    not debate the correctness of the district court’s disposition of Issues One and
    Two, we DENY Roberson’s application for a certificate of appealability as to
    * Pursuant to 5TH CIR. R. 47.5, the court has determined that this opinion should not

    of the district court’s disposition of Issue Three, and we GRANT Roberson’s
    application as to that issue.
    I.
    On January 31, 2002, Nikki Curtis was brought into the emergency room
    in Palestine, Texas. She was not breathing and had a blue color to her skin.
    Despite the efforts of the medical providers in Palestine and, later, in Dallas,
    Nikki succumbed to her injuries and passed away later that day. She was two
    years old.
    Nikki was the daughter of the Petitioner-Appellant, Robert Roberson.
    After a custody battle, Nikki had come to live with Roberson and his girlfriend,
    Teddie Cox. Cox’s daughter, Rachel, also lived with them. The week of Nikki’s
    death, Cox was admitted to the hospital for a hysterectomy and had to stay
    overnight. Nikki’s maternal grandparents, the Bowmans, babysat Nikki while
    Cox was in the hospital, as Cox did not want to leave Nikki alone with
    Roberson. On January 30, however, Mrs. Bowman became ill, and she asked
    to have Roberson come pick up Nikki. Cox testified that Roberson was mad
    that he had to go get Nikki, but eventually did so.
    The next morning, Cox called Roberson to tell him that she had been
    discharged from the hospital and to ask him to pick her up. Roberson told Cox
    over the phone that he thought he needed to come to the hospital anyway, as
    Nikki was not breathing. Cox implored him to take Nikki to the hospital
    immediately.
    When Roberson arrived, Cox, who was in a wheelchair, took Nikki in her
    lap and they went to the emergency room. The nurses in the emergency room
    immediately began lifesaving measures.         It quickly became apparent to
    medical staff by the nature of Nikki’s injuries that something was amiss, and
    they called the police. A nurse specializing in sexual assault examinations,
    2
    Case: 14-70033      Document: 00513056841      Page: 3    Date Filed: 05/27/2015

    Andrea Sims, examined Nikki and noted injuries consistent with sexual
    assault, namely three tears on Nikki’s anus and abnormal rectal laxity. The
    CT scan performed at the hospital showed severe trauma to Nikki’s brain, and
    her doctors concluded that she needed to be transported to Children’s Medical
    Center in Dallas for further care. Nikki passed away in Dallas.
    Roberson was indicted for capital murder on April 25, 2002. Roberson
    was charged with two manner and means of committing the offense of capital
    murder: murder committed during the course of committing or attempting to
    commit aggravated sexual assault and murder of a child under the age of six
    years. 1 The Texas Court of Criminal Appeals summarized the testimony at
    trial in its opinion on direct appeal:
    The State called twelve witnesses during its case-in-chief.
    Among them was Kelly Gurganus, a registered nurse, who testified
    that she was working in the emergency room of the Palestine
    Regional Medical Center when [Roberson] came in, pushing a
    wheelchair in which sat his girlfriend Teddie Cox. Gurganus said
    Teddie was holding something in her lap, covered in a blanket or
    coat of some sort. Teddie told Gurganus, “She’s not breathing,” at
    which point Gurganus removed the covering and saw Nikki Curtis
    lying in Teddie’s lap, limp and blue. Gurganus described Nikki as
    being like a rag doll, and said that in her five years of nursing she
    had never seen anyone appear that shade of blue, not even a
    drowning victim. Gurganus immediately took Nikki to a trauma
    room and called a doctor.
    Gurganus further testified that when she laid Nikki down
    on the bed in the trauma room, she saw bruising on Nikki’s body,
    including on her head. She said that she then spoke with
    [Roberson] and asked him what happened, and that he told her
    that Nikki’s injuries were the result of falling off of the bed. She
    said she immediately became suspicious because that story
    seemed implausible in light of the severity of Nikki's injuries. She
    instructed the director of nurses to call the police.
    1 The capital murder statute has since been amended to include murder of a child
    under ten years old. Tex. Penal Code § 19.03(a)(8).

    No. 14-70033
    Gurganus spoke again with [Roberson] and said that he
    appeared nervous and anxious. She also said that he never once
    asked her about Nikki’s condition, and that he was not crying. She
    said that she attempted to speak with Nikki’s maternal
    grandparents, who had also come to the hospital, but that
    [Roberson] prevented her from doing so. That was the extent of
    her conversation with [Roberson], except that he did approach her
    at some point later to say he loved his daughter and that he would
    never mean to hurt her. The State also called Robbin Odem, the
    chief nursing officer at Palestine Regional Medical Center, who
    testified to her own observations of Nikki’s extensive head injuries,
    as well as her similar interaction with, and impression of,
    [Roberson] in the emergency room that night.
    Roberson v. State, No. AP-74671, 
    2002 WL 34217382
    , at *1 (Tex. Crim. App.
    June 20, 2007) (unpublished).      Next, the state called Andrea Sims, who
    testified in detail as to the results of her sexual assault examination and her
    conclusion that Nikki was likely sexually assaulted. The state then called
    Brian Wharton, one of the police officers who investigated Nikki’s death.
