Its only speculation on my part, but...

The bulk of the Tea Party GOP can't stand this guy. Look at the tepid endorsements he's been getting from Republican celebrities and the conservative press. Right now, leading GOP personalities are joining the chorus demanding that he open up his tax records. More than anyone else, they know how politically destructive they could be, even if there is no evidence of illegality. Most of the slams being thrown at him (remember "vulture capitalism"?) were not originated by the Obama campaign, many came from Romney's own primary opponents. And he didn't make any friends on the far Right when he crushed their candidates with slick PR carpet bombing funded by an unlimited warchest from the RINO wing of the Daddy Warbucks, Country Club GOP elite.. And of course, he continues to flip-flop and etch-a-sketch (again, TP rhetoric, not Obama's) in an era of YouTube and video tape.

This may give the Righties just what they need to mount an anti-Romney floor fight at the convention. A challenge to his candidacy may emerge, perhaps led by Ron Paul and his minions. They are clearly organizing to do something mischievous in Tampa next month.

Stay nude for the tunes.
