    SUMMARY *
    Habeas Corpus / Death Penalty
    The panel affirmed the district court’s denial of
    California state prisoner Paul Bolin’s habeas corpus petition
    challenging his jury conviction for two counts of first-degree
    murder and his capital sentence.
    Applying the deferential standards of review in the
    Antiterrorism and Effective Death Penalty Act, the panel
    held that the district court properly denied Bolin’s claims
    that his trial counsel was ineffective in not renewing a
    motion to change venue based on pretrial publicity and in
    failing to develop additional mitigating evidence.
    The panel held that Bolin did not show that the California
    Supreme Court’s denial of his claim that his trial counsel was
    ineffective in failing to renew the change of venue motion
    after jury selection was an unreasonable application of
    Strickland v. Washington. The panel held that reasonable
    jurists could conclude that Bolin could not overcome the
    strong presumption that his counsel acted reasonably and
    appropriately in failing to renew the motion based on pretrial
    publicity, including episodes of America’s Most Wanted.
    Bolin did not show that it would be objectively unreasonable
    for the state court to conclude that counsel could, as a matter
    of strategy, forego a likely quixotic change of venue motion
    in exchange for trying to secure a jury that would be more
    favorable to Bolin.

    BOLIN V. DAVIS                        3
    In connection with Bolin’s claim that his counsel acted
    ineffectively in not seeking a further continuance to develop
    additional mitigating evidence for the penalty phase, the
    panel granted Bolin’s request to expend the certificate of
    appealability to include the entirety of his claim of
    ineffective assistance in counsel’s failure to investigate and
    prepare for the penalty phase. The panel held that Bolin was
    not entitled to relief under Strickland for counsel’s
    investigation and presentation of mitigating evidence at the
    penalty phase or for counsel’s related determination not to
    seek a further continuance. Assuming without deciding that
    counsel’s performance was constitutionally defective, the
    panel held that Bolin could not show prejudice under
    AEDPA’s deferential standard of review. That is, a
    fairminded jurist could reasonably conclude that the further
    investigation and presentation of mitigating evidence Bolin
    claimed should have occurred was not substantially likely to
    change the outcome. The panel concluded that the
    mitigating evidence that Bolin claimed his counsel should
    have discovered and presented was either cumulative of
    other evidence that counsel did present, or was inconclusive
    and insufficiently compelling. Further, a reasonable jurist
    could also conclude that the new mitigating evidence did not
    overcome the serious aggravating factors associated with
    Bolin’s crimes and his history of violent criminal conduct.

    OPINION
    BRESS, Circuit Judge:
    A California jury convicted Paul Bolin of two counts of
    first-degree murder and he was sentenced to death. Bolin
    now seeks federal habeas relief, arguing that his trial counsel
    was ineffective in not renewing a motion to change venue
    and in failing to develop additional mitigating evidence.
    Applying the deferential standards of review in the
    Antiterrorism and Effective Death Penalty Act of 1996
    (AEDPA), we hold that Bolin is not entitled to relief.
    I
    A
    On Labor Day weekend in 1989, Paul Bolin shot three
    men, killing two of them. Bolin killed one man as he pleaded
    for his life in the fetal position. He shot the other man’s
    motionless body with a second firearm and staged the scene
    to make the murders look like a drug deal gone bad. When
    his third victim escaped, Bolin disabled the man’s truck and
    left him to die in a secluded area of the Sierra Nevada
    foothills. Given the testimony of two eyewitnesses, the
    events were not in significant dispute. We now summarize
    the facts based on the record before us and the California
    Supreme Court’s decision on Bolin’s direct appeal. See
    People v. Bolin, 
    956 P.2d 374
     (Cal. 1998).
    BOLIN V. DAVIS                        5
    In 1989, Bolin was living in a cabin in a remote,
    mountainous part of Walker Basin in Kern County,
    California. Vance Huffstuttler lived on the property in a
    trailer and assisted Bolin in growing marijuana there. Steve
    Mincy and Jim Wilson were spending their Labor Day
    weekend with family and friends at a campsite that Mincy’s
    father owned in the vicinity. On the Saturday, Mincy and
    Wilson went to a local bar and were drinking there with a
    group of people that included Huffstuttler and Bolin.
    Sometime after Bolin returned to his cabin, Wilson agreed
    to drive Huffstuttler back to his trailer. Mincy went along
    for the ride. Tragically, that decision would prove fateful.
    When the trio arrived at the cabin, they saw Bolin there
    with his friend Eloy Ramirez. Huffstuttler took Wilson and
    Mincy across a creek bed by the cabin to show them a patch
    of marijuana plants he and Bolin were cultivating. Bolin
    then became agitated. He followed the three men across the
    creek bed and confronted Huffstuttler about bringing
    outsiders to see the marijuana grow operation.
    According to Wilson, who testified at Bolin’s trial, Bolin
    and Huffstuttler crossed back over to the other side of the
    creek bed, heading toward the cabin and leaving Wilson’s
    view. Then Wilson heard a gunshot from that direction. A
    moment later, Bolin “came out from behind the tree line with
    a gun [a revolver] in his hand.” He “started apologizing to”
    Wilson and Mincy, and said, “I have got nothing against you
    guys, . . . but.” When Bolin said “but,” Wilson turned and
    ran. As he turned, Bolin shot him in the shoulder. Wilson
    ducked behind a tree.
    From behind the tree, Wilson heard Bolin shoot Mincy.
    Wilson could hear Mincy pleading with Bolin, saying, “no,
    please don’t. You don’t have to do this. Please don’t.”
    6                     BOLIN V. DAVIS
    Wilson then heard several more gunshots ring out. Staying
    hidden behind trees, Wilson ran away up and over a hill.
    Ramirez confirmed Wilson’s testimony and provided
    additional details for the jury. Ramirez testified that once
    Wilson had fled, Bolin retrieved a rifle he kept by his bed.
    Using the rifle, Bolin shot Huffstuttler’s inert body several
    times as he lay collapsed on the ground. Then, Bolin
    searched for Wilson after he escaped wounded into the
    forest; when he could not find him, Bolin commented to
    Ramirez that Wilson “would bleed to death” before he got
    off the hill.
    After shooting Huffstuttler and Mincy, Bolin told
    Ramirez that he was going to make the scene “look like a
    bad dope deal.” Bolin broke bottles and poured both
    marijuana and what Ramirez thought was chili on the dead
    bodies. Bolin placed the revolver in Huffstuttler’s dead
    hand. Bolin also disabled Wilson’s truck by removing wires
    and throwing them in a gully. Bolin and Ramirez then fled
    for southern California.
    Later analysis revealed that Mincy was shot four times,
    once while he was upright and three more times while he was
    in the fetal position lying in the creek bed. Huffstuttler was
    also shot four times. Wilson, who had traveled all night
    through the remote, mountainous area, managed to survive
    after finding refuge in a nearby ranch.
    Law enforcement found Ramirez at his girlfriend’s
    house in southern California shortly after the killings. But
    they were unable to find Bolin for several months. Finally,
    after the television program America’s Most Wanted
    featured a reenactment of Bolin’s murders, one of Bolin’s
    family members alerted the police that Bolin was staying in
    Chicago. That led to Bolin’s arrest.
    BOLIN V. DAVIS                        7
    As discussed further below, Bolin had a history of
    violent crime. In addition to domestic violence incidents
    during the 1970s, in 1983 a California jury convicted Bolin
    of attempted voluntary manslaughter for shooting his
    goddaughter’s then-boyfriend, Kenneth Ross, in the chest.
    Bolin was sent to state prison and paroled in May 1985. In
    January 1986, Bolin was arrested in Oklahoma for stabbing
    Jack Baxter. A jury acquitted Bolin based on Bolin’s claim
    of self-defense, but California still revoked his parole. Bolin
    was released from prison in March 1987.
    Then, on September 2, 1989, Bolin murdered
    Huffstuttler and Mincy. Since shooting Ross in 1981, up
    until the day he murdered Huffstuttler and Mincy in 1989,
    Bolin was out of custody for less than forty months.
    B
    Bolin was charged in Kern County Superior Court with
    two counts of first-degree murder, one count of attempted
    murder, and cultivation of marijuana. Bolin was eligible for
    the death penalty because the state tried him for multiple
    murders. See 
    Cal. Penal Code § 190.2
    (a)(3).
    The state trial court appointed Charles Soria as Bolin’s
    lead counsel and William Cater as second chair. Soria and
    Cater were both experienced attorneys. Soria had worked as
    a criminal defense lawyer in Kern County for almost a
    decade, and in that time he served as counsel in
    approximately fifteen murder cases, three of which were
    capital cases. Cater had served in the local public defender’s
    office and defended “lots of cases” before entering private
    practice. He had also tried two other capital cases. Cater
    was familiar with the California Death Penalty Defense
    Manual, and he had attended the Capital Case Defense
    Seminar at least twice.
    8                      BOLIN V. DAVIS
    Defense counsel initially filed a motion to change venue
    due to allegedly prejudicial pretrial publicity. This motion
    was largely based on the America’s Most Wanted
    reenactment. The trial court reserved judgment on the
    motion to see how this issue came up in voir dire of potential
    jurors. Following jury selection, defense counsel did not
    renew the change of venue motion. This issue is the basis
    for one of Bolin’s claims of ineffective assistance of counsel,
    and we provide more background on it below.
    On December 12, 1990, the jury found Bolin guilty on
    all charges. The following day, after the guilt phase closed,
    Bolin expressed unhappiness with his lead counsel, Soria.
    The trial judge granted Bolin’s request to remove Soria
    under People v. Marsden, 
    465 P.2d 44
     (Cal. 1970), based on
    a breakdown in the attorney-client relationship. With
    Bolin’s agreement and at his request, the trial judge
    appointed Cater to handle the penalty phase.
    On December 14, 1990, the judge granted a continuance
    until January 7, 1991 to give Cater more time to prepare
    Bolin’s penalty phase defense. On January 7, 1991, Cater
    requested and received another two-week extension. The
    penalty phase began on January 22, 1991. The jury in the
    penalty phase was the same jury that had convicted Bolin
    during the guilt phase.
    The jury returned a death verdict on January 24, 1991.
    We discuss at greater length below Cater’s investigation into
    Bolin’s mitigating circumstances and his presentation of
    mitigating evidence, which forms the basis for Bolin’s other
    ineffective assistance of counsel claim.
    The California Supreme Court affirmed Bolin’s
    convictions and sentence on direct appeal. Bolin, 956 P.2d
    BOLIN V. DAVIS                       9
    at 348. The United States Supreme Court then denied
    certiorari. Bolin v. California, 
    526 U.S. 1006
     (1999) (mem.).
    C
    Bolin filed state and federal habeas petitions on August
    8, 2000. His federal habeas petition was held in abeyance
    through completion of his state habeas proceedings. In his
    state habeas petition, Bolin asserted numerous claims,
    including the two ineffective assistance claims now before
    us.
    In his state habeas proceedings, Bolin did not submit
    declarations from trial counsel, nor did he submit a
    declaration on his own behalf. But he did come forward with
    some additional evidence, including: a declaration from
    Dr. Zakee Matthews, M.D., a psychiatrist who evaluated
    Bolin in 1999 and 2000; a declaration from Dr. Natasha
    Khazanov, Ph.D., a clinical psychologist who evaluated
    Bolin in 2000; the pretrial report of Dr. Ronald Markman,
    M.D., a forensic psychiatrist who evaluated Bolin in 1990;
    reports from Roger Ruby, Bolin’s investigator for the
    penalty phase; declarations from family members and a
    friend; and a letter Bolin sent to Jerry Halfacre, Bolin’s
    daughter’s former boyfriend. The California Supreme Court
    summarily denied Bolin’s state habeas petition “on the
    merits.”
    Bolin then filed an amended federal habeas petition. In
    support, Bolin included 51 exhibits that he had used to
    support his state habeas petition. Bolin also requested an
    evidentiary hearing on numerous claims. On April 27, 2012,
    the district court granted a hearing on Claim C2, regarding
    Bolin’s counsel not renewing the change of venue motion
    based on pretrial publicity. The district court held the
    evidentiary hearing on May 14, 2013.
    10                      BOLIN V. DAVIS
    On June 9, 2016, the district court denied all of Bolin’s
    claims, most of which are not at issue here, in a 305-page
    ruling. The district court issued a certificate of appealability
    on four claims:
    Claim C2: whether trial counsel was
    ineffective for failing to renew the change of
    venue motion following voir dire of the jury.
    Claim I13: whether trial counsel was
    ineffective because of irregularities and
    improprieties that occurred during the jury’s
    view of the crime scene and related locations.
    Claim L (L1–L4): whether the jury view of
    the crime scene violated [Bolin’s] state and
    federal rights.
    Claim W2: whether trial counsel was
    ineffective by failing to move for a further
    continuance at the penalty phase.
    In this court, Bolin presses only two of the four certified
    claims—Claims C2 and W2. 1 He does not argue Claims I13
    and L, thus abandoning them. See, e.g., Styers v. Schriro,
    