    Wharton testified that Roberson told him that Nikki had hurt herself by falling
    out of the bed. Wharton searched Roberson’s house with Roberson present and
    recovered a bloody wash rag and found blood on a pillow. Other than those two
    items, Wharton testified that they found no evidence indicating a violent
    struggle.     The state’s case continued with the testimony of one of Nikki’s
    physicians:
    Dr. John Ross, the pediatrician who examined Nikki the day
    she died, testified that she had bruising on her chin, as well as
    along her left cheek and jaw. Dr. Ross said she also had a large
    subdural hematoma, which he described as “bleeding outside the
    brain, but inside the skull.” He said there was edema on the brain
    tissue, and that her brain had actually shifted from the right side
    to the left. He said that, in his opinion, Nikki’s injuries were not
    accidental but instead intentionally inflicted.
    Dr. Thomas Konjoyan, the emergency room physician who
    treated Nikki the day she died, also testified that she had bruising
    on the left side of her jaw, and that she had uncal herniation, which
    is “essentially a precursor to brain death.” Dr. Konjoyan said that
    4
    Case: 14-70033     Document: 00513056841     Page: 5   Date Filed: 05/27/2015
    No. 14-70033
    the severity of the swelling in Nikki’s brain necessitated her
    transfer to the Children’s Medical Center in Dallas for pediatric
    neurosurgical services. He said that, in his opinion, it would be
    “basically impossible” for such an injury to have resulted from a
    fall out of bed. Dr. Jill Urban, a forensic pathologist for Dallas
    County, testified for the State that she performed the autopsy on
    Nikki and concluded that Nikki died as a result of “blunt force head
    injuries.”
    The jury also heard from Courtney Berryhill, Teddie Cox’s
    eleven-year-old niece, who testified that sometimes she spent the
    night at the home where [Roberson] lived with Teddie, Nikki, and
    Teddie’s ten-year-old daughter Rachel Cox. Courtney said that she
    once witnessed [Roberson] shake Nikki by the arms in an attempt
    to make her stop crying. Rachel Cox then testified that [Roberson]
    had a “bad temper,” and that she had witnessed him shake and
    spank Nikki when she was crying. Rachel said she had seen this
    happen about ten times. She also recalled a time that [Roberson]
    threatened to kill Nikki.
    Id. at *2. Dr. Janet Squires, a pediatrician who treated Nikki at Children’s
    Medical Center in Dallas, also testified for the state. Dr. Squires testified that
    the act that caused Nikki’s injuries was a “very violent forceful act,” an act
    “that any reasonable person would realize is not normal,” and that Nikki was
    the victim of “non-accidental inflicted trauma.” Dr. Squires, who was also the
    primary physician with Children’s Medical Center’s child abuse unit, testified
    that she observed only one small laceration on Nikki’s anus and that rectal
    laxity means very little in a totally comatose child. As such, Dr. Squires
    testified that she was not prepared to conclude one way or the other whether
    Nikki had been sexually abused. The state then called Teddie Cox:
    Teddie said that, although Nikki was not her biological child, she
    loved Nikki as her own. At the time she moved in with [Roberson],
    Nikki was living with her maternal grandparents, the Bowmans.
    Teddie said that [Roberson] had no interest in gaining custody of
    Nikki but did so only because Teddie wanted to care for Nikki, and
    so she—along with [Roberson]’s mother—prodded [Roberson] to
    seek custody of Nikki. They did, and Nikki came to live in their
    home in November of 2001. Teddie said that, although she and
    5
    Case: 14-70033   Document: 00513056841      Page: 6   Date Filed: 05/27/2015
    No. 14-70033
    Rachel were both very close with Nikki, [Roberson] was not, nor
    did he seem to care about her. She said that Nikki did not like to
    be around [Roberson] and would cry every time he tried to pick her
    up or play with her.
    Teddie testified that [Roberson] had a bad temper, and that
    he would yell at Nikki when she cried, which apparently happened
    every time he approached her. Teddie said she once heard
    [Roberson] yell at Nikki: “If you don’t shut up I’m going to beat
    your ass.” She also said that [Roberson] would hit Nikki with his
    hand and also once with a paddle. She said that on that occasion
    she told [Roberson] that he should not do that because Nikki was
    a baby. That whipping left bruising on Nikki’s buttocks which the
    Bowmans later noticed. Teddie said that, when the Bowmans
    asked about it, [Roberson] told them that Rachel did it. She said
    that she confronted [Roberson] about the incident and that he
    promised her he would never hit Nikki again.
    Teddie also testified that she witnessed [Roberson], when he
    was angry at Nikki, pick her up off the bed, shake her for a few
    seconds, and throw her back on the bed. This upset Teddie, and
    she briefly left [Roberson]’s home with Rachel, but [Roberson]
    apologized and convinced her to return. According to Teddie, this
    incident happened within a month of Nikki’s death.
    Teddie testified that, on the evening of January 30, 2002,
    Teddie was in the hospital after undergoing a hysterectomy
    procedure. Nikki was staying with the Bowmans, but Mrs.
