USA Today asked its parent companies 35 actual Heisman voters how they would vote.  Geno Smith took all 35 first place votes.  Not much of a surprise.  However, Braxton Miller was 2nd with 18 2nd place votes and 7 3rd place votes.  That surprised me a bit given Ohio State's real lack of national publicity given the post season ban.  3rd on the list was Collin Klein from Kansas State, again another surprise since no one is talking about Kansas State at all.
