Finally, Congress's conclusion that “purveyors of child pornography usually cater to pedophiles, who by definition have a predilection for pre-pubertal children” further suggests the legitimate sweep of the CPPA far exceeds the threat of improper applications.
Id. “Even where a statute at its margins infringes on protected expression, facial invalidation is inappropriate if the remainder of the statute ... covers a whole range of easily identifiable and constitutionally proscribable ... conduct....”
Osborne, 495 U.S. at 112, 110 S.Ct. at 1697 (internal quotation marks and citation omitted). The CPPA undoubtedly captures a broad range of images falling squarely within the well-established parameters of constitutionally proscribable child pornography. Since the demand driving the child pornography market is primarily for images falling far from any constitutional protection, we conclude the legitimate scope of the statute dwarfs the risk of impermissible applications.