    Bowman became ill, so it became necessary for [Roberson] to pick
    up Nikki and look after her. Teddie said [Roberson] seemed mad
    about this development, because he preferred to stay with her in
    her hospital room watching a movie on television. Teddie said
    [Roberson] had never once before been asked to be the sole
    caretaker of Nikki. She said [Roberson] did not leave immediately,
    but waited quite a while and, when he finally did leave, he was
    mad.
    The next morning, Teddie was told she was being released.
    When she spoke to [Roberson] about picking her up, he said that
    he was bringing Nikki to the hospital because she wasn’t breathing
    and he couldn’t get her to wake up. Teddie noted that he did not
    seem upset about the situation. She called him back five minutes
    later, but he still had not yet left the house, so she urged him to do
    so. She then went to the nurse’s desk to get a wheelchair so she
    could make her way downstairs to meet them as they arrived.
    6

    No. 14-70033
    [Roberson] eventually pulled into the parking lot. Teddie said he
    did not seem to be moving urgently and in fact found a parking
    spot instead of pulling up to the front door. Nor did he seem to be
    in any hurry to get Nikki out of the car.
    Teddie urged him to bring Nikki to her, and he did. Teddie
    said Nikki was limp, blue, and did not appear to be breathing.
    Teddie said she asked [Roberson] what happened, and he said that
    they had fallen asleep in bed while watching a movie and that he
    awoke to her crying near the foot of the bed, on the floor. He said
    he made sure that she was okay and then brought her back into
    bed with him, and they went back to sleep. Teddie said she was
    skeptical of this story, because, in her experience, Nikki would
    always cry for Teddie when [Roberson] tried to sleep in the bed
    with her. In fact, Teddie said, [Roberson] later did tell her that
    Nikki was crying for her.
    Nikki died from her injuries after being taken to the hospital
    in Dallas. Teddie could not accompany Nikki when she was taken
    to Dallas, but she did not want to return to [Roberson]’s home, so
    she took her daughter to stay with a relative. In the ensuing
    weeks, she spoke with [Roberson] occasionally, and she said he
    never once mentioned Nikki, and that when she did he expressed
    no interest in talking about her. Teddie said he did not seem sad
    or emotionally distraught, but that he just showed no interest. At
    one point, while [Roberson] was in the Anderson County Jail,
    Teddie said she asked him directly if he had killed Nikki. She said
    his response was that if he did do it, he didn’t remember; that he
    might have “snapped,” but that he doesn’t remember doing so.
    Id. at *2–*3. The state next called Dr. Jill Urban, who performed the autopsy
    on Nikki.   Dr. Urban testified as to her findings in the autopsy and her
    conclusion that Nikki died from blunt force head injuries, defined to include
    shaking. Dr. Urban testified that she found no injury to Nikki’s anus and that
    tests for semen and spermatozoa came back negative. Last, the state called
    Verna Bowman, Nikki’s maternal grandmother. Ms. Bowman described the
    custody battle between herself and Roberson’s mother, and explained that she
    and her husband ultimately reached an agreement when Roberson himself
    asked for custody. Ms. Bowman then gave her account of an incident described
    by other witnesses as well, in which Nikki had been spanked, leaving bruises
    7
    Case: 14-70033    Document: 00513056841     Page: 8   Date Filed: 05/27/2015
    No. 14-70033
    on her buttocks. Ms. Bowman testified that Roberson brought Nikki over and
    explained the bruising by blaming Rachel.         Ms. Bowman testified that
    Roberson’s explanation sounded strange. Ms. Bowman then recounted how
    she and her husband were asked to babysit Nikki while Cox was in the hospital
    for her surgery, and explained that she became sick and had to ask Roberson
    to come pick Nikki up. After Ms. Bowman’s testimony, the state rested.
    The defense case-in-chief then began with the testimony of “Patricia
    Conklin, Teddie’s sister, who testified that, in her opinion, [Roberson] had a
    loving relationship with Nikki.” Id. at *4. “She said that in her experience she
    had never seen [Roberson] spank Nikki, but that she had once seen Rachel do
    so.” Id. “She also said that, in her opinion, Teddie had a poor reputation for
    truthfulness.” Id. Roberson also attempted to call an expert witness in his
    defense, Dr. John Claude Krusz. Prior to his testifying, the state took Dr.
    Krusz on voir dire. Dr. Krusz testified during the state’s voir dire that he is a
    board certified neurologist who examined Roberson.        Dr. Krusz diagnosed
    Roberson with organic brain disorder, and more specifically post-concussional
    syndrome. Dr. Krusz testified that Roberson has an IQ of 85, poor impulse
    control, and difficulty making decisions. Dr. Krusz testified that the disorder
    interferes with Roberson’s reasoning ability, his ability to make rational
    decisions, and his ability to intentionally or knowingly carry out an act. During
    the voir dire, one of Roberson’s attorneys also questioned Dr. Krusz:
    Q.    Doctor, your opinions with respect to Robert’s
    condition, do you think that they would be of benefit to the jury in
    understanding Robert’s ability to deal with the situation of stress?
    A.    I believe they would.
    Q.    All right. And I reviewed with you what’s called
    culpable mental states that are recognized under law?
