Dexter Darnell Hewitt appeals from his jury verdict conviction for possession with *543 intent to distribute at least 5 grams of crack cocaine within 1,000 feet of a playground pursuant to 21 U.S.C. §§ 841 and 860(a). He was sentenced to 286 months of imprisonment, eight years of supervised release, and a $2,000 fíne.

Hewitt argues that § 860, as applied to him in this case, was not a valid constitutional exercise of federal authority by the United States Congress because it does not require a nexus with interstate commerce or regulate a commercial activity. His argument is foreclosed by this court’s holding in United States v. Dixon, 132 F.3d 192, 202 (5th Cir. 1997).

Next, Hewitt asserts that the evidence produced at trial was insufficient to support the jury’s verdict. Because Hewitt failed to preserve this challenge for appeal, our “review is limited to determining whether there was a manifest miscarriage of justice, that is, whether the record is devoid of evidence pointing to guilt.” United States v. Delgado, 256 F.3d 264, 274 (5th Cir. 2001) (citations and internal quotations marks omitted). However, our review of the evidence shows that it was sufficient to support the jury’s verdict even if Hewitt’s challenge had been preserved. See Jackson v. Virginia, 443 U.S. 307, 318, 99 S.Ct. 2781, 61 L.Ed.2d 560 (1979).

The judgment of the district court is AFFIRMED.
