    CADY, Justice.
    In this case we must determine if the defendant’s constitutional
    rights to conflict-free counsel were violated.       In addition, we must
    determine whether there was sufficient evidence to convict the defendant
    of first-degree murder.   Finding no constitutional violation or problem
    pertaining to the sufficiency of the evidence, we affirm the defendant’s
    conviction.
    I. Background Facts and Proceedings.
    In 1990 law enforcement officers found Richard Tasler’s skeletal
    remains buried on Joel Smitherman’s property. As a result, and after a
    long investigation, the State finally charged Smitherman with Tasler’s
    murder on May 13, 2004. The court appointed the Marshalltown Public
    Defender’s Office (MPDO) to represent Smitherman on May 13, 2004. On
    May 17 MPDO attorneys Melissa Anderson and Ray Reel filed their
    appearances on behalf of Smitherman.
    On May 18, 2004, a prison inmate—Jason Williamson—came
    forward with information related to the prosecution of Smitherman.
    Williamson was in jail on felony and serious misdemeanor charges. Reel
    represented Williamson on his serious misdemeanor charges, and a
    private   attorney   represented   Williamson   on    his   felony   charges.
    Williamson was interviewed by law enforcement officials on May 19,
    2004. The next day the State informed the MPDO that Williamson would
    likely be added to the trial information as a witness for the prosecution.
    On May 21, 2004, Anderson and Reel discussed the addition of
    Williamson as a witness. Anderson told Reel she did not want to know
    anything about the potential witness or the pending cases against him.
    Anderson even indicated she was not sure of Williamson’s name. As a
    3
    result of their conversation, Reel immediately made the decision to
    withdraw from representing Williamson and was relieved of that duty by
    May 25. 1
    Reel additionally withdrew from representing Smitherman on May
    27. 2   At this time, Reel was replaced by Shannon Leighty, who also
    worked for the MPDO. Thereafter, Leighty represented Smitherman as
    “second chair” to Anderson. 3           At all times in the present proceeding
    Anderson remained as primary counsel to Smitherman.                         The MPDO
    represented Smitherman continually from the day he was charged—May
    13, 2004—until the day he was sentenced—April 8, 2005. Specifically,
    Reel represented Smitherman from May 17 to May 27, and Reel
    represented Williamson until May 25.                   Thus, Reel simultaneously
    represented Williamson and Smitherman from May 17 to May 25,
    although he was not informed that Williamson would be a potential
    witness against Smitherman until May 20, and by May 21 he had made
    the decision to withdraw from Reel’s case.                   The MPDO, of course,
    simultaneously represented Smitherman and Williamson from May 13
    1The record does not exactly disclose when Reel withdrew from representing
    Williamson, although a search performed on Iowa Courts Online indicates the court
    relieved the MPDO of further responsibility in Williamson’s case on May 25. Anderson
    testified that “[u]pon hearing that [Williamson would be a potential witness], I informed
    Ray [Reel] that he needed to withdraw immediately from that case. I don’t know for
    certainty if that was filed on the 21st of May or if it was the early part of the following
    week.” Anderson also testified that “[Reel] withdrew from Williamson within 24 hours
    [of hearing that Williamson might be a potential witness].” Thus, it appears from these
    statements that Reel made the decision to withdraw on May 21, but did not file his
    withdrawal or receive permission to withdraw until May 25.
    2The “Amended and Substituted Appearance” was mailed on May 25, 2004, but
    was not filed with the Hardin County district court clerk until May 27, 2004.
    3Leighty was eventually replaced by Rebecca Hanson, also an attorney for the
    MPDO. This replacement took place on February 11, 2005, and was the result of
    Leighty transferring offices.
    4
    (when the court appointed the MPDO to represent Smitherman) until
    May 25 (when the court in Williamson’s matter relieved the MPDO of
    further responsibility in Williamson’s case).
