the People PAC, 519 F. Supp. 3d at 32, 50, 51. Although
    the defendants contend that the District Court did not rely on any
    evidence for the proposition that the number therefore "must be"
    higher, id. at 51, the inference that it would be is reasonable.
    - 54 -
    likely impose a severe burden on core political speech.            Thus, in
    light of that ruling, we have no basis here, given the defendants'
    own   contentions,   to   conclude      that    the   voter-registration
    requirement does not likely do so as well.
    2.
    The   defendants    appear    to   acknowledge   that,    if   the
    residency requirement cannot survive strict scrutiny, then neither
    can the voter-registration requirement insofar as it "serves the
    residency requirement."      Nonetheless, the defendants contend that
    the registration requirement can survive such scrutiny even if the
    residency requirement cannot, because it is a standalone means of
    "serv[ing] the same integrity interest that residency does."
    The defendants assert in support of that contention that
    the registration requirement serves this integrity interest by
    "limit[ing] participation" in the initiative process "to those who
    are invested enough to take the trouble to register to vote"
    (quoting Initiative & Referendum Inst., 
    1999 WL 33117172
    , at *15).
    The requirement does so, they further assert, because it "ensures
    that each circulator has a vested interest in the initiative they
    hope to pass, in that each will be able to vote on that initiative
    should it qualify for the ballot."
    The defendants cite as support for this contention to
    Initiative & Referendum Institute v. Secretary of State, 1999 WL
    - 55 -
    33117172, at *15.     But, the court there did not apply strict
    scrutiny to the voter-registration requirement.    
    Id.
       It thus did
    not assess whether that restriction was narrowly tailored to serve
    the state's purported interest in limiting participation in the
    initiative process.   
    Id.
       Moreover, we see no basis in the record
    for assuming that circulators who are not registered to vote in
    Maine will be less likely to abide by an oath to verify the validity
    of the signatures that they witness, or otherwise to go about the
    petitioning business in accordance with Maine's laws, than those
    who are not.   Cf. Meyer, 
    486 U.S. at 426
     ("[W]e are not prepared
    to assume that a professional circulator . . . is any more likely
    to accept false signatures than a volunteer . . . ."); Buckley,
    
    525 U.S. at 203-04
    .
    So, for these reasons, we agree with the District Court
    that it is likely that the voter-registration requirement does not
    appropriately fit the asserted integrity interest.       And, to the
    extent that the integrity interest the defendants advance here is
    just a way of restating the interest in limiting the "initiative
    power" to "Maine's residents" that they advance in defense of the
    residency requirement, it is problematic for the same reason that
    such a contention is in that context.
    In the absence of a compelling state interest to which
    the voter-registration requirement is narrowly tailored, we cannot
    - 56 -
    conclude that it survives strict scrutiny.                See Buckley, 
    525 U.S. at
    192 n.12.     Thus, as is the case with the residency requirement,
    we conclude that the District Court did not err in holding that
    the plaintiffs are likely to succeed on the merits of their First
    Amendment challenge to the voter-registration requirement.                       And,
    we note that this decision is in accord with decisions of our
    sister circuits, as none in the wake of Buckley has upheld such a
    restriction after applying strict scrutiny.                 See Blackwell, 
    545 F.3d at 478
     (Moore, J., concurring in part and in the judgment)
    ("We   hold    that   the    voter-registration         requirement . . .        is    a
    severe restriction on political speech which cannot survive strict
    scrutiny."); Krislov, 
    226 F.3d at 856, 866
     (striking requirement
    that circulators "be registered to vote in the same political
    subdivision for which the candidate is seeking office" as not
    meeting "exacting scrutiny").
    IV.
    There   remains    to   address     the    other    factors   in    the
    preliminary     injunction      analysis     --   first,    the     potential     for
    "irreparable harm," second, "the balance of relative hardships,"
    and third, the question whether an injunction would be in the
    "public interest."          See Ryan, 974 F.3d at 18.            We begin with the
    last two factors, as the analysis of them is straightforward.                         We
    continue to review for abuse of discretion, mindful that "[a]part
    - 57 -
    from error of law, an abuse of discretion occurs when the district
    court considers improper criteria, ignores criteria that deserve
    significant weight, or gauges only the appropriate criteria but
    makes a clear error of judgment in assaying them."        Rosario-
    Urdaz v. Riviera-Hernandez, 
    350 F.3d 219
    , 221 (1st Cir. 2003).
    A.
    In arguing that the District Court erred in determining
    that the "balance of relative hardships" and "public interest"
    factors favored granting the preliminary injunction, Ryan, 974
    F.3d at 18, the defendants contend that the plaintiffs unduly
    delayed in filing their lawsuit and that the District Court should
    not have permitted them "to manufacture a need for extraordinary
    relief through their own lack of diligence."     See Respect Maine
    PAC, 
    622 F.3d at 16
     (concluding "this 'emergency' is largely one
    of [plaintiffs'] own making" where, "well aware of the requirements
    of the election laws," they "chose" not to sue until approximately
    three months prior to an election date).    The defendants further
    contend that "this case concerns a core right held by all Maine
    residents" and that the preliminary injunction therefore harms the
    "public -- namely, Mainers" and their "interest in protecting the
    integrity of a legislative power reserved to them under their state
    constitution."
