Former Republican presidential candidate and pizza magnate Herman Cain had said that he would not challenge Chambliss in a Republican primary, but his calculus may change now that the incumbent is off the ballot. Cain unsuccessfully ran for the seat in 2004.
Despite running one of the strangest presidential campaigns in history — which ended in a surreal collapse featuring allegations of sexual harassment and frequent quoting of the Pokemon movie — Cain would be the instant frontrunner if he joined the race. According to a December Public Policy Polling poll, 68 percent of Georgia Republicans view Cain favorably, and he would begin the campaign far ahead of the field.