    547 F.3d 1026
    , 1028 n.3 (9th Cir. 2008) (per curiam). Bolin
    also seeks a certificate of appealability on two additional
    claims.

    lettering conventions used in the district court.

    II
    We review a district court’s denial of a 
    28 U.S.C. § 2254
    petition de novo. Cain v. Chappell, 
    870 F.3d 1003
    , 1012
    (9th Cir. 2017).
    Bolin claims that his counsel violated his Sixth
    Amendment rights by providing ineffective assistance. The
    Supreme Court’s decision in Strickland v. Washington,
    
    466 U.S. 668
     (1984), provides the established federal law
    governing ineffective assistance of counsel claims. To
    prevail on such a claim, a petitioner needs to “show both that
    his counsel provided deficient assistance and that there was
    prejudice as a result.” Harrington v. Richter, 
    562 U.S. 86
    ,
    104 (2011).
    Under Strickland’s performance prong, “[a] convicted
    defendant making a claim of ineffective assistance must
    identify the acts or omissions of counsel that are alleged not
    to have been the result of reasonable professional judgment.”
    Strickland, 
    466 U.S. at 690
    . We “must then determine
    whether, in light of all the circumstances, the identified acts
    or omissions were outside the wide range of professionally
    competent assistance.” 
    Id.
     We evaluate whether “counsel’s
    representation fell below an objective standard of
    reasonableness.” Richter, 
    562 U.S. at 104
     (quoting
    Strickland, 
    466 U.S. at 688
    ).             “Representation is
    constitutionally ineffective only if it ‘so undermined the
    proper functioning of the adversarial process’ that the
    defendant was denied a fair trial.” Id. at 110 (quoting
    Strickland, 
    466 U.S. at 686
    ).
    In evaluating counsel’s performance after the fact, we
    must also be careful to “apply the strong presumption of
    competence that Strickland mandates,” Cullen v. Pinholster,
    
    563 U.S. 170
    , 196 (2011), namely, that “counsel’s conduct
    12                     BOLIN V. DAVIS
    falls within the wide range of reasonable professional
    assistance,” Strickland, 
    466 U.S. at 689
    . We are required not
    only to give Bolin’s attorneys the benefit of the doubt, but to
    consider the possible reasons they may have had for their
    decisions. See Pinholster, 
    563 U.S. at 196
    . Strickland
    applies to counsel’s decisions in the penalty phase of a
    capital case. “Under Strickland, ‘counsel has a duty to make
    reasonable investigations or to make a reasonable decision
    that makes particular investigations unnecessary’ during the
    penalty phase of a trial.” Carter v. Davis, 
    946 F.3d 489
    , 513
    (9th Cir. 2019) (per curiam) (emphasis in original) (quoting
    Strickland, 
    466 U.S. at 691
    ).
    Bolin also bears the burden of showing that counsel’s
    ineffective performance prejudiced him. To make that
    showing, Bolin must first demonstrate that “there is a
    reasonable probability that, but for counsel’s unprofessional
    errors, the result of the proceeding would have been
    different.” Strickland, 
    466 U.S. at 694
    . “In the capital
    sentencing context, the prejudice inquiry asks ‘whether there
    is a reasonable probability that, absent the errors, the
    sentencer—including an appellate court, to the extent it
    independently reweighs the evidence—would have
    concluded that the balance of aggravating and mitigating
    circumstances did not warrant death.’” Shinn v. Kayer,
    
    141 S. Ct. 517
    , 522–23 (2020) (per curiam) (quoting
    Strickland, 
    466 U.S. at 695
    ). This standard is “highly
    demanding.” Id. at 523 (quoting Kimmelman v. Morrison,
    
    477 U.S. 365
    , 382 (1986)). It requires showing a
    “‘substantial,’ not just ‘conceivable,’ likelihood of a
    different result.” 
    Id.
     (quoting Pinholster, 
    563 U.S. at 189
    ).
    Moreover, Bolin’s Strickland claims must be evaluated
    under AEDPA’s additionally deferential standard of review
    because he filed his § 2254 petition after AEDPA’s effective
    BOLIN V. DAVIS                       13
    date. See, e.g., Woodford v. Garceau, 
    538 U.S. 202
    , 207
    (2003). Although the California Supreme Court’s denial of
    state habeas relief consisted of a summary denial on the
    merits, that decision must still be reviewed under AEDPA.
    See Richter, 
    562 U.S. at 98
     (“[D]etermining whether a state
    court’s decision resulted from an unreasonable legal or
    factual conclusion does not require that there be an opinion
    from the state court explaining the state court’s reasoning.”).
    AEDPA substantially constrains our review of Bolin’s
    claims. Under AEDPA,
    [a]n application for a writ of habeas corpus
    on behalf of a person in custody pursuant to
    the judgment of a State court shall not be
    granted with respect to any claim that was
    adjudicated on the merits in State court
    proceedings unless the adjudication of the
    claim—
    (1) resulted in a decision that was
    contrary to, or involved an unreasonable
    application of, clearly established Federal
    law, as determined by the Supreme Court
    of the United States; or
    (2) resulted in a decision that was based
    on an unreasonable determination of the
    facts in light of the evidence presented in
    the State court proceeding.
    
    28 U.S.C. § 2254
    (d).
    This is a challenging standard to meet. To satisfy
    AEDPA’s “unreasonable application of” prong, a petitioner
    “must show far more than that the state court’s decision was
    14                         BOLIN V. DAVIS
    ‘merely wrong’ or ‘even clear error.’” Kayer, 141 S. Ct.
    at 523 (quoting Virginia v. LeBlanc, 
    137 S. Ct. 1726
    , 1728
    (2017) (per curiam)). Instead, “[t]he prisoner must show that
    the state court’s decision is so obviously wrong that its error
    lies ‘beyond any possibility for fairminded disagreement.’”
    
