. We note that the district court, having rejected the as-applied vagueness challenge, need not have addressed the facial vagueness challenge at all. See Holder v. Humanitarian Law Project, - U.S. -, 130 S.Ct. 2705, 2719, 177 L.Ed.2d 355 (2010) (explaining that "the rule that ‘a plaintiff who engages in some conduct that is clearly proscribed cannot complain of the. vagueness of the law as applied to the conduct of others' ... makes no exception for conduct in the form of speech”) (quoting Hoffman Estates v. Flipside, Hoffman Estates, Inc., 455 U.S. 489, 495, 102 S.Ct. 1186, 71 L.Ed.2d 362 (1982) (alteration omitted)); U.S. v. Di Pietro, 615 F.3d 1369, 1371-72 (11th Cir. 2010) (same).

. At oral argument for the first time, Plaintiff attempted to draw a distinction between the specific disclosure requirements at issue in Citizens United and those at issue in this case. Even at oral argument Plaintiff made only conclusory assertions without pointing to any specific disclosure requirement at issue here that was more onerous than those in Citizens United. However, we need not examine that possibility, because any such argument has not been preserved for appeal and is deemed abandoned. See Access Now, Inc. v. Southwest Airlines Co., 385 F.3d 1324, 1330 (11th Cir. 2004). Indeed, any such argument would also be inconsistent with Plaintiff's concession, both in the district court and in its initial brief on appeal, that Plaintiff was not challenging the disclosure requirements.