    A.    Yes.
    Q.    And this that you have found with Robert, does it have
    a direct relationship based upon reasonable medical probability
    8
    Case: 14-70033     Document: 00513056841       Page: 9   Date Filed: 05/27/2015
    No. 14-70033
    and established scientific grounds to kind of give an indication of
    how he performed relative to those culpable mental states?
    A.     Yes, I believe we have that information.
    The state then re-urged its objection, arguing that Dr. Krusz’s testimony
    amounted to a “diminished capacity” defense, not recognized under Texas law.
    The trial judge agreed and excluded Dr. Krusz’s testimony. Defense counsel
    further examined Dr. Krusz, however, as an offer of proof for their bill of
    exceptions. Defense counsel asked Dr. Krusz if Roberson would satisfy the
    legal definition of insanity:
    Q.     Okay. By the way, you are familiar with the legal
    standard for a person being established as insane, are you not?
    A.     Yes.
    Q.     That a person cannot tell right from wrong, cannot tell
    the significant character of his actions?
    A.     That’s correct.
    Q.     Would that type of level of insanity rise to Robert’s
    situation?
    A.     No, sir.
    Dr. Krusz then testified further:
    Q.    Okay. Say the situation were one was to take care of
    a small child who was ill, fussy, and you had no prior child caring
    capability or experience. Would that be a stressor that would
    affect Robert differently than normal individuals?
    A.    I believe it would, yes, sir.
    Q.    Okay. Would that effect be such that it would create
    an emotional control over his behavior?
    A.    I believe so, yes.
    Q.    Okay. You determined that there was some organic or
    actual brain injury?
    A.    Yes. My clinical diagnosis is that Mr. Roberson does
    have abundant evidence of traumatic brain injury or, as I
    mentioned earlier, post concessional syndrome.
    Q.    Okay. And this affects his reasoning capability?
    A.    Precisely. Specifically with respect to what we term
    inhibition of behaviors by frontal lobe [sic] of the brain.
    9

    No. 14-70033
    Q.  Okay. And you feel that this would be evidence that
    would aid a trier of fact in establishing or judging a person’s
    actions?
    A.  I believe it would.
    After concluding its offer of proof, the defense rested and both sides closed the
    evidence. Prior to closing arguments, the prosecution also expressly dropped
    the murder committed during the course of committing or attempting to
    commit aggravated sexual assault manner and means, sending only the
    murder of a child under six years old manner and means to the jury.
    The defense closing argument focused almost exclusively on raising
    reasonable doubt as to whether Roberson had the requisite culpable mental
    state at the time he killed Nikki.     The defense essentially conceded that
    Roberson’s story about Nikki falling off the bed was fabricated and instead
    argued that he did not intentionally or knowingly kill Nikki, the requisite mens
    rea for capital murder, and that one of the other homicide offenses under Texas
    law was a more appropriate punishment. The defense also argued that the
    evidence supporting sexual assault was so weak that the state had abandoned
    that manner and means.
    In its rebuttal, the state argued that the extent of Nikki’s injuries proved
    that Roberson knowingly and intentionally murdered Nikki. The state also
    argued that it had dropped the sexual assault manner and means only because
    the law required the state to elect one manner and means at the close of
    evidence—i.e., the law prohibited the state from sending both manner and
    means to the jury.
    The jury returned a verdict of capital murder. Roberson was sentenced
    to death.
    On direct appeal, Roberson raised two of the claims that are now before
    us. Rejecting Roberson’s claim that the trial court’s failure to sever the murder
    committed during the course of a sexual assault manner and means violated
    10
    Case: 14-70033     Document: 00513056841       Page: 11    Date Filed: 05/27/2015
    No. 14-70033
    the Texas Penal Code and the United States Constitution, the Court of
    Criminal Appeals stated, “[t]he indictment in this case did not allege two
    separate offenses, but rather one offense (capital murder) under two different
    theories (the victim was under six years of age, and the murder was committed
    in the course of committing aggravated sexual assault).” Id. at *6. As such,
    the court concluded that “[t]he trial court did not err by denying [Roberson]’s
    motion to sever under Section 3.04” of the Texas Penal Code and that the
    failure to sever did not “implicate, much less violate, any of [Roberson]’s federal
    constitutional rights.” Id. The Court of Criminal Appeals also confronted—
    and rejected—Roberson’s contention that the trial court’s exclusion of Dr.
    Krusz’s testimony violated his constitutional rights. The court noted that
    though “Texas does not recognize ‘diminished capacity’ as an affirmative
    defense, i.e., a ‘lesser form of the defense of insanity,’” the situation is different
    where “mental-health evidence is presented, not as part of an attempted
    affirmative defense, but instead as an attempt to negate the mens rea element
    of the charged offense,” and, under Texas law, “such evidence is admissible,
    assuming it meets the requirements of Rule 403.” Id. at *7 (quoting Jackson
    v. State, 
    160 S.W.3d 568
    , 573 (Tex. Crim. App. 2005)). The court concluded,
    however, that Dr. Krusz’s “proposed testimony regarding organic brain
    syndrome and poor impulse control is not relevant as to [Roberson]’s ability to
    form the requisite mens rea for the offense,” but rather “was merely being used
    as a mental-health defense not rising to the level of insanity.” Id. at *8.
