Does 18 U.S.C. § 2252A violate the Due Process Clause and the void-for-vagueness doctrine?

QUESTION PRESENTED Does 18 U.S.C. § 2252A violate the Due Process Clause and the doctrine because the statute allows a prosecutor to unilaterally select not only the statutory maximum sentence but also the statutory mandatory minimum sentence by choosing to charge either receipt or possession of child pornography when there is no difference between the two offenses, and the two offenses involve the same conduct and the same harm? 1
