Former Rep. Todd Tiahrt (Jason Horowitz, Washington Post)

Part of the Kansas delegation nominating Mitt Romney: former Rep. Todd Tiahrt, sporting a giant fake mustache. Tiahrt lost a 2010 Republican Senate primary and decided not to run for his old House seat; he now runs an aviation industry consulting firm. Oh, and dresses up as Wyatt Earp. In an interview with New York Magazine, he explained that he's doing it for a friend.