    Id.
     (quoting Richter, 
    562 U.S. at 103
    ). That is, the state
    court’s application of clearly established federal law “must
    be objectively unreasonable.” Lockyer v. Andrade, 
    538 U.S. 63
    , 75 (2003).
    When, as here, the California Supreme Court did not
    offer reasoning when denying Bolin’s state habeas petition
    on the merits, “the habeas petitioner’s burden still must be
    met by showing there was no reasonable basis for the state
    court to deny relief.” Richter, 
    562 U.S. at 98
    . In that
    circumstance, we “must determine what arguments or
    theories . . . could have supported[] the state court’s
    decision; and then [we] must ask whether it is possible
    fairminded jurists could disagree that those arguments or
    theories are inconsistent with the holding in a prior decision
    of [the Supreme] Court.” 
    Id. at 102
    . 2
    We will address Bolin’s claims in the order in which they
    arose in the guilt and penalty phases. We thus begin with
    the motion to change venue. We then turn to Bolin’s claim
    2
    Bolin insists that the California Supreme Court as a matter of state
    law accepted his allegations as true. But Bolin’s reliance on California
    pleading rules is inapposite, and his description of California law is in
    any event incomplete. See Pinholster, 
    563 U.S. at
    188 n.12 (explaining
    that while the California Supreme Court “generally assumes the
    allegations in the petition to be true,” it “does not accept wholly
    conclusory allegations” and “will also ‘review the record of the trial . . .
    to assess the merits of the petitioner’s claims’” (quoting In re Clark,
    
    855 P.2d 729
    , 742 (Cal. 1993)).
    BOLIN V. DAVIS                       15
    that his counsel failed to develop and present mitigating
    evidence.
    III
    In Claim C2, Bolin argues that his trial counsel was
    ineffective in failing to renew a change of venue motion after
    jury selection. We hold that under AEDPA, Bolin has not
    shown that the state court’s rejection of this claim was an
    unreasonable application of Strickland. We first set forth the
    relevant factual background for this claim. We then explain
    why under AEDPA, Bolin is not entitled to relief.
    A
    Before voir dire of prospective jurors, Bolin moved for a
    change of venue based on pretrial publicity that, in Bolin’s
    view, unfairly prejudiced the jury pool in Kern County.
    Besides his crime being featured on an episode of America’s
    Most Wanted and his later arrest being mentioned in a second
    episode, the local print and television media also had
    covered the murders. In connection with his venue motion,
    Bolin submitted videotapes of the America’s Most Wanted
    episodes and newspaper clippings. Bolin, 
    956 P.2d at 385
    .
    In particular, Bolin argued that the first episode of America’s
    Most Wanted included an inflammatory and misleading
    reenactment of his crimes.
    Bolin also submitted in connection with his motion
    results from a public opinion survey specific to Kern County
    that his counsel commissioned.          
    Id.
         His counsel
    “represented that 45 percent of the people responding
    indicated they had some knowledge of the case due to the
    media attention,” while approximately 20 percent of those
    respondents said they had seen the America’s Most Wanted
    reenactment. 
    Id.
    16                     BOLIN V. DAVIS
    The trial judge initially said he was “very, very
    concerned” about the America’s Most Wanted program. But
    the court also stated: “I’m not inclined to grant the motion to
    change venue.” The judge instead “reserve[d] ruling on” the
    venue motion, indicating that he wanted to see the responses
    given by potential jurors during voir dire. The court also
    “ma[d]e it perfectly clear, but for this reenactment on
    America’s Most Wanted, I do not think there are grounds to
    change the venue.” The trial court allowed, however, that it
    might consider granting requests to strike jurors for cause
    based on their reactions to the television program.
    In conducting voir dire, Bolin’s counsel asked jurors a
    variety of questions to get a sense of how they may react to
    the evidence, including prospective jurors’ likely
    perspectives on the death penalty and their exposure to the
    America’s Most Wanted episodes.              Bolin’s counsel
    challenged for cause every juror who had seen the America’s
    Most Wanted program. The trial court denied these requests.
    Bolin’s counsel did not use peremptory challenges on every
    juror who acknowledged having seen the show. Bolin’s
    counsel also did not renew the motion to change venue at the
    close of voir dire. The trial thus took place in Kern County,
    where the murders occurred.
    On direct appeal, Bolin asserted that counsel was
    incompetent for failing to renew the change of venue motion.
    The California Supreme Court rejected this argument
    because counsel’s decision “did not result from ignorance or
    inadvertence and reflected a reasonable trial strategy.”
    Bolin, 
    956 P.2d at 386
    . The pretrial publicity, especially
    from America’s Most Wanted, “was a critical focus of the
    voir dire.” 
    Id.
     And “[a]lthough many prospective jurors had
    been exposed to some pretrial publicity, including the
    segment reenacting the killings, for the most part few
    BOLIN V. DAVIS                             17
    recalled the specifics or had formed a resolute impression of
    defendant’s guilt.” 
    Id.
     The court also found it relevant that
    the impaneled jurors “all gave assurances they would decide
    the case based solely on the courtroom evidence.” 
    Id.
    The California Supreme Court on direct appeal thus
    concluded that “counsel could well have recognized the
    effect of the publicity had not been as substantial as feared,
    especially after an 11-month interim.” 
    Id.
     at 386–87. This
    made renewing the venue motion “futile” because the trial
    court had indicated a willingness to reconsider its tentative
    denial of the motion only on a showing that an impartial jury
    could not be seated. 
    Id. at 387
    . Bolin then reasserted this
    ineffective assistance claim again in his state and federal
    habeas petitions. 3
    B
    The California Supreme Court’s rejection of Bolin’s
    ineffective assistance Claim C2 was not objectively
    unreasonable. Instead, fairminded jurists could conclude
    that Bolin’s counsel was not deficient.
    3
    The district court held an evidentiary hearing on Claim C2, which
    included testimony from Cater and Soria. In Pinholster, however, the
    Supreme Court clarified that “review under § 2254(d)(1) is limited to the
    record that was before the state court that adjudicated the claim on the
    merits.” 
    563 U.S. at 181
    . In other words, “evidence later introduced in
    federal court is irrelevant to § 2254(d)(1) review.” Id. at 184; see also
    id. at 203 n.20 (“We are barred from considering the evidence Pinholster
    submitted in the District Court that he contends additionally supports his
    claim.”). We thus limit our discussion to the record before the state
    habeas court. We note, however, that the result would be the same even
    if we were to consider the additional evidence developed in connection
    with the federal evidentiary hearing.
    18                     BOLIN V. DAVIS
    Under Strickland’s performance prong, “counsel should
    be ‘strongly presumed to have rendered adequate assistance
    and made all significant decisions in the exercise of
    reasonable professional judgment.’” Pinholster, 
    563 U.S. at 189
     (quoting Strickland, 
    466 U.S. at 690
    ). This means
    that “[e]ven under de novo review, the standard for judging
    counsel’s representation is a most deferential one.” Richter,
    
    562 U.S. at 105
    . But with AEDPA’s overlay, our review is
    even more forgiving: “[t]he standards created by Strickland
    and § 2254(d) are both ‘highly deferential,’ and when the
    two apply in tandem, review is ‘doubly’ so.” Id. (citations
    omitted) (first quoting Strickland, 
    466 U.S. at 689
    ; and then
    quoting Knowles v. Mirzayance, 
    556 U.S. 111
    , 123 (2009)).
    In this case, reasonable jurists could conclude that Bolin
    cannot overcome the strong presumption that his counsel
    acted reasonably and appropriately in not renewing the
    change of venue motion. That is because counsel could have
    concluded that the motion stood little chance of success and
    that using peremptory strikes on jurors only to support this
    likely futile motion would result in striking jurors potentially
    favorable to Bolin.
    In evaluating change of venue motions, California courts
    consider “the gravity and nature of the crime or crimes, the
    extent and nature of the pretrial publicity, the size and nature
    of the community, the status of the victim, the status of the
    accused, and any indication from the voir dire of prospective
    and actual jurors that the publicity did in fact have a
    prejudicial effect.” People v. Coleman, 
    768 P.2d 32
    , 41–42
    (Cal. 1989). Even before the trial court’s skeptical
    comments on the motion to change venue, Bolin faced an
    uphill battle under the governing legal standards.
    Although the crimes were sensational, there is no
    indication Bolin or the victims were well-known in the
    BOLIN V. DAVIS                       19
    community. Kern County’s size, perhaps the most important
    factor in California’s change of venue cases, also weighed
    heavily against Bolin. See People v. Balderas, 
    711 P.2d 480
    ,
    497–98 (Cal. 1985) (“Kern County, with a 1981 population
    of 405,600, ranked 14th among California’s 58 counties in
    that respect. Cases in which venue changes were granted or
    ordered on review have usually involved counties with much
    smaller populations.” (citation omitted)). In addition, the
    America’s Most Wanted broadcast was some time in the past
    by the time of jury selection. See Coleman, 
    768 P.2d at 43
    (“The publicity did not pervade the proceedings so as to give
    rise to any inference or presumption of prejudice.”).
    Bolin’s counsel also could have taken cues from the trial
    court when it initially reserved ruling on the change of venue
    motion. Although the trial court had expressed concern
    about the America’s Most Wanted episodes, it also indicated
    it was not inclined to grant the motion. The court wanted to
    see how potential jurors responded to the issue in voir dire,
    while making clear that the television show was the only
    possible basis for changing venue.
    But voir dire all but confirmed that any renewed venue
    motion would fail. Compared to the survey results counsel
    had commissioned, a similar percentage of jurors at voir dire
    indicated they had seen or believed they may have seen the
    America’s Most Wanted program. But voir dire revealed that
    those respondents did not necessarily remember much, if
    anything, of the program a year later. Jurors also gave
    credible assurances that they would decide the case based
    only on the evidence presented in court, not based on the
    reenactment. Having observed the voir dire, the trial court
    denied defense counsel’s for-cause challenges to jurors that
    were based solely on jurors having acknowledged seeing the
    America’s Most Wanted episode. As the district court
    20                     BOLIN V. DAVIS
    reasoned, “it is unlikely that a trial judge who may have just
    denied a challenge to a juror for cause based on prejudice
    stemming from publicity will grant a motion to change
    venue a short time later.” (quoting Jeffrey G. Adachi et al.,
    California Criminal Law Procedure and Practice § 15.17
    (2013)).
    Renewing the change of venue motion also carried
    considerable risks as well. Under California law, counsel’s
    failure to exhaust all their peremptory challenges is at the
    very least a “significant” factor supporting the denial of a
    renewed motion to change venue. Coleman, 
    768 P.2d at
    43–
    44; see also People v. Sommerhalder, 
    508 P.2d 289
    , 297–98
    (Cal. 1973). Without having exercised all available
    peremptory challenges, the change of venue motion, if
    renewed, would have had a limited prospect of success. But
    using all of Bolin’s peremptory challenges would have
    meant striking jurors that counsel thought could be favorable
    to Bolin, including jurors perceived as less likely to vote for
    the death penalty. Especially when the venue motion was
    unlikely to succeed, Bolin’s experienced counsel could have
    decided that knocking out potentially favorable jurors was
    not a wise strategy. Under AEDPA, Bolin’s defense lawyers
    were not required to pursue a change of venue motion at all
    costs.
    Much of Bolin’s briefing has less to do with whether his
    counsel were constitutionally ineffective by not renewing
    the motion for a change of venue. Instead, Bolin’s opening
    brief primarily argues that “at the time voir dire began, no
    meaningful investigation had been undertaken. As a result,
    trial counsel had no knowledge of Mr. Bolin’s life
    experience and social history upon which to base strategic
    decisions regarding jurors.” Although this argument relates
    to voir dire, Bolin does not explain how it relates to the
    BOLIN V. DAVIS                       21
    change of venue motion or the America’s Most Wanted
    episodes. We explain below why, under AEDPA, Bolin has
    not shown that counsel’s investigation and presentation of
    mitigating circumstances prejudiced him. To the extent
    Bolin repackages that argument as support for Claim C2
    regarding the change of venue motion, it fails for the reasons
    we explain below.
    In short, Bolin has not shown that it would be objectively
    unreasonable for the state court to conclude that counsel
    could, as a matter of strategy, forego a likely quixotic change
    of venue motion in exchange for trying to secure a jury that
    would be more favorable to Bolin.
    IV
    We turn next to Claim W2, that Cater acted ineffectively
    in not seeking a further continuance to develop additional
    mitigating evidence for the penalty phase. Within this
    certified claim, the parties have briefed the broader question
    of whether trial counsel conducted an inadequate
    investigation into mitigating circumstances.
    In connection with Claim W2, Bolin also asks us to
    expand the certificate of appealability to include the entirety
    of Claim W. See 
    28 U.S.C. § 2253
    (c)(2); Ninth Cir. R.
    22-1(d), (e). Claim W consists of counsel’s alleged
    “wholesale failure to investigate and prepare for” the penalty
    phase. Because of the nature of Claim W2, Bolin’s
    arguments under Claims W and W2 largely overlap. And
    the State’s briefing of Claim W2 is already responsive to
    Bolin’s request for an expanded certificate of appealability
    on Claim W. We grant Bolin’s request to expand the
    certificate of appealability to include Claim W, to the extent
    of Bolin addressing Claim W in his opening brief. See White
    22                          BOLIN V. DAVIS
    v. Ryan, 
    895 F.3d 641
    , 645 n.1 (9th Cir. 2018) (citing
    Browning v. Baker, 
    875 F.3d 444
    , 471 (9th Cir. 2017)). 4
    We hold that under AEDPA’s deferential standard of
    review, Bolin has not shown he is entitled to relief under
    Strickland for counsel’s investigation and presentation of
    mitigating evidence at the penalty phase or for counsel’s
    related determination not to seek a further continuance.
    Although we question whether Bolin could make the
    required showing given Cater’s substantial efforts to develop
    mitigating evidence, we will assume without deciding that
    Cater’s performance was constitutionally deficient (and that
    under AEDPA, no reasonable jurist could conclude
    otherwise). Even so, Bolin cannot show prejudice under
    AEDPA’s deferential standard of review. That is, a
    fairminded jurist could reasonably conclude that the further
    investigation and presentation of mitigating evidence Bolin
    claims should have occurred was not substantially likely to
    4
    Claim W also includes subparts that Bolin has not briefed. For
    example, Claim W8 relates to alleged ineffectiveness in not objecting to
    certain penalty phase jury instructions. By not raising these arguments
    in his opening brief, Bolin has forfeited them. See Floyd v. Filson,
    
