Raymondo Acuna appeals his above-guidelines prison sentence for possession with intent to distribute a controlled substance. He argues that his sentence violates the Eighth Amendment because the sentence is grossly disproportionate to the seriousness of his crime of conviction and thus constitutes cruel and unusual punishment. We review his constitutional claim de novo. United States v. Romero-Cruz, 201 F.3d 374, 377 (5th Cir. 2000).

Acuna’s assertion that his sentence violates the Eighth Amendment’s prohibition against cruel and unusual punishment is without merit. The Eighth Amendment prohibits a sentence that is grossly disproportionate to the severity of the crime for which it is imposed. Solem v. Helm, 463 U.S. 277, 288, 103 S.Ct. 3001, 77 L.Ed.2d 637 (1983). When evaluating an Eighth Amendment proportionality challenge, we make a threshold comparison between the gravity of the charged offense and the severity of the sentence. McGruder v. Puckett, 954 F.2d 313, 315 (5th Cir. 1992). We look to Rummel v. Estelle, 445 U.S. 263, 100 S.Ct. 1133, 63 L.Ed.2d 382 (1980), as a benchmark. United States v. Gonzales, 121 F.3d 928, 943 (5th Cir. 1997), abrogated on other grounds by United States v. O’Brien, 560 U.S. 218, 130 S.Ct. 2169, 176 L.Ed.2d 979 (2010).

The 200-month prison sentence is not grossly disproportionate to the severity of Acuna’s drug offense when measured against the benchmark in Rmnmel, See 445 U.S. at 284-85,100 S.Ct. 1133. Accordingly, Acuna’s Eighth Amendment claim fails. See McGruder, 954 F.2d at 315-17.

AFFIRMED.