    Because of our decision in State v. Watson, 
    620 N.W.2d 233
    (Iowa
    2000), and the circumstances facing the parties, the State made an
    application for a “Watson hearing” on June 11, 2004. In its application
    the State set forth the facts above, acknowledged that Reel had been
    replaced by Leighty, and stated “[t]he State has also been assured that
    Ray Reel will be separated from the current case so that no actual
    conflict arises.” The district court held a hearing on the matter on June
    28, 2004. At the hearing the state prosecutor, Scott Brown, testified for
    the State and said:
    Judge, we filed this application for [a] Watson hearing
    to raise this issue. I don’t want the court to read into that
    we’re wishing the Public Defender’s Office in Marshalltown to
    have to be removed from this case. That’s not our intention
    in filing it. We think we are required to do it whenever there
    is a potential conflict of interest so all this is laid out on the
    record and Mr. Smitherman is aware of the relationship
    between his attorney and a potential prosecution witness.
    Likewise, the attorneys for the MPDO argued its representation did not
    violate our holding in Watson, and that a “Chinese Wall,” or an office
    procedure to insulate Reel from the case, had been put into place.
    At the hearing, the court specifically addressed Smitherman as
    follows:
    THE COURT:       Mr. Smitherman, have you had a
    chance to discuss these issues with your attorney Ms.
    Anderson?
    THE DEFENDANT: Yes, I have.
    THE COURT: Do you have any concerns about Ms.
    Anderson continuing in your defense in this case?
    THE DEFENDANT: No. I’m just disappointed in the
    loss of Mr. Reel. . . .
    5
    THE COURT:      So you understand, however, that
    because of Mr. Reel’s representation of [Williamson], he is
    prohibited from proceeding in this case?
    THE DEFENDANT: Yes, sir.
    THE COURT: And even though there was a short
    period of time, about maybe a week or so, where Mr. Reel
    represented both you and [Williamson], you’re comfortable
    with the Marshalltown Public Defender’s Office proceeding in
    this case?
    THE DEFENDANT: Yes, I am.
    As a result of the hearing the district court entered an order on June 30,
    2004 concluding “there is no actual or potential conflict of interest,” and
    “that the representation of the defendant by Ms. Anderson and Ms.
    Leighty is not precluded by the court’s holding in Watson.”      The case
    proceeded to trial and the jury found Smitherman guilty of first-degree
    murder. On April 8, 2005 Smitherman was sentenced to life in prison
    without parole.
    II. Issues and Standard of Review.
    On appeal, Smitherman makes two arguments: (1) his state and
    federal constitutional rights were violated because of an impermissible
    conflict of interest that was created by the MPDO’s simultaneous
    representation of the prosecution’s witness and himself, and (2) there
    was insufficient evidence to convict him of first-degree murder.       Our
    review is de novo when the defendant alleges a conflict of interest
    implicating the right to counsel. See State v. Powell, 
    684 N.W.2d 235
    ,
    238 (Iowa 2004); Pippins v. State, 
    661 N.W.2d 544
    , 548 (Iowa 2003). Our
    review is for errors at law when the defendant challenges his or her
    conviction based on the sufficiency of the evidence. See State v. Speicher,
    
    625 N.W.2d 738
    , 740 (Iowa 2001).        “[A] jury verdict is binding on us
    when supported by substantial evidence,” and “evidence is substantial if
    it could convince a rational jury of a defendant’s guilt beyond a
    6
    reasonable doubt.” 
    Id. at 740–41
    (citing State v. Hopkins, 
    576 N.W.2d 374
    , 377 (Iowa 1998); State v. Casady, 
    597 N.W.2d 801
    , 804 (Iowa
    1999)). We must view the record in the light most favorable to the State,
    and consider the evidence supporting not just guilt, but innocence, too.
    
    Id. at 741
    (citing 
    Hopkins, 576 N.W.2d at 377
    ).
