Texas prisoner John L. Wheat seeks a certificate of appealability to challenge the district court’s denial of his 28 U.S.C. § 2254 petition for a writ of habeas corpus. Wheat was convicted of capital murder in violation of Tex. Penal Code Ann. § 19.03(a)(8) and sentenced to death. The Texas Court of Criminal Appeals affirmed his conviction on direct appeal. State ha-beas counsel was appointed, but relief was *359 denied by both the trial court and the Texas Court of Criminal Appeals. Wheat then filed an application for a writ of habe-as corpus for relief from the judgment of the state court under § 2254(a). The district court disposed of all claims and denied this writ, as well as subsequently denying the required certificate of appeal-ability (COA). Wheat now appeals this decision, presenting seven arguments as to why habeas relief is proper. Because these arguments either lack merit or are not properly considered on collateral review, we deny Wheat’s motion for a COA.

John Wheat was a neighbor of Angela Anderson and her three children — seven-year-old Eddie, six-year-old Ashley, and nineteen-month-old Lacey — in the Les Jardins apartment complex in Fort Worth. Angela relied on neighbors in the complex, including Wheat, to babysit her children when she worked night shifts on an assembly line. On the evening of July 25, 1995, Wheat watched Eddie and Ashley, while another neighbor took care of Lacey. The next morning, Ashley told her mother that Wheat had kissed her on the lips and touched her vagina. Angela reacted by instructing her son to deliver a handwritten note to Wheat that read as follows:
Ashley said you put your hand on her private (in her shorts) part. What the fuck? I will be calling the police! (emphasis in original).
Angela then started upstairs to use a telephone to report the incident to the police. As she left her apartment, Wheat came around the corner and began firing a .45 automatic pistol, chasing her upstairs. Injured, Angela fled into another apartment to rest momentarily. Wheat entered this apartment’s open front door, chased Angela into the rear bedroom, and with a .22 caliber derringer shot her twice in the head, though not fatally. Wheat then reloaded the automatic pistol and returned to Angela’s apartment, where he shot to death her three children.
Hearing gunfire, the apartment security officer went outside to investigate. Wheat shot at him, grazing his head. The security officer went back inside the apartment, but Wheat also shot through the door three times, further injuring the officer. Wheat also shot a police officer who responded to the police dispatch, inflicting a life-threatening injury.
Wheat was convicted of capital murder for the killing of the infant, Lacey, and sentenced to death. Wheat offers seven arguments in favor of his motion for a COA: (1) that the Texas death penalty scheme is unconstitutional in that it prevents defendants from offering evidence of parole ineligibility to juries considering the factor of future dangerousness; (2) that the trial court erred by excluding expert testimony that Wheat would probably not live long enough to qualify for release on parole; (3) that the trial court erred by disallowing Wheat to voir dire potential jurors regarding the forty-year parole ineligibility in Texas for life sentences for capital murder; (4) that there was insufficient evidence to support the jury finding of future dangerousness; (5) that the trial court erred by granting the State’s challenge for cause to a venire member for his professed aversion to the death penalty; (6) that he was deprived of his right to effective assistance of counsel when his lawyer failed to present a defense of insanity at the guilt-or-innocence phase of his trial; and (7) that the Texas Court of Criminal Appeals erred in state habeas proceedings by refusing to consider a supplement to Wheat’s original state writ application that would have brought out an argument of ineffective assistance of counsel.
To obtain a COA, Wheat must make a substantial showing of the denial of a constitutional right.
See
28 U.S.C. § 2253(c)(2). This standard is met if Wheat demonstrates that “ ‘reasonable jurists could debate whether (or, for that matter agree that) the petition should have
*360
been resolved in a different manner or that the issues presented were adequate to deserve encouragement to proceed further.’ ”
Barrientes v. Johnson,
II
Several of Wheat’s claims are procedurally barred. Wheat’s arguments of insufficient evidence to prove the probability of future dangerousness, and erroneous granting of the State’s for-cause challenge to a venire member were not raised on direct appeal. In his habeas petition, Wheat has made no attempt to argue cause and prejudice for the procedural default, so that the arguments are not properly considered on habeas review.
See Keeney v. Tamayo-Reyes,
Wheat’s argument regarding the alleged improper exclusion of expert testimony that Wheat would probably not live long enough to qualify for parole is also procedurally barred. Wheat raised this argument on direct appeal, whei-e the court found that the issue was not preserved during Wheat’s trial.