    In December of 2004, Roberson filed an application for a writ of habeas
    corpus in state court. As to the first issue raised by Roberson herein, that the
    prosecutor violated his constitutional rights by proceeding to trial on the sexual
    assault manner and means when he knew it could not be proved beyond a
    reasonable doubt, the state court concluded that Roberson was “procedurally
    barred from asserting these complaints by way of the writ of habeas corpus
    11
    Case: 14-70033     Document: 00513056841     Page: 12   Date Filed: 05/27/2015
    No. 14-70033
    because he could have, but did not, raise the claim on direct appeal.”
    Alternatively, the court found and concluded “as a matter of law that
    [Roberson] has failed to state a claim upon which relief could be granted,
    because he has failed to state any constitutional basis upon which the
    prosecutor here could have been barred from proceeding to trial upon a valid
    indictment returned by the grand jury.” On appeal from the denial of the
    application for a writ of habeas corpus, the Texas Court of Criminal Appeals
    issued only a summary opinion, stating, in pertinent part:
    This Court has reviewed the record with respect to the allegations
    made by applicant. We adopt the trial judge’s findings of fact.
    Based upon the trial court’s findings and conclusions and our own
    review, the relief sought is denied.
    Ex parte Roberson, Nos. WR-63,081-01 & WR-63,081-02, 
    2009 WL 2959738
    , at
    *1 (Tex. Crim. App. Sept. 16, 2009) (unpublished) (per curiam).
    Roberson then filed a petition for a writ of habeas corpus in the United
    States District Court for the Eastern District of Texas. He alleged thirty-nine
    claims in his petition.     The report and recommendation issued by the
    magistrate judge recommended denial of Roberson’s petition.            Rejecting
    Roberson’s objections, the district court adopted the magistrate judge’s report
    and recommendation and also denied a certificate of appealability.
    Roberson has now applied to this court for a certificate of appealability
    on three of the thirty-nine issues raised in his petition. First, Roberson argues
    that the State violated his constitutional rights by presenting evidence as to
    the manner and means of murder committed during the course of a sexual
    assault in order to inflame the jury, with knowledge that the evidence was
    insufficient to support conviction.      Second, Roberson argues that the
    Constitution required the state court to sever the sexual assault manner and
    means for a separate trial.    Third, Roberson argues that the trial court’s
    12
    Case: 14-70033    Document: 00513056841      Page: 13    Date Filed: 05/27/2015
    No. 14-70033
    exclusion of Dr. Krusz’s testimony violated his Constitutional right to present
    a complete defense.
    II.
    Petitions for a writ of habeas corpus made by prisoners in state custody
    to federal courts are governed by the Anti-terrorism and Effective Death
    Penalty Act (“AEDPA”). 
    28 U.S.C. § 2254
    . Under AEDPA, a state prisoner is
    not entitled to a writ of habeas corpus from a federal court unless he
    demonstrates that the state court’s adjudication of his claim on the merits
    “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 “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). “A state court’s decision is
    contrary to clearly established federal law if the state court arrives at a
    conclusion opposite to that reached by the Supreme Court on a question of law
    or if the state court decides a case differently than the Supreme Court has on
    a set of materially indistinguishable facts.” Ward v. Stephens, 
    777 F.3d 250
    ,
    255 (5th Cir. 2015) (internal quotation marks and brackets omitted). “By
    contrast, a state court’s decision involves an unreasonable application of
    clearly established federal law if the state court identifies the correct governing
    legal principle from the Supreme Court’s decisions but unreasonably applies
    that principle to the facts of the prisoner’s case.” 
    Id.
     (internal quotation marks
    and brackets omitted). “The question under AEDPA is not whether a federal
    court believes the state court’s determination was incorrect but whether that
    determination was unreasonable—a substantially higher threshold.” Schriro
    v. Landrigan, 
    550 U.S. 465
    , 473 (2007). “This is a difficult to meet and highly
    deferential standard for evaluating state-court rulings, which demands that
    state-court decisions be given the benefit of the doubt.” Cullen v. Pinholster, -
    13
    Case: 14-70033    Document: 00513056841      Page: 14    Date Filed: 05/27/2015
    No. 14-70033
    -- U.S. ---, ---, 
    131 S. Ct. 1388
    , 1398 (2011) (citation and internal quotation
    marks omitted).
    Additionally, a claim procedurally defaulted on independent and
    adequate state law grounds by the petitioner in state court is generally not
    cognizable in federal district court. Coleman v. Thompson, 
    501 U.S. 722
    , 750
    (1991). In order to preclude federal review of the petitioner’s claim, the state
    procedural rule must be “adequate to support the judgment” and “firmly
    established and consistently followed.” Martinez v. Ryan, --- U.S. ---, ---, 
    132 S. Ct. 1309
    , 1316 (2012). The petitioner may avoid his procedural default by
    showing “‘cause for the default and prejudice from a violation of federal law.’”
