Republicans imploding?

With Romney's continued revelations about his wealth and his privileged upbringing, Gingrich's wife's interview on ABC tonight, and Santorum's lack of name recognition, the republicans appear to be imploding. What is next? Maybe a draft Sarah Palin campaign?

The only bad thing for Obama is that if this keeps up, the election becomes his to lose. He's better off to keep his sort of underdog status. The republicans are making that difficult.