    - 58 -
    But, the District Court did not abuse its discretion in
    ruling that, even though the plaintiffs' delay in filing their
    lawsuit "put the Court in the undesirable position of considering
    an important constitutional challenge on an expedited basis," the
    "constitutional challenge" before it was "both meritorious and
    important."      We the People PAC, 519 F. Supp. 3d at 52.         Moreover,
    the   District    Court   recognized    the   public's   "strong   competing
    interests" in "the regulation of referendum petitions and in
    protecting the integrity and grassroots nature of the direct
    initiative and people's veto power" on the one hand, and in
    "ensuring the freedom of speech and constitutionality of election
    laws" on the other.       Id.   It then reasonably concluded that "the
    public has a greater interest in upholding its constitutionally
    protected freedom of speech."       Id.
    B.
    That leaves only the defendants' arguments with respect
    to "the potential for irreparable harm in the absence of an
    injunction."      González-Droz v. González-Colon, 
    573 F.3d 75
    , 79
    (1st Cir. 2009).       With respect to the plaintiffs' then-ongoing
    campaign for which they had not gathered sufficient signatures,
    the District Court concluded that the plaintiffs had "shown a
    severe burden and [we]re not required to further prove that it is
    impossible to gather enough signatures under the current law."           We
    - 59 -
    the People PAC, 519 F. Supp. 3d at 52; see also id. at 51 ("The
    loss of First Amendment freedoms, for even minimal periods of time,
    unquestionably constitutes irreparable injury." (quoting Elrod v.
    Burns, 
    427 U.S. 347
    , 373 (1976))).        The defendants appear to agree
    with that description of what the plaintiffs must show to satisfy
    the irreparable harm requirement.
    The   District    Court     determined   that    the   plaintiffs'
    showing   with   respect    to   the   likelihood   of     this   "continuing
    deprivation" of their First Amendment rights also shows that they
    are likely to suffer "an irreparable harm."          See 
    id.
          The District
    Court acknowledged in so ruling that it was issuing the preliminary
    injunction on the day on which the plaintiffs' petition had to be
    submitted to municipal officials for certification of signatures
    so that it could be filed with the Secretary's office for placement
    of that initiative on the November 2022 ballot.              See id. at 44,
    52.   But, the District Court held that "while an injunction might
    make no real difference for the [then-]current petition drive,"
    the plaintiffs would "continue to suffer harm in their next
    petition drive," and identified a "continuing deprivation" that
    "acts as an irreparable harm" on that basis as well.               Id. at 52.
    The District Court then preliminarily enjoined the requirements as
    to future drives.    Id. at 53.
    - 60 -
    The defendants argue to us that the District Court abused
    its discretion in this regard by relying on "a hypothetical future
    campaign"    to     conclude       that    the    plaintiffs     were    at    risk   of
    irreparable injury.           They contend that the "contingency plan" to
    initiate a new petition drive "cannot, as a matter of law . . .
    establish a likelihood of irreparable harm" because it is too
    uncertain.    See In re Rare Coin Galleries, Inc., 
    862 F.2d 896
    , 902
    (1st Cir. 1988) ("Speculation or unsubstantiated fears of what may
    happen in the future cannot provide the basis for a preliminary
    injunction.").
    But,       when    asked       in     an     interrogatory       about    the
    implications      of    the   timing       of    their    lawsuit,     the   plaintiffs
    explained    that      even   if    they    did    not    make   the    February     2021
    deadline, they would be able to "immediately refile the initiative
    petition and still make the 2022 ballot if they file[d] signatures
    from a new petition drive with signatures collected from March
    2021 to January 2022."          And while the defendants contend that this
    statement did not constitute a "commitment to a new campaign" and
    to apply for a new initiative petition form, but merely indicated
    the plaintiffs' awareness of the relevant deadlines should they
    choose to "'refile,'" the statement in context is fairly construed
    as a representation that the plaintiffs' reasons for seeking a
    - 61 -
    preliminary       injunction   would    persist   past   the   then-impending
    February 16, 2021 deadline.9
    We also are not persuaded by the defendants' challenge
    to the finding of irreparable harm on the ground that, even if the
    record does show that the plaintiffs intended to file future
    petitions, "[t]he record does not touch upon preparations for any
    future campaign, or predictions for how a new campaign, which could
    be conducted during the summer of 2021 and in an improving pandemic
    environment, would unfold."            As we have explained in addressing
    the "likelihood of success" prong of the analysis, the burden on
    core political speech that the residency- and voter-registration
    requirements each imposes arises from the drastic limitation on
    the   pool       of   out-of-state   circulators    that   each   inherently
    imposes.10
    The record also contains the signed declaration of the
    9
    President of plaintiff Liberty Initiative Fund stating that
    Liberty Initiative Fund "seeks relief from these restrictions not
    only so that [it] can reach enough people to place the Citizen
    Voting initiative on the 2022 ballot, but so that [it] can, working
    with We the People PAC and other Mainers, place other reform
    measures . . . on the ballot in 2022 and 2024." The defendants do
    not appear to have disputed this statement below, nor do they do
    so on appeal.
    The defendants separately contend that if the
    10
    plaintiffs truly "had premised their request for a preliminary
    injunction on long-term harm to a future campaign," then "the
    - 62 -
    V.
    The   order   issuing   the   preliminary   injunction   is
    Affirmed.
    Secretary would . . . have insisted on the development of a full
    preliminary   injunction   record  and   traditional   sequential
    briefing." But, the defendants do not identify any arguments that
    they were unable to make or evidence that they were unable to
    collect as a result of the District Court's docket management
    practices. We also note that the defendants have not advanced any
    separate argument that, even if there has been a showing of
    irreparable harm with respect to the filing of future initiative
    petitions, that showing cannot support a preliminary injunction
    with respect to the petitioning process for any post-2022 ballot
    measures or with respect to the restrictions on circulators of
    petitions for a people's veto. The parties are free on remand to
    address any issue in that regard.