    III. Conflict of Interest.
    Conflict-of-interest claims are typically raised in ineffective-
    assistance-of-counsel claims. See, e.g., Mickens v. Taylor, 
    535 U.S. 162
    ,
    164, 
    122 S. Ct. 1237
    , 1239–40, 
    152 L. Ed. 2d 291
    , 299 (2002)
    (“[Petitioner] alleg[ed], inter alia, that he was denied effective assistance of
    counsel because one of his court-appointed attorneys had a conflict of
    interest at trial.”). Smitherman, however, has not specifically alleged an
    ineffective-assistance-of-counsel claim.           Nevertheless, he has alleged a
    violation of his federal Sixth Amendment rights, and his corresponding
    rights under article I, section 10 of Iowa’s Constitution due to an
    impermissible conflict of interest. 4 When a defendant alleges a violation
    of these constitutional rights due to an impermissible conflict of interest,
    our basic analysis does not change depending on how the defendant has
    framed the violation—i.e., as a claim of ineffective assistance of counsel
    or otherwise.      The analysis we use in this case is largely the same
    analysis we would use if the defendant had specifically alleged a claim of
    ineffective assistance of counsel due to an impermissible conflict of
    interest.    See 
    Watson, 620 N.W.2d at 235
    –37 (analyzing a conflict-of-
    4These    constitutional provisions safeguard the defendant’s right to a fair trial,
    which expressly includes the guarantee to “assistance of counsel.” Iowa Const. art. I,
    § 10; see U.S. Const. amend. VI (using the identical words “Assistance of Counsel”).
    The assistance of counsel, of course, implies the effective assistance of counsel. See
    
    Mickens, 535 U.S. at 166
    , 122 S. Ct. at 
    1240, 152 L. Ed. 2d at 300
    (“[A]ssistance which
    is ineffective in preserving fairness does not meet the constitutional mandate . . . .”).
    7
    interest claim under precedent based on claims of ineffective assistance
    of counsel due to a conflict of interest); State v. Williams, 
    652 N.W.2d 844
    , 847 (Iowa Ct. App. 2002) (“The foundation for this type of claim
    [(allegations of a conflict of interest)] is an alleged denial of an accused’s
    constitutional right to effective assistance of counsel.”). The analysis is
    basically one question:       whether the defendant has made a showing
    whereby we can presume prejudice.            See 
    Watson, 620 N.W.2d at 238
    (stating the “legal principles applicable to conflict-of-interest claims” and
    recognizing situations where prejudice is presumed, such as “on remand,
    [when] an actual conflict is found, prejudice is presumed and reversal is
    mandated”).      If so, the defendant’s constitutional rights have been
    violated and he or she is entitled to a new trial.
    Notably, this analysis (whether as a specific claim of ineffective
    assistance of counsel due to a conflict of interest, or whether as a generic
    conflict-of-interest claim) is different than the typical two-part analysis
    for claims of ineffective assistance of counsel under Strickland v.
    Washington, 
    466 U.S. 668
    , 687, 
    104 S. Ct. 2052
    , 2064, 
    80 L. Ed. 2d 674
    ,
    693 (1984). 5         The difference can be summarized quite easily:               A
    defendant has less to prove in conflict-of-interest cases. Whereas in a
    typical claim of ineffective assistance of counsel the defendant must
    prove prejudice by showing the result of the proceeding would have been
    different, a conflict of interest claim only requires the defendant to make
    a showing whereby we can presume prejudice. See, e.g., 
    Mickens, 535 U.S. at 174
    , 122 S. Ct. at 
    1245, 152 L. Ed. 2d at 306
    (noting Strickland
    requires “in other ineffectiveness-of-counsel cases . . . a showing of
    5The typical two-part test under Strickland asks (1) whether counsel performed
    an essential duty, and if not, (2) whether prejudice resulted. See State v. Lane, 
    726 N.W.2d 371
    , 393 (Iowa 2007).
    8
    probable effect upon the outcome of trial,” but that in conflict of interest
    cases such prejudice is presumed when there’s a showing of defense
    counsel’s “defective performance”). 6 Thus, in this case we are looking to
    see whether Smitherman has made a showing whereby we can presume
    prejudice.
    In Watson, we held that under the Sixth Amendment we could
    presume prejudice when there was an actual conflict the trial court
    should have known about, and yet failed to inquire 
    into. 620 N.W.2d at 237
    –39.      In so holding, we examined United States Supreme Court
    precedent, and cases interpreting that precedent, to reject a requirement
    that the defendant must show his counsel’s performance was adversely
    affected by the conflict of interest. 
    Id. at 236–38.