    949 F.3d 1128
    , 1138 n.2 (9th Cir.), cert. denied, 
    141 S. Ct. 660
     (2020);
    Ninth Cir. R. 22-1(e).
    We also deny Bolin’s request to expand the certificate of
    appealability to include whether we should remand under Martinez v.
    Ryan, 
    566 U.S. 1
     (2012). Martinez held that “[i]nadequate assistance of
    counsel at initial-review collateral proceedings may establish cause for a
    prisoner’s procedural default of a claim of ineffective assistance at trial.”
    
    Id. at 9
    . Bolin has not demonstrated that Martinez is relevant here or that
    he would be entitled to relief under it. Thus, Bolin has not made a
    “substantial showing of the denial of a constitutional right.” 
    28 U.S.C. § 2253
    (c)(2); see also Miller-El v. Cockrell, 
    537 U.S. 322
    , 327 (2003).
    BOLIN V. DAVIS                      23
    change the outcome. See, e.g., Kayer, 141 S. Ct. at 522–23;
    Pinholster, 
    563 U.S. at
    197–98.
    To explain this holding, it is necessary first to recount
    Cater’s investigation of mitigating evidence. Next, we
    discuss the penalty phase presentations that both sides made
    to the jury. We then examine the additional mitigating
    evidence that Bolin claims his counsel should have
    discovered and presented. As we will explain, that
    mitigating evidence either is cumulative of other evidence
    that counsel did present, or it is inconclusive and
    insufficiently compelling. A reasonable jurist could also
    conclude that the new mitigating evidence does not
    overcome the serious aggravating factors associated with
    Bolin’s crimes and his history of violent criminal conduct.
    Considered as a whole, the record thus shows that at the
    very least, under AEDPA, Bolin cannot establish Strickland
    prejudice based on Cater’s alleged failure to develop
    additional mitigating evidence and to seek a further
    continuance for that purpose.
    A
    1
    We start with Cater’s investigation of mitigating
    evidence. When the trial judge on December 14, 1990
    granted Bolin’s motion to have Soria removed as counsel,
    Cater was appointed lead counsel for the penalty phase. At
    that hearing, Cater said that he was “quite familiar with the
    case, obviously, and somewhat prepared and very much
    acquainted with the theory of the death penalty
    presentation,” so he thought he could be ready by January 7,
    1991. Thus, the judge granted Cater a continuance of three
    and a half weeks. On January 7, 1991, after Cater expressed
    24                    BOLIN V. DAVIS
    dissatisfaction with the investigatory work done by Soria and
    Soria’s investigator, Bruce Binns, Cater requested and
    received another two-week continuance.
    Among the more significant documents that Cater
    received from Soria was a report from Dr. Ronald Markman,
    who had conducted a psychiatric evaluation of Bolin at
    Soria’s direction. Dr. Markman had conducted that
    evaluation on September 22, 1990, and he sent a written
    report to Soria on November 12, 1990.
    Dr. Markman diagnosed Bolin with polysubstance
    dependence and a personality disorder with paranoid,
    explosive, and antisocial features. But Dr. Markman’s
    “examination revealed [Bolin] to be fully oriented in all
    spheres, alert, cooperative and of above normal intelligence
    with an excellent fund of knowledge.” Dr. Markman also
    wrote that “[t]here was no evidence of a major mental
    diso[r]der, thought disorder or psychosis, judgment was not
    impaired and insight into his status was adequate.” The
    report contains some background life history on Bolin while
    noting that Bolin was unwilling to provide much
    information.
    Dr. Markman reported that Bolin had “no history of
    previous psychiatric treatment or hospitalization.” Bolin
    “admit[ted] to poly-drug abuse ‘years ago—you name it,’ to
    include intravenous heroin and cocaine.” He also had “an
    extended history of daily alcohol use.” Bolin reported to
    Dr. Markman that he had “consumed a substantial amount of
    alcohol, both beer and bourbon ‘to calm my nerves’ and
    smoked cocaine prior” to killing Huffstuttler and Mincy.
    Dr. Markman’s report also discusses Bolin’s “extensive and
    repeated history of aggressive behavior,” including Bolin’s
    prior convictions.
    BOLIN V. DAVIS                       25
    When he spoke with Dr. Markman, Bolin claimed he was
    injured in Vietnam when his boat was hit by a “rocket.”
    Dr. Markman noted that this claim had “not been
    corroborated” and that Bolin’s claims about his injury and
    subsequent discharge were “highly unusual.” (In a much
    more detailed account of Bolin’s time in Vietnam prepared
    for the state habeas proceedings, Dr. Matthews did not
    mention that Bolin was injured in the conflict. Dr. Matthews
    did report, however, that when Bolin was later stationed in
    San Diego, he seriously injured his back while working on a
    ship.)
    When it came to other investigative reports and work
    product, however, Cater determined that the record was
    lacking. Cater thus undertook substantial efforts to
    investigate mitigating circumstances that he could raise on
    Bolin’s behalf. Within two days of Cater being appointed as
    sole counsel, he and Ruby went to interview Bolin in jail.
    Bolin told them that he had behaved well when he had been
    incarcerated previously and had received several
    commendations from the prison for maintenance work he
    had done.
    When Cater requested a two-week continuance at the
    January 7, 1991 hearing, Cater told the judge that he had
    made good progress on the investigation. Ruby had
    “practically closed down his office” and was “working full
    time” investigating Bolin’s life history. By that time, Ruby
    had already traveled to Oklahoma, Chicago, Arizona, and
    several places in California to meet with potential witnesses.
    Among others, Ruby spoke to Mary and Paula (Bolin’s
    daughters), Pamela Castillo (Bolin’s stepdaughter), Fran and
    Rosemary (Bolin’s sisters), and various other relatives,
    including Gary Monto (cousin), Marilyn Perez (cousin),
    Trina Perez (Marilyn’s daughter), Florence Monto (Gary’s
    26                    BOLIN V. DAVIS
    wife), Betty Monto (aunt), Jeremiah Monto (Gary and
    Florence’s son), Sylvester Monto (uncle), and David
    Alexander (Bolin’s probation officer in Oklahoma). After
    the hearing, Ruby (with Cater) went to southern California
    as part of the investigation. These various meetings yielded
    considerable information about Bolin’s background and
    upbringing.
    In Chicago in particular, Bolin’s sisters and other
    relatives “gave [Ruby] a wealth of information on [Bolin’s]
    background,” and Ruby determined that several relatives
    would be appropriate witnesses. Ruby learned of the
    family’s claims that Bolin’s childhood included physical
    abuse at the hands of his father William Bolin, and that Bolin
    spent time bouncing from place to place, including time
    living on the streets when he was nine or ten years old.
    According to Ruby’s notes, Bolin’s sister Fran told Ruby
    that when they were growing up, their “father would beat
    them for nothing.” After their parents divorced, Bolin tried
    living with his father and stepmother. This did not work out
    because the stepsiblings would blame Bolin for anything
    they did wrong, and Bolin’s father “would then beat Paul
    until the dad could no longer raise his arms.”
    Fran did not remember Bolin ever needing to go to a
    hospital but relayed that one time their father had “hit him
    and knocked him into the wall,” and that Bolin “was out for
    over an hour from the blow.” Bolin “never tried to fight
    back, he finally just left home and lived from place to place
    [wherever] he could. Most of the time the grandmother
    raised him or at least tried to.” According to Ruby’s notes,
    Fran said that Bolin “became an orphan on the streets at age
    10 and his first ten years were a living hell.”
    BOLIN V. DAVIS                       27
    Rosemary, Bolin’s other sister, also told Ruby that her
    father had physically abused the children and their mother.
    Rosemary claimed that her father once tried to stab her
    mother in front of the children. She also recalled that her
    father beat her with a leather strap, and, as a result, she had
    trouble with her legs as an adult. Rosemary recalled that
    Bolin “went to the streets at about age 9.” He moved from
    place to place but mostly lived with his grandmother. When
    he would try to return home, it ended with Bolin being
    beaten by his father. Ruby concluded, however, that
    Rosemary likely would not make a good witness because she
    would “come across to the jury as one that is better than the
    rest of the family.” Rosemary also expressed some
    unwillingness to attend the proceedings due to her family
    obligations.
    Ruby further learned that Bolin’s living situation became
    more stable when he was fourteen and his mother married
    his stepfather, Jim. According to Fran, Jim wanted to “put
    the family back together.” The family moved around with
    some frequency. The family had been living in Salt Lake
    City for about a year when Bolin joined the military. Fran
    did not see Bolin much, if at all, until he came to Chicago
    after the murders.
    Other family members in Chicago conveyed to Ruby
    their positive recollections of Bolin. For example, Marilyn
    Perez, Bolin’s cousin, told Ruby that Bolin loved his family,
    and that Bolin had helped perform home renovations for her
    when he was in Chicago (after the murders). Marilyn’s
    daughter Trina discussed Vietnam with Bolin, and he told
    her that it was a “horr[i]d place and was not a place for any
    man to have to be.”
    From Pamela Castillo, Bolin’s stepdaughter, and Mary
    Bolin, Bolin’s daughter, Ruby obtained information about
    28                     BOLIN V. DAVIS
    Bolin’s role as a protective parent figure. When Mary was
    five and Bolin was serving in the Navy, Mary’s mother
    began a relationship with another man. She abandoned her
    two daughters, leaving it to friends and neighbors to care for
    them. Bolin eventually obtained custody of Mary and Paula.
    Ruby’s notes indicate that he also spoke with Paula as well.
    Ruby also learned how Bolin allowed Pamela to come and
    live with him after Pamela’s mother left the country for a
    new relationship.
    In southern California, Cater and Ruby talked to more
    than twice as many people as Binns, Soria’s investigator.
    They found “several important witnesses,” and they were
    evaluating whether to use them.

