Jaime Lorenzo Dozal-Vargas appeals his sentence following his guilty plea conviction for illegal reentry into the United States in violation of 8 U.S.C. § 1326. Do-zal-Vargas was sentenced at the bottom of his advisory guidelines range to 46 months of imprisonment and two years of supervised release. He argues that his sentence is substantively unreasonable because it is greater than necessary to satisfy the sentencing goals of 18 U.S.C. § 3553(a). He contends that his sentence overstates the seriousness of the offense of conviction, fails to account for his personal history and characteristics, is based on a Guideline that is not empirically based, and produced an unwarranted sentencing disparity.

Dozal-Vargas’s argument regarding the validity of the Sentencing Guideline at issue, namely, U.S.S.G. § 2L1.2, is foreclosed in this court. See United States v. Duarte, 569 F.3d 528, 529-31 (5th Cir.), cert. denied, — U.S.-, 130 S.Ct. 378, 175 L.Ed.2d 231 (2009). His argument that the Guidelines produce unwarranted sentencing disparities between defendants who can participate in a fast-track program and defendants who cannot is also foreclosed in this court. See United States *513 v. Gomez-Herrera, 523 F.3d 554, 563 (5th Cir. 2008).

The substantive reasonableness of Do-zal-Vargas’s sentence is reviewed for plain error because he did not object on that ground in the district court. See United States v. Whitelaw, 580 F.3d 256, 259-60 (5th Cir. 2009); United States v. Peltier, 505 F.3d 389, 391-92 (5th Cir. 2007). His arguments are insufficient to overcome the presumption of reasonableness afforded his within guidelines sentence. See, e.g., Gomez-Herrera, 523 F.3d at 565-66; United States v. Rodriguez, 523 F.3d 519, 526 (5th Cir. 2008). He has failed to establish that his sentence was the result of error, much less plain error. See Gall v. United States, 552 U.S. 38, 51, 128 S.Ct. 586, 169 L.Ed.2d 445 (2007); Duarte, 569 F.3d at 529-31 & n. 11.

AFFIRMED.