    We said,
    Our review of the cases leads us to agree with those
    courts holding that where the trial court knew or should
    have known of a particular conflict, reversal is required
    6Perhaps   this was best explained in the following:
    [I]t also follows that defects in assistance that have no probable
    effect upon the trial’s outcome do not establish a constitutional violation.
    As a general matter, a defendant alleging a Sixth Amendment violation
    must demonstrate a “reasonable probability that, but for counsel’s
    unprofessional errors, the result of the proceeding would have been
    different.”
    There is an exception to the general rule. We have spared the
    defendant the need of showing probable effect upon the outcome, and
    have simply presumed such effect, where assistance of counsel has been
    denied entirely or during a critical stage of the proceedings. When that
    has occurred, the likelihood that the verdict is unreliable is so high that
    a case-by-case inquiry is unnecessary. But only in “circumstances of
    that magnitude” do we forgo individual inquiry into whether counsel’s
    inadequate performance undermined the reliability of the verdict.
    We have held in several cases that “circumstances of that
    magnitude” may also arise when the defendant’s attorney actively
    represented conflicting interests.
    
    Mickens, 535 U.S. at 166
    , 122 S. Ct. at 
    1240–41, 152 L. Ed. 2d at 300
    –01 (internal
    citations omitted).
    9
    without a showing that the conflict adversely affected
    counsel’s performance, even though no objection was made
    at trial.
    
    Id. at 238.
    Instead, all that was required was an actual conflict, which
    we defined as “ ‘a situation conducive to divided loyalties.’ ” 
    Id. at 239
    (quoting Smith v. Lockhart, 
    923 F.2d 1314
    , 1320 (8th Cir. 1991)).
    Less than two years later, however, the United States Supreme
    Court reached a contrary conclusion.     In Mickens, the Supreme Court
    reviewed its precedent and concluded
    the [Cuyler v.] Sullivan[, 
    446 U.S. 335
    , 
    100 S. Ct. 1708
    , 
    64 L. Ed. 2d 333
    (1980),] standard is not properly read as
    requiring inquiry into actual conflict as something separate
    and apart from adverse effect. An “actual conflict,” for Sixth
    Amendment purposes, is a conflict of interest that adversely
    affects counsel’s 
    performance. 535 U.S. at 172
    n.5, 122 S. Ct. at 1244 
    n.5, 152 L. Ed. 2d at 305 
    n.5.
    Thus, when the trial court failed to conduct an inquiry (or even if it did
    conduct an inquiry), the Supreme Court required the defendant to show
    his counsel’s performance was adversely affected by the conflict of
    interest before it would presume prejudice and find a Sixth Amendment
    violation warranting reversal. 
    Id. at 172–73,
    122 S. Ct. at 
    1244–45, 152 L. Ed. 2d at 304
    –05.
    We recognize our holding in Watson under the Sixth Amendment is
    impacted by the Supreme Court’s decision in Mickens.           Of course,
    Watson may still be valid under our state constitution.      See State v.
    Cline, 
    617 N.W.2d 277
    , 285 (Iowa 2000) (recognizing we can provide
    greater protections under our state constitution), disavowed on other
    grounds by State v. Turner, 
    630 N.W.2d 601
    , 606 n.2 (Iowa 2001). But
    we need not decide that question now because a different question is
    before us:   namely, under what circumstances are we to presume
    10
    prejudice when the trial court has performed an inquiry?            We are
    convinced those circumstances must include the defendant’s ability to
    show what was required in Mickens—adverse effect upon defense
    counsel’s performance.     While we were willing to presume prejudice
    without requiring adverse effect in Watson, we believe the facts of Watson
    are sufficiently distinguishable from this case so the reasons behind our
    holding in Watson, even if still viable after Mickens under our state
    constitution, are not applicable here. Under the circumstances in this
    case, we hold Smitherman must show adverse effect in order to prevail
    under either the Sixth Amendment or article I, section 10 of the Iowa
    Constitution.
    The differences between this case and Watson are immediately
    apparent. Most notably, the trial court in this case conducted an inquiry
    into the conflict in order to protect the defendant’s rights. This inquiry,
    together with Smitherman’s lack of objection, casts a different light on
    the need for the automatic reversal rule we recognized in Watson. When
    conflicted defense counsel represents a defendant during the course of
    the trial because the court did not conduct an inquiry into the conflict,
    our confidence in the result of the verdict is undermined. 