    The penalty phase began on January 22, 1991. In
    addition to emphasizing the murders for which the jury had
    already convicted Bolin, the State presented evidence of
    other incidents when Bolin engaged in violent and
    threatening conduct.
    The State first called Kenneth Ross, Bolin’s victim on
    his conviction for attempted voluntary manslaughter, for
    which Bolin was sentenced to five years in prison. Ross told
    the jury that in 1981, Bolin shot him in the chest while Ross
    was having an argument with Bolin’s goddaughter, Nyla
    Olson (now Nyla Ross, Kenneth’s wife). Ross testified that
    the shot Bolin fired “tore up my liver, punctured my
    diaphra[g]m, front and rear, went through my lung, broke my
    rib,” and that pieces of the bullet were still inside him. Bolin
    also beat Ross with his rifle after he shot him. As a result of
    this incident, Ross was hospitalized for several weeks. Nyla
    Ross also testified, and she confirmed that Kenneth was
    unarmed when Bolin shot him.
    BOLIN V. DAVIS                      29
    The State then put on Matthew Spencer. Spencer
    testified that in 1979, he and his friend Brian Martinez went
    over to Bolin’s house at the invitation of “Becky,” who was
    renting a room from Bolin. Bolin became upset at Spencer’s
    presence in the home and assaulted Spencer with help from
    a friend, Ricky Balsamico. Balsamico beat Spencer with a
    stick, and Bolin beat him with a pipe. Bolin was not charged
    for this conduct.
    The State also presented evidence that Bolin sent a
    threatening letter to his daughter Paula’s former boyfriend,
    Jerry Halfacre. In the letter, which Bolin sent while he was
    awaiting his double-murder trial, Bolin warned Halfacre that
    if he saw Bolin’s daughter again, Bolin would have him
    “permanently removed from the face of this Earth.”
    In her closing argument, the prosecutor emphasized
    Bolin’s callousness for his victims, his failure to take
    responsibility, and his gravitation toward violence. The
    prosecutor also reminded the jury of the crimes for which
    Bolin was convicted, reiterating Bolin’s heartlessness in the
    killings, including how he left Wilson to die in the
    mountains.
    3
    For the defense presentation at the penalty phase, Cater
    put on eight witnesses: Mary Bolin (Bolin’s daughter), Paula
    Halfacre (Bolin’s other daughter), Pamela Castillo (Bolin’s
    former stepdaughter), Nancy Belden (a correctional officer
    who had observed Bolin’s earlier behavior in prison), Fran
    Bolin (Bolin’s sister), Marilyn Perez (Bolin’s cousin), Trina
    Perez (Marilyn’s daughter), and Jeremiah Monto (Bolin’s
    first cousin once removed). Through these witnesses, Cater
    largely focused on eliciting Bolin’s positive attributes and
    redeeming qualities and how Bolin had helped his family.
    30                    BOLIN V. DAVIS
    But Cater also had witnesses touch on Bolin’s difficult
    upbringing and military service, albeit briefly, and the
    incidents of other violent crimes that the State had raised in
    aggravation.
    Bolin’s daughters, Mary and Paula, testified that Bolin
    took them in and cared for them as a single father after his
    first wife abandoned the girls while Bolin was serving in the
    Navy. Pamela Castillo, Bolin’s stepdaughter, similarly told
    the jury how Bolin had allowed her to live with him after her
    mother left the country, even though Bolin and Pamela’s
    mother were no longer married by that point. Pamela
    recalled how Bolin provided food, shelter, and money for the
    household, and how he also allowed Pamela’s friend, Nyla
    Olson (later Nyla Ross), to live at the home too. Paula and
    Pamela both noted Bolin’s positive relationships with their
    own children.
    Bolin’s daughters filled in other details about Bolin’s
    life. Paula explained the circumstances of Bolin coming to
    live in his remote mountain cabin, testifying that Bolin had
    relocated there after Bolin’s fiancée, Rhonda, died in a car
    accident. Mary testified about her father’s service in the
    Navy, including in Vietnam.
    Mary Bolin was the only defense witness to testify about
    the Spencer and Ross incidents. She claimed that Bolin was
    not the one to strike Spencer and that Bolin was trying to
    protect her because Spencer was trying to touch her
    inappropriately and was using drugs in the house. As to the
    Ross shooting, Mary testified that Kenneth Ross was acting
    violently toward Nyla and was carrying a stick as a weapon.
    (The prosecution later cross-examined Mary based on
    inconsistencies between her accounts of the incidents and the
    police reports.)
    BOLIN V. DAVIS                       31
    Bolin’s sister Fran, who is four years younger than Bolin,
    testified as well. Cater did not ask Fran about the physical
    abuse she had recounted to Ruby. Fran did, however, tell the
    jury some of Bolin’s life story. When their parents divorced
    (Fran was then four or five years old, and Bolin eight or
    nine), Fran went to live with their grandmother, but Bolin
    stayed with their father, William Bolin. Fran testified about
    the difficult relationships Bolin had with both William and
    Bolin’s first stepfather. She also spoke about the general
    hardship Bolin endured during his childhood, recalling that
    Bolin sometimes “lived with his friends on the street, in
    cars.”
    Fran and other Chicago relatives also emphasized
    Bolin’s good character, telling the jury how, after Bolin
    returned to Chicago following the murders, he tried to get
    family members to spend time together, took the lead on
    home renovation projects, and served as a mentor figure to
    younger family members. Nancy Belden, a correctional
    officer assigned to Bolin’s housing unit while he was
    incarcerated for shooting Kenneth Ross, recalled Bolin as a
    “cooperative inmate” and was unaware of him having caused
    problems in prison.
    In his closing argument, Cater argued that Bolin should
    be sentenced to life in prison. Cater focused on Bolin’s
    positive attributes, including his military service and how he
    provided for Mary, Paula, and Pamela after their mothers
    abandoned them: “This is not a man whose life is not without
    redemption. He provided a shelter, he provided food, he
    provided a home and a father to these children, and this is
    not a man that has sought out and gone and done things that
    you have [to] execute[] him for.”

