Chaotic Week In GOP Campaign, Cain Tops Polls

Businessman Herman Cain is running neck in neck with former Massachusetts governor Mitt Romney in the GOP Presidential race according to a Washington Post/ABC News poll. An overwhelming number of Republicans say reports that Cain may have sexually harassed two women employees "do not matter" when it comes to picking a candidate.

Cain's campaign has rebutted the allegations and accused Texas governor Rick Perry's campaign of spreading the story. Perry denies that allegation, but he's been on the defensive for an entirely different reason, after video clips of a speech he gave in New Hampshire led some political observers to wonder if the governor may have been on pain medication.

And, where has Mitt Romney gone? We take a look at the week in Republican Presidential politics.
