Alejandro Cardenas appeals his sentence of two concurrent 80-month terms of imprisonment imposed for his guilty-plea conviction of importation of marijuana and possession with the intent to distribute marijuana. Cardenas challenges the constitutionality of the treatment of his prior drug convictions as sentencing factors rather than offense elements that must be found by a jury in light of Apprendi v. New Jersey, 530 U.S. 466, 120 S.Ct. 2348, 147 L.Ed.2d 435 (2000).

Cardenas’s constitutional challenge is foreclosed by Almendarez-Torres v. United States, 523 U.S. 224, 235, 118 S.Ct. 1219, 140 L.Ed.2d 350 (1998). Cardenas contends that Almendarez-Torres was incorrectly decided and a majority of the current Court would overrule it in the light of Apprendi and subsequent Supreme Court authority. We have repeatedly re *388 jected such contentions because Almendarez-Torres remains binding. See United States v. Garza-Lopez, 410 F.3d 268, 276 (5th Cir.), cert. denied, — U.S.-, 126 S.Ct. 298, 163 L.Ed.2d 260 (2005). Cardenas properly concedes that his argument is foreclosed in light of Almendarez-Torres, but he raises it here to preserve it for further review.

Cardenas also argues that the district court committed plain error by failing to ask whether he affirmed or denied his prior convictions, as required by 21 U.S.C. § 851(b). Because Cardenas has not alleged that he did not commit the prior offenses or that the convictions were unconstitutionally obtained, he has not shown plain error. See United States v. Thomas, 348 F.3d 78, 86-87 (5th Cir. 2003).

AFFIRMED.