    Trevino v. Thaler, --- U.S. ---, ---, 
    133 S. Ct. 1911
    , 1917 (2013) (quoting
    Martinez, 
    132 S. Ct. at 1316
    ). The petitioner may also overcome the procedural
    default by showing that “the failure to consider his claims would result in a
    fundamental miscarriage of justice because he is ‘actually innocent’ of the
    offense underlying his conviction or ‘actually innocent’ of the death penalty.”
    Roberts v. Thaler, 
    681 F.3d 597
    , 605 (5th Cir. 2012).
    Further, AEDPA restricts a petitioner’s right to appeal a federal district
    court’s denial of his petition for a writ of habeas corpus. Miller-El v. Cockrell,
    
    537 U.S. 322
    , 335 (2003). In order to appeal, the petitioner must first obtain a
    certificate of appealability from a circuit judge or justice.           
    28 U.S.C. § 2253
    (c)(1). A certificate of appealability “may issue . . . only if the applicant
    has made a substantial showing of the denial of a constitutional right.” 
    28 U.S.C. § 2253
    (c)(2). “‘A petitioner satisfies this standard by demonstrating
    that jurists of reason could disagree with the district court’s resolution of his
    constitutional claims or that jurists could conclude the issues presented are
    adequate to deserve encouragement to proceed further.’” United States v.
    Fields, 
    761 F.3d 443
    , 451 (5th Cir. 2014) (quoting Miller-El, 
    537 U.S. at 327
    ).
    “To obtain a COA when the district court has denied relief on procedural
    14
    Case: 14-70033     Document: 00513056841      Page: 15   Date Filed: 05/27/2015
    No. 14-70033
    grounds, such as procedural default, a petitioner must show both a debatable
    claim on the merits and that the district court’s procedural ruling is
    debatable.”   Garza v. Stephens, 
    738 F.3d 669
    , 673 (5th Cir. 2013).          “The
    question of whether a COA should issue is a threshold inquiry that requires an
    overview of the claims in the habeas petition and a general assessment of their
    merits;” “[a] full consideration of the merits is neither required nor permitted.”
    Ruiz v. Stephens, 
    728 F.3d 416
    , 423 (5th Cir. 2013) (footnote and internal
    quotation marks omitted). But the “determination of whether a COA should
    issue must be made by viewing the petitioner’s arguments through the lens of
    the deferential scheme laid out in 
    28 U.S.C. § 2254
    (d).” Ward, 777 F.3d at 255
    (internal quotation marks omitted). Nevertheless, in a death penalty case, any
    doubts as to whether a certificate of appealability should issue are resolved in
    favor of the petitioner. United States v. Bernard, 
    762 F.3d 467
    , 471 (5th Cir.
    2014).
    III.
    Roberson’s first claim is that his due process and fair trial rights were
    violated by the prosecutor’s actions in trying him on the murder committed “in
    the course of committing or attempting to commit . . . aggravated sexual
    assault” theory of capital murder in addition to the murder of a child under the
    age of six theory. Tex. Penal Code § 19.03(a)(2). Roberson argues that the
    prosecutor knew that he could not prove the aggravated sexual assault theory,
    but argued the theory merely to prejudice Roberson and inflame the jury. We
    do not address the merits of this argument, or its underlying theory, as this
    claim is procedurally defaulted on an independent and adequate state law
    ground.
    The state district court held that Roberson defaulted this claim by failing
    to raise it on direct appeal. The state court here expressly relied on Roberson’s
    failure to raise his claim on direct appeal and concluded that the claim was
    15
    Case: 14-70033     Document: 00513056841      Page: 16   Date Filed: 05/27/2015
    No. 14-70033
    defaulted. We presume that failure to raise a claim on direct appeal is an
    independent and adequate state law grounds for procedural default, and
    Roberson makes no argument to rebut that presumption. See Sones v. Hargett,
    
    61 F.3d 410
    , 416 (5th Cir. 1995) (“We presume the adequacy and independence
    of a state procedural rule when the state court expressly relies on it in deciding
    not to review a claim for collateral relief, as the Mississippi Supreme Court did
    here.”); Moore v. Roberts, 
    83 F.3d 699
    , 702 (5th Cir. 1996). Roberson’s only
    argument as to the direct appeal procedural default is that there was cause
    and prejudice by virtue of his direct appellate counsel’s ineffective assistance.
    Assuming without deciding that Roberson’s direct appellate counsel’s
    ineffective assistance could provide cause to excuse the procedural default of
    this claim, Roberson has wholly failed to make such a showing. In order to
    show ineffective assistance of counsel on direct appeal, Roberson must show
    that his appellate counsel’s performance was deficient and that the deficient
    performance caused him prejudice. Dorsey v. Stephens, 
    720 F.3d 309
    , 319 (5th
    Cir. 2013); see also 
    id.