    Mickens, 535 U.S. at 168

    representation is inherently suspect because it can effectively seal the
    lips of the attorney on critical matters and tend to prevent the attorney,
    often in very subtle ways, from providing effective representation.      
    Id. (citing Holloway
    v. Arkansas, 
    435 U.S. 475
    , 489–90, 
    98 S. Ct. 1173
    ,
    1181, 
    55 L. Ed. 2d 426
    , 438 (1978)). The nature of the conflict makes it
    difficult to effectively measure the harm visited on the trial by conflicted
    counsel. 
    Id. On the
    other hand, when the court makes an inquiry in
    11
    some form into the conflict, the attorney is no longer quietly inflicting the
    inherent harm into the trial that supports the automatic reversal rule.
    Instead, a prophylactic inquiry by the court ameliorates the suspicion of
    harm and lessens the need for a rigid rule of automatic reversal. See
    
    Holloway, 435 U.S. at 489
    , 98 S. Ct. at 
    1181, 55 L. Ed. 2d at 437
    (noting
    the rigidity of such a rule because a conviction could be reversed even if
    no actual prejudice is shown and the defendant is clearly guilty).
    Additionally, the lack of objection by the defendant, or explicit
    acquiescence in his representation, 7 makes it more palatable to impose
    an   obligation     to   show     an    adverse     effect   on    defense     counsel’s
    performance.
    In this case, all parties and the court were manifestly aware of the
    conflict, and took several precautions to assure the defendant’s rights
    were not violated.       These precautions included setting up a “Chinese
    wall” between Reel and the rest of the MPDO, and ending the MPDO’s
    representation of Williamson and Reel’s representation of Smitherman.
    In addition, all parties, including the defendant himself, believed the
    situation did not present an impermissible conflict of interest. Finally,
    while Reel and the MPDO represented both Smitherman and Williamson
    at the same time, such simultaneous representation was very brief.
    7The    State additionally argued Smitherman waived his right to conflict-free
    counsel. See 
    Holloway, 435 U.S. at 483
    n.5, 98 S. Ct. at 1178 
    n.5, 55 L. Ed. 2d at 433
    
    n.5 (“A defendant may waive his right to the assistance of an attorney unhindered by a
    conflict of interest.”). This issue is moot in light of our holding. Therefore, we express
    no opinion as to whether Smitherman’s acquiescence in his representation amounted to
    a valid waiver of his right to conflict-free counsel, see United States v. Brekke, 
    152 F.3d 1042
    , 1045 (8th Cir. 1998) (noting such a waiver “must be knowing, voluntary, and
    intelligent”), or whether such a waiver is adjudged by the same exacting standards we
    have required in order to waive the right to counsel, see Hannan v. State, ___ N.W.2d
    ___, ___ (Iowa 2007).
    12
    Moreover, even if Reel was required to withdraw and such
    withdrawal was imputed to the MPDO, 8 the imputed disqualification rule
    Smitherman cites does not itself establish a constitutional violation. See
    Nix v. Whiteside, 
    475 U.S. 157
    , 165, 
    106 S. Ct. 988
    , 993, 
    89 L. Ed. 2d 123
    , 134 (1986) (“[B]reach of an ethical standard does not necessarily
    make out a denial of the Sixth Amendment guarantee of assistance of
    counsel.”); Iowa Code of Prof’l Responsibility, DR 5-105(E) (imputing the
    disqualification of one lawyer to the lawyer’s firm); see also Lambert v.
    Blodgett, 
    393 F.3d 943
    , 986 (9th Cir. 2004) (“[T]he Supreme Court has
    never applied the ethical imputed disqualification rule in Sixth
    Amendment analysis.”).            In addition, we are not persuaded by
    Smitherman’s argument that the MPDO’s investigator labored under an
    impermissible conflict of interest. The Sixth Amendment guarantees the
    right to conflict-free counsel, and Smitherman has not shown how the
    MPDO investigator was involved in Williamson’s and Smitherman’s
    cases, or how such involvement would establish a violation of the
    constitutional right to conflict-free counsel.