    B
    Bolin’s principal claim on appeal is that Cater should
    have sought more time to develop mitigating evidence and
    that had he done so, Cater would have discovered new
    evidence that would have led the jury to sentence Bolin to
    life in prison instead of death. Under AEDPA, we are
    constrained to disagree. We hold that a reasonable jurist
    could conclude that a further continuance of the penalty
    phase, and Cater’s discovery and presentation of the
    additional mitigating evidence Bolin now identifies, was not
    reasonably likely to have changed the result in Bolin’s case.
    The reason lies in the “balance of aggravating and
    mitigating circumstances” that Bolin’s case presents.
    Strickland, 
    466 U.S. at 695
    ; see also Pinholster, 
    563 U.S. at 198
     (explaining that courts evaluating Strickland
    prejudice must “reweigh the evidence in aggravation against
    the totality of available mitigating evidence” (quoting
    Wiggins v. Smith, 
    539 U.S. 510
    , 534 (2003)). The new
    mitigating evidence that Bolin has developed in connection
    with his habeas petition is “hardly overwhelming.” Kayer,
    141 S. Ct. at 525 (quoting Kayer v. Ryan, 
    923 F.3d 692
    , 727
    (9th Cir. 2019) (Owens, J., dissenting)). Although that
    evidence presents Bolin in a more sympathetic light in some
    respects, it also suffers from a variety of shortcomings. At
    times, it is variously speculative, double-edged, ambiguous,
    or otherwise unpersuasive. In other instances, it is
    cumulative of evidence and mitigation themes that Cater had
    presented. Especially when compared to the “undisputedly
    strong aggravating factor[s],” 
    id.
     (quoting Kayer, 923 F.3d
    at 727 (Owens, J., dissenting)), a reasonable jurist could
    conclude that the claimed ineffective assistance of counsel
    during the penalty phase did not prejudice Bolin.
    BOLIN V. DAVIS                       33
    We first address the several areas of allegedly
    undeveloped mitigating evidence that Bolin identifies. We
    explain why, taken as a whole, they are insufficiently
    compelling. We then turn to the aggravating factors that the
    State presented.
    1
    Bolin argues that his counsel should have investigated
    and presented evidence that primarily consists of the
    following: (1) Bolin’s possible neurological deficits; (2) his
    substance abuse prior to the murders; (3) his traumatic
    childhood; (4) his military service, including his time in
    Vietnam; (5) his good character, based on Bolin’s role as a
    protective parent and his good behavior in prison; and
    (6) expert testimony to synthesize his life history. While we
    must necessarily address each of these areas individually,
    our ultimate conclusion turns not only on deficiencies within
    each category of mitigation evidence, but in all the
    mitigation theories when considered as a collective whole.
    Neurological deficits. Bolin claims that his counsel
    failed to inform the jury that Bolin had “neuropsychological
    dysfunction localized to the frontal lobes” of his brain, which
    Bolin attributes to “[h]is numerous head injuries, alcohol
    abuse, and exposure to neurotoxins on a daily basis for
    fifteen years, including solvents, petroleum products and
    lead particles.” According to Bolin, “[b]ecause his frontal
    lobes have been damaged, [he] has profound impairments in
    flexibility (the ability to shift or adapt thinking or behavior
    to changed circumstances) and the ability to inhibit
    unwanted responses.”
    The basis for this theory is the expert declarations of
    Drs. Khazanov and Matthews. Dr. Khazanov performed a
    neurological assessment on Bolin and concluded that Bolin
    34                     BOLIN V. DAVIS
    exhibited evidence of brain damage, which Dr. Khazanov
    attributed to potential head trauma from Bolin’s childhood,
    exposure to neurotoxins from his time in the Navy and his
    work as a pipefitter and welder, and his excessive
    consumption of alcohol. Dr. Khazanov opined that because
    of his brain damage, Bolin is “prone to confabulate and fill
    in the large gaps in his memory with incorrect information,”
    and is further “unable to adequately plan complex actions,
    learn from his mistakes, or . . . shift his thinking or behaviors
    in response to environmental or verbal cues.”
    In his separate report, Dr. Matthews relied on both
    Bolin’s life history, including childhood trauma and alleged
    neurotoxin exposure, and Dr. Khazanov’s conclusions, to
    opine      that     Bolin      “is    psychiatrically    and
    neuropsychologically impaired,” and that “such deficits
    were causally related to his behavior at the time of the
    offenses for which he has been sentenced to death.”
    Dr. Matthews echoed Dr. Khazanov’s determination that
    Bolin “has a tendency to confabulate” and that because of
    his brain damage, “he unintentionally fills in the gaps with
    misinformation.” Dr. Matthews concluded that based on
    Bolin’s impairments, “at the time of the crime [Bolin]
    became frightened and suddenly perceived great danger to
    himself in the actions of Vance Huffstuttler, which caused
    him to believe that he had to defend himself against that
    danger.”
    Drs. Khazanov and Matthews conducted their analyses
    approximately ten years after the murders. And their
    assessment of Bolin is largely at odds with the conclusions
    of Dr. Ronald Markman, who evaluated Bolin prior to trial
    and whose report (which Cater received) concluded that
    “[t]here was no evidence of a major mental disorder.” Even
    setting these points aside, there are a number of significant
    BOLIN V. DAVIS                       35
    shortcomings in Bolin’s neurological deficits theory. We
    need identify only some of them to show that a reasonable
    jurist could conclude that this theory lacks support and is
    thus unlikely to have affected the jury’s decision.
    As an initial matter, while Dr. Khazanov concluded that
    Bolin’s test results were consistent with brain injury, she
    acknowledged that Bolin’s medications, “underlying
    depression and anxiety,” and possible malingering could
    affect the results. More importantly, while Drs. Khazanov
    and Matthews tried to connect Bolin’s claimed neurological
    deficits to childhood trauma and neurotoxin exposure, that
    connection was speculative, or at least a reasonable jurist
    could so conclude. Cf. Leavitt v. Arave, 
    646 F.3d 605
    , 614
    (9th Cir. 2011) (“[S]peculative mitigation evidence is not
    entitled to significant weight.”).
    Dr. Khazanov suggested that Bolin may have developed
    brain injuries from his father’s abuse. But she based this on
    several scars on Bolin’s head, a “definite indentation” she
    identified near a scar site, and one incident in which Bolin’s
    father allegedly threw Bolin against a wall. Dr. Matthews
    similarly asserted that based on “reports that Paul was
    knocked unconscious by his father’s blows on more than one
    occasion, it is quite likely that [Bolin’s] brain was damaged
    by his injuries.” Dr. Matthews further suggested that Bolin
    “may have experienced neuropsychological damage in utero
    before he was born.” A reasonable jurist could conclude that
    opinions such as these fail to draw a sufficient causal
    connection between Bolin’s childhood and his later claimed
    brain damage. See Bible v. Ryan, 
    571 F.3d 860
    , 871 (9th Cir.
    2009).
    The same is true of his alleged neurotoxin exposure.
    Dr. Khazanov opined that Bolin had been exposed to
    neurotoxins, such as lead paints, solvents, and fuels, which
    36                     BOLIN V. DAVIS
    “may result in organic brain damage.” Dr. Matthews
    similarly tried to connect Bolin’s alleged psychological
    impairments to neurotoxins, including based on his parents
    working in a Chicago factory where they “were exposed to
    noxious fumes and vapors.” But as was true with possible
    brain damage from childhood injuries, a reasonable jurist
    could conclude that the relationship between Bolin’s alleged
    mental deficiencies and his (or his family’s) neurotoxin
    exposure is insufficient—and that it is inconsistent with the
    lack of any other medical records bearing on this issue.
    Finally, a reasonable jurist could conclude that Bolin’s
    neurological deficits theory is of uncertain relevance to the
    offenses for which he was convicted. Drs. Khazanov and
    Matthews linked Bolin’s brain injuries to his confabulating.
    But it is unclear how Bolin’s confabulation explains his
    murdering Huffstuttler and Mincy. Similarly, a reasonable
    jurist (and jury) could well find the opinions of Bolin’s
    medical experts unpersuasive given Bolin’s deliberate
    shooting of three people and his strategic thinking after the
    murders, when Bolin recreated the scene as a failed drug deal
    and disabled Wilson’s vehicle to prevent his escape.
    Although Bolin’s experts have pointed to possible
    neurological deficiencies attributable to childhood trauma
    and environmental exposures, “reasonable jurists could
    debate the extent to which these factors significantly
    impaired his ability to appreciate the wrongfulness of his
    conduct or to conform his conduct to the law at the time of
    the murder.” Kayer, 141 S. Ct. at 525.
    Substance abuse at time of murders. Bolin maintains his
    counsel should have also argued to the jury that Bolin’s
    “ingestion of alcohol and cocaine before the crime, along
    with the many stressors in his life, exacerbated the effects of
    his deficits and made it even more likely that he would act
    BOLIN V. DAVIS                       37
    in response to perceived danger.” Once again, Bolin does
    not demonstrate prejudice under AEDPA.
    As an initial matter, it is not self-evident that under the
    circumstances of this case, the jury would necessarily regard
    Bolin’s alleged contemporaneous substance abuse as
    mitigating. See, e.g., Pinholster, 
    563 U.S. at 201
     (explaining
    that some mitigating evidence, such as “more serious
    substance abuse,” can be a “two-edged sword” because it
    might cause the jury to conclude the petitioner is “simply
    beyond rehabilitation” (quoting Atkins v. Virginia, 
    536 U.S. 304
    , 321 (2002))); Wackerly v. Workman, 
    580 F.3d 1171
    ,
    1178 & n.1 (10th Cir. 2009) (discussing case law
    “demonstrat[ing] that substance abuse evidence often can
    have more aggravating than mitigating effect”); Clisby v.
    Alabama, 
    26 F.3d 1054
    , 1056 (11th Cir. 1994) (“[M]any
    lawyers justifiably fear introducing evidence of alcohol and
    drug use.”).
    Nor is it apparent that a jury would regard an intoxication
    theory as mitigating alongside Cater’s dominant theory that
    Bolin was a loving and protective father who cared for
    others. As the Supreme Court has explained, the prejudicial
    impact of not presenting certain potentially mitigating
    evidence is lessened if that evidence would “undercut” a
    mitigation theory that counsel did present. Pinholster,
    