     (stating that claims of ineffective assistance of counsel
    on direct appeal are governed by the two-part standard set out in Strickland
    v. Washington, 
    466 U.S. 668
     (1984)). “[C]ounsel should be ‘strongly presumed
    to have rendered adequate assistance and made all significant decisions in the
    exercise of reasonable professional judgment.’” Pinholster, --- U.S. at ---, 
    131 S. Ct. at 1403
     (quoting Strickland, 
    466 U.S. at 690
    ). In order to be considered
    ineffective, the attorney must have “made errors so serious that counsel was
    not functioning as the ‘counsel’ guaranteed the defendant by the Sixth
    Amendment.” Strickland, 
    466 U.S. at 687
    . Roberson has wholly failed to
    demonstrate deficient performance by his attorney on direct appeal. To show
    ineffective assistance, Roberson points only to the bare fact that his attorney
    did not raise on direct appeal the argument he now puts forward. But the mere
    fact that his attorney did not raise an argument is insufficient to show that his
    16
    Case: 14-70033     Document: 00513056841      Page: 17   Date Filed: 05/27/2015
    No. 14-70033
    attorney’s decision not to do so was deficient. See Smith v. Robbins, 
    528 U.S. 259
    , 288 (2000) (“[A]ppellate counsel who files a merits brief need not (and
    should not) raise every nonfrivolous claim, but rather may select from among
    them in order to maximize the likelihood of success on appeal.”); Dorsey, 720
    F.3d at 320 (“When, as here, counsel files a merits brief, a defendant generally
    must show that ‘a particular nonfrivolous issue was clearly stronger than
    issues counsel did present.’” (quoting Robbins, 
    528 U.S. at 288
    )); 
    id.
     (“There is
    a strong presumption that counsel’s attention to certain issues to the exclusion
    of others reflects trial tactics rather than sheer neglect.” (internal quotation
    marks omitted)). Given Roberson’s total lack of argument that his direct
    appellate counsel’s performance fell outside the realm of “the exercise of
    reasonable professional judgment,” Pinholster, --- U.S. at ---, 
    131 S. Ct. at 1403
    (internal quotation marks omitted), he has failed to show cause and prejudice
    with regard to his procedural default of his first claim. As such, reasonable
    jurists could not debate that the district court’s disposition of this claim was
    proper.
    IV.
    Roberson’s second claim is that his procedural due process rights and his
    right to a fair trial were violated by trying him on the two theories of capital
    murder—murder committed during an aggravated sexual assault and murder
    of a child—in one trial. Roberson contends that, given the incendiary nature
    of the murder committed during an aggravated sexual assault theory, the
    Constitution requires two separate trial to avoid jury prejudice. We deny a
    certificate of appealability on this point, as reasonable jurists would not debate
    the district court’s rejection of Roberson’s contention.
    As support for his argument, Roberson cites State v. Boscarino, 
    529 A.2d 1260
     (Conn. 1987), a Connecticut Supreme Court case. But Boscarino provides
    Roberson with no support whatsoever for overcoming the burden of AEDPA.
    17
    Case: 14-70033    Document: 00513056841       Page: 18   Date Filed: 05/27/2015
    No. 14-70033
    No matter the persuasiveness of the Connecticut Supreme Court’s opinion in
    Boscarino, state court decisions do not constitute “clearly established Federal
    law, as determined by the Supreme Court of the United States.” 
    28 U.S.C. § 2254
    (d)(1) (emphasis added); cf. Parker v. Matthews, --- U.S. ---, ---, 
    132 S. Ct. 2148
    , 2155 (2012) (“[C]ircuit precedent does not constitute ‘clearly established
    Federal law, as determined by the Supreme Court,’ 
    28 U.S.C. § 2254
    (d)(1). It
    therefore cannot form the basis for habeas relief under AEDPA.”). Boscarino
    is also wholly distinguishable. First, the court in Boscarino was applying
    Connecticut law, not the United States Constitution. Boscarino, 529 A.2d at
    1264.    Second, in Boscarino, the defendant was jointly tried for separate
    criminal incidents, four sexual assaults of four separate victims on four
    different dates. Id. at 1262. Here, by contrast, there was only one criminal
    incident—one capital murder of one victim—but two separate and alternative
    statutory aggravating elements alleged.           Boscarino is, therefore, not
    instructive.
    Roberson also cites four Supreme Court cases in support of his
    argument—Crane v. Kentucky, 
    476 U.S. 683
     (1986); Washington v. Texas, 
    388 U.S. 14
     (1967); California v. Trombetta, 
    467 U.S. 479
     (1984); and Chambers v.
    Mississippi, 
    410 U.S. 284
     (1973). All four of those cases, however, address state
    courts’ limitations on a defendant’s ability to introduce evidence to defend
    against the criminal charges brought against him. See Crane, 
    476 U.S. at
    690–
    91 (holding that the state court’s exclusion of evidence probative of the
    credibility of the defendant’s confession because the proffered evidence was
    also relevant to voluntariness, an issue the court had already ruled on, violated
    the defendant’s right to a fair trial under the Sixth and Fourteenth
    Amendments); Washington, 
    388 U.S. at 15, 23
     (holding that a state statute
    barring the defendant from calling a “principal[], accomplice[], or accessor[y]
    in the same crime” as a witness in his defense violated the defendant’s rights
    18
    Case: 14-70033    Document: 00513056841      Page: 19   Date Filed: 05/27/2015
    No. 14-70033
    to call witnesses in his own defense and to compulsory process for obtaining
    such witnesses); Trombetta, 
    467 U.S. at 491
     (holding that the Constitution does
    not require the state to preserve a breath sample used in a breath-analysis test
    in a DUI prosecution); Chambers, 
    410 U.S. at
    295–98, 302–03 (holding that the
    Mississippi voucher and hearsay rules were unconstitutional as applied to the
    extent that they prevented the defendant from: (1) putting on evidence of a
    third party’s confession to the crime with which the defendant was charged
    and (2) challenging that witness’s subsequent retraction). None of these cases
    holds that a state court is constitutionally required to sever different manner
    and means of committing a single offense for separate trials. One Supreme
    Court case not cited by Roberson, United States v. Lane, 
    474 U.S. 438
     (1986),
    comments in a footnote that “[i]mproper joinder does not, in itself, violate the
    Constitution,” but states that “misjoinder would rise to the level of a
    constitutional violation only if it results in prejudice so great as to deny a
    defendant his Fifth Amendment right to a fair trial.” 