    Of course, the most important point is that Smitherman has not
    shown his counsel was adversely affected by the conflict of interest.
    There is nothing in the record to suggest defense counsel’s performance
    8We   express no opinion as to whether the MPDO was required to withdraw
    under our old or new ethical rules, although we note several authorities recognize that
    different rules should govern the imputation of conflicts among government lawyers.
    See United States v. Reynoso, 
    6 F. Supp. 2d 269

    was affected by a conflict of interest. Smitherman argues otherwise, and
    says he would have accepted a plea agreement to a lesser charge had his
    counsel acted differently. He also argues a more zealous defense would
    have   found    additional   exculpatory    evidence   and   exploited   the
    weaknesses in the State’s case. This, however, is not a showing that his
    counsel was adversely affected by a conflict of interest. There is simply
    no connection between the alleged conflict and the alleged deficiencies in
    Smitherman’s defense. See, e.g., United States v. Stitt, 
    441 F.3d 297
    , 303
    (4th Cir. 2006) (recognizing a three-part test to determine whether
    adverse effect has been shown, which includes a determination that the
    alleged deficiency is causally connected to the conflict).
    Smitherman’s basic argument is that there was a conflict under
    Watson that requires us to reverse his conviction. As we have already
    stated, we are not willing to follow Watson in these circumstances, even
    under article I, section 10 of the Iowa Constitution. Because we require
    adverse effect to be shown under these circumstances, it would not
    matter if we found Smitherman’s counsel labored under an “actual
    conflict” as we defined that term in Watson (a situation conducive to
    divided loyalties), because his defense counsel did not labor under an
    “actual conflict” as the United States Supreme Court has defined the
    term (one requiring adverse effect).          As a result, Smitherman’s
    constitutional rights to conflict-free counsel were not violated.
    IV. Sufficiency of the Evidence.
    Smitherman claims there is insufficient evidence to support the
    verdict. See State v. Legear, 
    346 N.W.2d 21
    , 23 (Iowa 1984) (recognizing
    substantial evidence must exist to uphold the verdict). The State initially
    argues Smitherman cannot raise this argument because he failed to
    14
    preserve error. We will assume Smitherman preserved error to reach the
    merits of his argument.
    In this case, Smitherman primarily attacks the State’s theory of the
    case. The State theorized that Smitherman was paid to shoot Tasler in
    1986 because Tasler had become a liability to an individual named Tim
    Houser, who was Tasler’s partner in a cocaine dealing business. There
    was evidence to suggest Smitherman lured Tasler to go with him on a
    trip, that he shot Tasler five times in the back of the head, and that he
    then   buried   Tasler’s   body   on    his   property   near    Union,   Iowa.
    Furthermore,    evidence    revealed    Smitherman       lied   about   Tasler’s
    whereabouts following the murder, and told others he had shot
    “someone.” Smitherman also attempted to bribe a cell mate to lie for him
    about the matter.
    Smitherman largely points to evidence at trial that Houser, not
    Smitherman, had the motive to kill Tasler.        Furthermore, Smitherman
    points to evidence that suggested Tasler planned his own disappearance,
    and had plans to disguise his physical appearance through plastic
    surgery.   Moreover, some witnesses testified Tasler was seen after the
    date the State claimed he was killed by Smitherman.
    The jury had two distinct theories presented at trial. They were
    required to sift through the conflicting evidence and assess the credibility
    of the witnesses.   In the end, it is clear the verdict revealed the jury
    rejected Smitherman’s theory and evidence, and found the State’s
    evidence to be more compelling. Upon our review of all the evidence, we
    conclude substantial evidence supports the verdict.

    V. Conclusion.
    We need not determine the validity of the defendant’s alleged
    waiver because we find the defendant has failed to show his counsel’s
    performance was adversely affected by the alleged conflict of interest in
    this case. As a result, he has not established a violation under the Sixth
    Amendment or the Iowa Constitution and is not entitled to a new trial.
    Finally, there was sufficient evidence to convict him of first-degree
    murder.
    AFFIRMED.
    All justices concur except Appel, J., who takes no part.