    563 U.S. at 202
    .
    Regardless, the evidence that Bolin was under the
    influence of drugs and alcohol when he killed Huffstuttler
    and Mincy is seemingly based only on Bolin’s own
    statements to Drs. Markman and Matthews, the latter some
    ten years after the fact. A reasonable jurist could thus
    conclude not only that Bolin’s theory of drug and alcohol
    inducement was not mitigating, but also that it was
    unsupported.
    38                    BOLIN V. DAVIS
    Childhood trauma. We turn next to Bolin’s claim that
    Cater failed to develop and present evidence about Bolin’s
    traumatic childhood. The evidence of Bolin’s childhood is
    set forth most comprehensively in Dr. Matthews’s expert
    declaration, which describes, among other things, how
    Bolin’s father William was prone to violent outbursts,
    including screaming, beating his wife and children, and on
    one occasion throwing Bolin down the stairs and knocking
    him unconscious.
    We note at the outset that Bolin’s arguments
    notwithstanding, Cater did investigate Bolin’s childhood by
    having Roger Ruby, his investigator, speak with Bolin’s
    sisters, Fran and Rosemary, and other members of Bolin’s
    extended family. As we discussed above, these interviews
    yielded information about Bolin’s difficult upbringing,
    including the physical abuse at the hands of his father. It is
    thus not clear that a further continuance would have made a
    material difference in the information Cater was able to
    obtain.
    We also note that though Bolin claims the jury was not
    told about his childhood, Bolin’s sister Fran did shed some
    light on it in her testimony. While it was not a dominant
    theme of Cater’s overall presentation, Fran told the jury
    about how their parents divorced when the children were
    young and how neither Bolin’s father nor his first stepfather
    wanted him in their homes. Fran recalled for jurors how
    Bolin was “thrown out” of the house and how he lived “on
    the streets.”
    It is true, of course, that Fran did not testify about her
    father’s physical abuse, which she had disclosed to Ruby
    during her meeting with him. We acknowledge that the
    accounts of Bolin’s difficult upbringing are disturbing. And
    we do not deny their potential value as a mitigation theory.
    BOLIN V. DAVIS                       39
    It is possible, of course, that Cater may have had a reasonable
    strategic judgment in avoiding this topic or not dwelling on
    Bolin’s childhood further—an issue we do not decide.
    Regardless, under AEDPA, we cannot conclude that the state
    court would be objectively unreasonable in determining that
    further development of this issue was unlikely to have
    changed the result.
    Based on Ruby’s investigation, Bolin’s sister Fran
    offered the most extensive account of Bolin’s father’s abuse.
    But Bolin’s parents divorced when Bolin was eight or nine
    years old, and Fran was four years younger than Bolin. The
    impact of her testimony would thus need to be considered
    alongside the fact that Fran was only four or five years old
    when she last lived with Bolin on a regular basis. And while
    Fran provided Ruby with information about Bolin’s father
    beating Bolin following their parents’ divorce, it is not
    apparent Fran and Bolin lived in the same home at this time.
    In evaluating the prejudice from Fran not testifying about
    Bolin’s childhood abuse, a reasonable jurist could thus
    consider that Fran’s base of knowledge may have been
    limited.
    And while Bolin’s other sister, Rosemary, corroborated
    some of Fran’s account, Rosemary lacked knowledge of the
    full timeframe, and Ruby otherwise questioned whether she
    would make a good witness. The prejudice to Bolin of
    Rosemary not testifying therefore must include the
    possibility that the jury may have viewed Rosemary
    unfavorably, as Ruby feared.
    Further affecting the potential mitigation value of
    Bolin’s abusive childhood is the fact that William’s violent
    conduct, while deplorable, was not so severe that it resulted
    in Bolin receiving medical attention. The extent of harm that
    Bolin experienced as a child makes this case analogous to
    40                    BOLIN V. DAVIS
    other cases involving either comparable or far more
    egregious childhood abuse where § 2254 relief was
    nonetheless denied. See, e.g., Pinholster, 
    563 U.S. at 201
    (denying relief even though petitioner came forward with
    additional evidence that he was “beaten with fists, belts, and
    even wooden boards”); Apelt v. Ryan, 
    878 F.3d 800
    , 815–16
    (9th Cir. 2017) (denying relief despite counsel’s failure to
    present evidence that “Apelt ‘came from a family
    background of gross poverty, alcoholism and violence which
    included emotional, physical and sexual abuse’”; that
    Apelt’s “abusive,” “alcoholic” father “beat his wife and
    children, including Apelt, with an iron rod”; and that Apelt
    was sexually assaulted as a child); Cain v. Chappell,
    
    870 F.3d 1003
    , 1021 (9th Cir. 2017) (denying relief even
    though petitioner endured “severe beatings and punishment”
    during his childhood, including an “untreated head injury”).
    William’s violent conduct toward Bolin, we also must
    note, does not rise nearly to the level of Bolin’s own
    depraved and lethal conduct. That as well makes Bolin’s
    difficult upbringing a more uncertain basis for mitigation.
    See, e.g., Wong v. Belmontes, 
    558 U.S. 15
    , 21, 27–28 (2009)
    (per curiam) (explaining that while petitioner endured a
    “‘terrible’ childhood” with an “extremely abusive” father,
    “[i]t is hard to imagine expert testimony and additional facts
    about [petitioner’s] difficult childhood outweighing the facts
    of [the] murder” for which he received a death sentence
    (emphasis omitted)); Benson v. Chappell, 
    958 F.3d 801
    , 833
    (9th Cir. 2020) (explaining that evidence of petitioner’s
    childhood sexual abuse “does not explain or justify [his]
    murder of Laura and her three children”); Samayoa v. Ayers,
    
    649 F.3d 919
    , 929 (9th Cir. 2011) (similar).
    Further, a reasonable jurist could also discount the
    prejudicial value of Bolin’s childhood experience based on
    BOLIN V. DAVIS                       41
    the amount of time that had elapsed between Bolin’s
    childhood and his much later murders of Huffstuttler and
    Mincy. Dr. Matthews, who provided the most extensive
    account of Bolin’s abuse, focuses largely on the period
    before Bolin’s parents divorced, when Bolin was eight or
    nine years old. And while Bolin allegedly continued to
    experience beatings after that (even though he was evidently
    spending less time with his father at this point), by the time
    Bolin was fourteen he had moved in with his mother and her
    new husband, James Amsbury (Bolin’s second stepfather).
    Thereafter, according to Dr. Matthews, Bolin’s “life changed
    dramatically” because Amsbury “took both Fran and [Bolin]
    in as though they were his own” and “did his best to be a
    father to [Bolin].” Meanwhile, Bolin would not murder
    Huffstuttler and Mincy until he was 42 years old.
    A reasonable jurist could conclude that the substantial
    gap in time between Bolin’s worst childhood experiences
    and his murders of Huffstuttler and Mincy is another feature
    of the record that weakens the mitigatory effect of William’s
    abusive conduct. See, e.g., Callahan v. Campbell, 
    427 F.3d 897
    , 937 (11th Cir. 2005) (holding that when evidence of
    physical abuse predated crimes by “several decades,” its
    mitigation value was “minimal”).
    Finally, if Cater had introduced evidence of Bolin’s own
    childhood abuse, it risked opening the door to rebuttal
    evidence of Bolin’s domestic abuse of his wife and children.

    558 U.S. at
    18–19, 24–26 (recognizing
    counsel’s “grave concerns” that, under “California
    evidentiary rules,” if his mitigation argument “swept too
    broadly,” evidence counsel had succeeded in having
    excluded “would come in for rebuttal”).
    The record indicates that Bolin had been arrested for
    battery of his second wife and for assault with a deadly
    42                    BOLIN V. DAVIS
    weapon and child cruelty toward one of his stepdaughters.
    When asked about the latter, he told his probation officer, “I
    whipped my stepdaughter’s ass with a belt.” Bolin had also
    been arrested for assault with a deadly weapon involving one
    of his stepdaughter’s teenage friends. As Bolin explained, a
    boy came at him, so he “kicked the shit out of him.” These
    incidents would have at least provided a counterpoint to
    Bolin’s own history of abuse as a child. And they would
    have likely dampened the mitigation impact of Cater’s
    central theory that Bolin was unworthy of the death penalty
    because of how he cared for his family. See Pinholster,
    