The intended offer of proof on the issue at the punishment phase went as follows:
A [by Dr. Mills]: I don’t feel I was able to give full meaning to my opinion regarding future dangerousness because of my inability or instructions not to discuss the parole issue. I believe that Mr. Wheat will not live 40 years. His physical health is bad and he has deteriorated over the last year. He is very likely to end up needing a nursing home in the future. And his life expectancy is essentially impossible to reach the age of 90.
Q [by defense counsel]: That’s approximately the age, 90 or 93, when Mr. Wheat, if in fact he received a life sentence, would only become eligible for parole.
A: That’s correct.
Q: To what degree or percentage can you say for the record was the impact of your testimony reduced by regarding future dangerousness without being able to discuss this factor before the jury?
A: I would say 50 percent.
Mr. Ford: That’s our offer of proof, Judge.
The Court: Let me add that I think there are some questions in there that I would permit you to ask him in front of the jury. I don’t know exactly what you’re seeking to offer.
Mr. Ford: That’s okay, Judge. I just wanted that on the record as our offer of proof.
We agree with the Texas Court of Criminal Appeals that the offer of proof was not properly preserved because without clarification by defense counsel it was impossible to determine which testimony the trial court allegedly erroneously excluded. Wheat again makes no attempt on appeal to show either cause or prejudice for this procedural default; he is therefore barred from now bringing the claim on federal habeas review.
See, e.g., Sharp v. Johnson,
Finally, Wheat argues that he was deprived of effective assistance "of counsel when the Court of Criminal Appeals during state habeas proceedings refused to consider a supplement to his original state writ application. Wheat contends
*361
that this supplement would include an affidavit from Wheat’s counsel acknowledging his own ineffective assistance for failing to preserve an issue (related to future dangerousness) for appeal, as well as the Court of Criminal Appeals’ criticism of counsel for this failure. The district court ruled that “[t]here is simply no authority to support the proposition that a petitioner has a constitutional right to have untimely submitted materials considered on their merits,” citing
Coleman v. Thompson,
Ill
Wheat argues that the Texas death penalty scheme violates the Fifth, Eighth, and Fourteenth Amendments to the extent that it prevents juries from considering the mitigating circumstances that dictate against the imposition of the death penalty. Fifty-three-year-old WTieat argues that the mitigating circumstances in his case are that there is an exceedingly low probability that, given his forty-year parole ineligibility on a life sentence, he would constitute a continuing threat to society. Wheat therefore analogizes his case to
Simmons v. South Carolina,
The district court found that this argument would ask the court to adopt a new rule of constitutional law, so that the claim is Teague-barred, regardless of the merits.
Teague v. Lane,
Under
Teague,
a federal court may not create new' constitutional rules of criminal procedure on habeas review.
See Teague,
IV
In a related claim, Wheat argues that his Fifth, Sixth, Eighth, and Fourteenth Amendment rights were violated when the trial court denied his motion to examine potential jurors regarding the forty-year parole ineligibility for life sentences for capital murder. Wheat asserts that his ability to exercise peremptory challenges, as well as the court’s ability to fulfill its obligation to remove prospective jurors, was impaired when he was unable to question jurors regarding parole eligibility. In
King v. Lynaugh,

Wheat next argues that his court-appointed trial counsel violated his Sixth Amendment right to the effective assistance of counsel by failing to present an insanity defense at the guilt-or-innocence phase of the trial. Wheat asserts that if called, the court-appointed psychiatrist would have testified that Wheat was legally insane at the time of the offense. Wheat contends that because the insanity defense was the only viable defense available to him, trial counsel’s error rises to the level of a constitutional deprivation.
The district court, following an evidentiary hearing on this issue, rejected the ineffective assistance of counsel claim. We review this decision
de novo
because ineffective assistance of counsel is a mixed question of law and fact.
See Crane v. Johnson,
It is true that there is some evidence that Wheat suffers from a mental deficiency. Specifically, the court-appointed psychiatrist testified in the punishment phase that Wheat was delusional shortly after his arrest, that magnetic resonance imaging of his brain revealed a large empty pocket in the base of his brain, that Wheat suffers *363 from Subcortical White Matter Disease (perhaps caused by workplace exposure to toluene), and that this brain damage was in a region that regulates impulsiveness, aggression, and violence. This psychiatrist, Dr. Mills, asserts that if called during the guilt-or-innocence stage of the trial, he would have testified that Wheat was legally insane at the time of the offense.
Wheat’s trial counsel, however, investigated the possibility of an insanity defense and made a tactical choice to reserve the doctor’s testimony until the punishment phase.
See Williams v. Cain,
VI
For the foregoing reasons, Wheat’s request for a certificate of appealability is DENIED.