    Id.
     at 446 n.8. The
    Supreme Court has not since expanded on its statement in Lane. Aside from
    our grave doubts that two sentences of dicta in a footnote could constitute
    “clearly established Federal law, as determined by the Supreme Court,” 
    28 U.S.C. § 2254
    (d)(1), Lane involved joinder of a separate incident of mail fraud
    alleged against only one of the defendants, 
    474 U.S. at 442
    . It is therefore
    wholly distinguishable from the present case where there were not two
    charges, but two manner and means of committing the same offense—the
    murder of a single individual by a single defendant. As such, reasonable jurists
    would not debate the district court’s determination that Roberson has failed to
    show that the Texas court’s decision was contrary to or an unreasonable
    application of clearly established Federal law, as interpreted by the Supreme
    Court.
    19
    Case: 14-70033       Document: 00513056841     Page: 20    Date Filed: 05/27/2015
    No. 14-70033
    V.
    Roberson’s third contention is that the state trial court’s exclusion of his
    expert witness’s testimony violated his due process rights and his right to
    present witnesses in his own defense. Roberson argues that the testimony of
    that expert, Dr. Krusz, was relevant as it tended to show that he did not act
    intentionally or knowingly in killing his daughter, an element the state had
    the burden to prove beyond a reasonable doubt. See Tex. Penal Code § 19.03(a);
    Tex. Penal Code § 19.02(b)(1). The state argues that Roberson’s argument is
    foreclosed by Clark v. Arizona, 
    548 U.S. 735
     (2006), in which the Supreme
    Court upheld an Arizona law channeling all expert mental health testimony
    into the insanity defense and precluding its admission to negate mens rea. See
    
    id. at 779
     (“Arizona’s rule serves to preserve the State’s chosen standard for
    recognizing insanity as a defense and to avoid confusion and misunderstanding
    on the part of jurors. For these reasons, there is no violation of due process . . .
    and no cause to claim that channeling evidence on mental disease and capacity
    offends any principle of justice so rooted in the traditions and conscience of our
    people as to be ranked as fundamental.” (internal quotation marks and
    footnote omitted)). The citation to Clark, however, misses the mark, because
    Texas has not adopted a rule akin to Arizona’s, as the Texas Court of Criminal
    Appeals acknowledged in this case. See Roberson, 
    2002 WL 34217382
    , at *8.
    Instead, Texas allows evidence that is “presented, not as part of an attempted
    affirmative defense, but instead as an attempt to negate the mens rea element
    of the charged offense,” “assuming it meets the requirements of Rule 403.” Id.
    at *7.    The Texas Court of Criminal Appeals, on direct appeal, held that the
    testimony of Dr. Krusz was properly excluded not because of a categorical rule
    like that in Clark, and not because the evidence ran afoul of Rule 403, but
    because it was “not relevant as to the appellant’s ability to form the requisite
    mens rea for the offense.” Id. at *8. The court held instead that the expert
    20
    Case: 14-70033    Document: 00513056841     Page: 21   Date Filed: 05/27/2015
    No. 14-70033
    testimony “was merely being used as a mental-health defense not rising to the
    level of insanity.” Id.
    The Supreme Court has made clear that “[t]he Constitution guarantees
    criminal defendants a meaningful opportunity to present a complete defense”
    and that “evidence rules that infringe upon a weighty interest of the accused
    and are arbitrary or disproportionate to the purposes they are designed to
    serve” infringe that right. Holmes v. South Carolina, 
    547 U.S. 319
    , 324 (2006)
    (internal quotation marks and brackets omitted).           Roberson, of course,
    ultimately bears the burden of persuading us that Dr. Krusz’s testimony was
    substantial enough that its exclusion constituted an “unreasonable application
    of, clearly established Federal law, as determined by the Supreme Court of the
    United States.” 
    28 U.S.C. § 2254
    (d)(1). Yet the issue is debatable by jurists of
    reason. Accordingly, we GRANT a certificate of appealability as to Issue Three.
    VI.
    For the reasons stated above, Roberson’s application for a certificate of
    appealability is DENIED as to Issues One and Two and GRANTED as to Issue
    Three. The Clerk is ORDERED to establish a briefing schedule directed to
    Issue Three.