    563 U.S. at 202
    .
    In short, while Bolin’s violent upbringing may be the
    most compelling mitigation evidence that Cater did not
    present, a reasonable jurist could conclude that it is not so
    compelling, in combination with the other mitigating and
    aggravating factors, to indicate that it could have changed
    the result in Bolin’s case.
    Military service. Bolin also argues that Cater should
    have developed and presented more evidence about Bolin’s
    military service. But contrary to the suggestion that the jury
    was unaware of this aspect of Bolin’s life, Cater during the
    penalty phase peppered his witness questioning with
    references to Bolin’s service in the Navy and Vietnam. The
    jury heard from Mary and Frances that Bolin had served in
    the Navy in Vietnam when Mary was a young child. And
    Cater repeatedly reminded the jury in his closing argument
    about Bolin’s military service in Vietnam and how Bolin had
    “served his country.”
    Although Cater could have presented more detail about
    the specifics of Bolin’s experience in the Navy, it is not
    apparent that this additional information creates a materially
    different portrait in mitigation. Although Bolin now
    BOLIN V. DAVIS                       43
    suggests that his service in Vietnam caused him to develop
    unidentified mental health problems, including through
    possible neurotoxin exposure, Bolin’s time in Vietnam was
    short (approximately 6 months).
    Bolin does point to some positive reviews from military
    superiors, his stay in a military hospital for an “anxiety
    reaction” (prior to going to Vietnam), and the back injury he
    sustained on a ship after returning from Vietnam. But this
    further background information does not change our
    conclusion. We can agree that, like Bolin’s military service
    generally, these additional details may have additional value
    in mitigation. Nonetheless, a reasonable jurist could
    conclude that Bolin identifies nothing in his military service
    that presents a supported and compelling basis from which
    the jury would have reached a different conclusion in the
    penalty phase.
    That is especially so considering that the more favorable
    or sympathetic aspects of Bolin’s time in the Navy must be
    considered alongside other more negative aspects, which the
    State might have used in rebuttal had Cater dwelled on the
    issue more. See Belmontes, 
    558 U.S. at 26
     (courts must
    consider evidence “that would have been presented had [the
    petitioner] submitted the additional mitigation evidence”).
    Among other things, Dr. Matthew’s report discusses how
    Bolin’s stepfather pushed Bolin to join the service, hoping
    the Navy would straighten Bolin out after he was arrested
    and put on probation for burglary. Once in the Navy, Bolin
    had further disciplinary problems, including a court martial,
    for offenses that included intoxication on duty from
    “chemicals” and alcohol, unauthorized absence, and use of
    an “unissued identification card.” Bolin also had told a Navy
    psychiatrist that he wanted to “beat up someone” and
    reportedly showed hostility to others. That Bolin’s military
    44                     BOLIN V. DAVIS
    career does not tell a consistently positive story—or even a
    consistent one—means that a reasonable jurist could
    determine that more information on Bolin’s military service
    would not have likely changed the jury’s decision.
    Good character. Bolin argues that Cater should have
    developed and presented additional evidence of his good
    character, based on Bolin’s role as a protective parent and
    his positive prison adjustment. We need not dwell on this
    point for long. As we described above, the jury heard
    considerable testimony about Bolin’s role as a protective
    parent to his daughters and stepdaughters. Indeed, this was
    the primary theme of Cater’s presentation to the jury.
    Additional evidence on this point would have been
    cumulative, and thus unlikely to affect the result. See, e.g.,
    Pinholster, 
    563 U.S. at 200
     (rejecting Strickland claim under
    AEDPA when “[t]he ‘new’ evidence largely duplicated the
    mitigation evidence at trial”).
    A similar point answers Bolin’s argument that Cater
    should have said more about Bolin’s ability to adjust to
    prison life. Cater had already called as a witness Nancy
    Belden, a correctional officer, and she told the jury that Bolin
    was cooperative and did not cause problems in custody,
    agreeing that he was a “model inmate” while he was
    incarcerated in 1985. Cater used that testimony in his
    closing to argue that Bolin functioned well in a structured
    environment, lumping in his time in the Navy. Once again,
    Bolin has not demonstrated that additional information on
    his behavior in prison would have altered the result in his
    case. See, e.g., 
    id.
    Expert testimony. Finally, we consider Bolin’s argument
    that Cater should have put on expert testimony to support
    Bolin’s penalty phase defense. Contrary to Bolin’s premise,
    Cater was not without expert opinion: he had Dr. Markman’s
    BOLIN V. DAVIS                         45
    evaluation, which was largely unfavorable. But once again,
    even assuming Cater was deficient in not consulting further
    experts and bringing forward expert testimony to synthesize
    Bolin’s life history, we cannot conclude Bolin has shown
    prejudice under AEDPA on the facts of this case.
    Bolin cites no authority suggesting that a defense
    lawyer’s determination not to use an expert witness during
    the penalty phase constitutes per se prejudice under
    Strickland. And we are aware of no such authority either,
    especially in the AEDPA context. Such a rule would be
    contrary to counsel’s well-established discretion, within the
    bounds of reasonable professional judgment, as to whether
    to use experts. See Richter, 
    562 U.S. at
    106–07 (“Rare are
    the situations in which the ‘wide latitude counsel must have
    in making tactical decisions’ will be limited to any one
    technique or approach. . . . Here it would be well within the
    bounds of a reasonable judicial determination for the state
    court to conclude that defense counsel could follow a
    strategy that did not require the use of experts . . . .” (quoting
    Strickland, 
    466 U.S. at 689
    )); Bonin v. Calderon, 
    59 F.3d 815
    , 834 (9th Cir. 1995) (“[T]he presentation of expert
    testimony is not necessarily an essential ingredient of a
    reasonably competent defense.”).
    Instead, we must evaluate Bolin’s charge that Cater
    should have used an expert based on the expert testimony
    Bolin now proffers and the overall record in this case. For
    the reasons we have discussed above, the expert testimony
    that Bolin advanced to the state habeas court—from
    Drs. Khazanov and Matthews—has limited mitigation
    value.
    Further weakening Bolin’s focus on the lack of expert
    testimony is that if Bolin had offered such testimony, the
    State could have offered its own expert in rebuttal. See
    46                    BOLIN V. DAVIS
    Pinholster, 
    563 U.S. at 201
     (psychiatric evidence could have
    “opened the door to rebuttal by a state expert”); Belmontes,
    
    558 U.S. at 25
     (explaining that the “‘more-evidence-is-
    better’ approach” “might seem appealing” but carried
    significant risks of rebuttal evidence in response to
    “heavyhanded” attempts to “portray [the defendant] in a
    positive light, with or without experts”).
    We need look no further than Dr. Markman, the expert
    Bolin’s own counsel had retained prior to trial.
    Dr. Markman evaluated Bolin in 1990, not long after the
    murders. And his conclusions were not helpful to Bolin’s
    current theory of mental impairment. In particular, and
    among other things, Dr. Markman opined that Bolin was
    “fully oriented in all spheres,” of “above normal intelligence
    with an excellent fund of knowledge,” with “no evidence of
    a major mental disorder, thought disorder[,] or psychosis.”
    Dr. Markman also cited Bolin’s “repeated history of
    aggressive behavior” while noting that if Bolin had
    “fabricated” information he provided to Markman, Bolin
    was “fully aware that he is doing so.”
    While Bolin now maintains that Dr. Markman’s
    evaluation was not translatable for penalty phase purposes
    and that Markman based his opinions on insufficient
    information, those arguments misunderstand the relevance
    of Dr. Markman’s report for purposes of our present
    analysis. Dr. Markman’s opinions could themselves have
    had some shortcomings. But they reflect the type of expert
    opinions that the State could have put on, had Cater put on
    an expert like Drs. Matthews or Khazanov.             That
    Dr. Markman had evaluated Bolin more contemporaneously
    with the murders, and was an expert that Bolin’s own
    counsel had retained, only further underscore the State’s
    ability to offer its own expert in rebuttal. It would be
    BOLIN V. DAVIS                       47
    objectively reasonable for the state habeas court to conclude
    that under the facts of this case, Bolin was not prejudiced by
    the lack of expert testimony because the prosecution could
    have presented an opinion similar to Dr. Markman’s, which
    was unhelpful to Bolin.
    2
    Viewed as a collective whole, the additional mitigating
    evidence Bolin has brought forward in habeas is not
    inevitably compelling under AEDPA. This on its own would
    be sufficient to deny relief under § 2254. Pinholster,
    
    563 U.S. at 202
    . But that conclusion is bolstered when the
    new mitigating evidence is considered alongside the
    aggravating circumstances that the State presented.
    As the Supreme Court has explained, even before the
    AEDPA overlay, “to establish prejudice” Bolin “must show
    a reasonable probability that the jury would have rejected a
    capital sentence after it weighed the entire body of
    mitigating evidence . . . against the entire body of
    aggravating evidence.” Belmontes, 
    558 U.S. at 20
    ; see also
    Mickey v. Ayers, 
    606 F.3d 1223
    , 1245 (9th Cir. 2010)
    (explaining that the Supreme Court has “reaffirmed that the
    facts of the crime play an important role in the prejudice
    inquiry”). And under AEDPA, Bolin must show even more:
    that the state habeas court’s reweighing of the aggravating
    and mitigating circumstances was not merely unpersuasive,
    but “objectively unreasonable.” Andrade, 538 U.S. at 75.
    Bolin cannot make this showing.
    The crimes that lead to capital convictions often present
    highly aggravated circumstances. This case is no exception.
    But if anything, it involves uniquely cruel and unjustified
    conduct that reflected an appreciable indifference to human
    life. In an apparent effort to maintain the secrecy of his
    48                     BOLIN V. DAVIS
    marijuana grow operation, Bolin shot two men four times
    each. Mincy implored Bolin to spare him, but Bolin killed
    him anyway. Bolin took the effort to get a second weapon
    to use on Huffstuttler’s motionless body after he had already
    shot him once. And Bolin then elaborately dressed the scene
    with broken glass, marijuana, and chili, placing a gun in
    Huffstuttler’s dead hand. Bolin also shot Wilson in the
    shoulder, hunted for him in the forest, and, when he failed to
    find him, immobilized Wilson’s vehicle and left Wilson to
    perish in an unforgiving mountainous terrain. And this is to
    say nothing of the other past incidents of violent conduct that
    the State presented involving Kenneth Ross and Matthew
    Spencer—conduct that resulted in serious injury and, in the
    case of Ross, could have resulted in death.
    Taken as a whole, “[t]he State presented extensive
    aggravating evidence.” Pinholster, 
    563 U.S. at 198
    . A
    reasonable jurist could easily conclude that the additional
    mitigating evidence Bolin now proffers was unlikely to have
    led the jury to choose a different sentence. We thus hold that
    even if Cater acted deficiently in failing to develop and
    present more mitigating evidence and in failing to seek
    additional time for that endeavor, under AEDPA Bolin
    cannot show he was prejudiced.
    V
    Lastly, we address Bolin’s request for new counsel. On
    two earlier occasions, Bolin filed pro se requests for
    alternative counsel, and both times we ordered his appointed
    counsel to respond. Both times, we concluded that his
    counsel’s response was satisfactory under Martel v. Clair,
    
    565 U.S. 648
     (2012). Thus, we denied Bolin’s requests.
    Since then, Bolin has filed several additional pro se
    motions requesting alternative counsel and related relief.
    BOLIN V. DAVIS                     49
    We have carefully reviewed those filings as well. We deny
    Bolin’s latest requests. Although Bolin has not prevailed in
    this appeal, his appointed counsel ably discharged their
    duties in representing him before this Court.
