Mitt is the big LOSER of the night. There's no other way to spin it.
This is a guy who thought he could completely SKIP Iowa and skate his way to the coronation nomination. He was FORCED into Iowa by GOP enthusiasm for Newt (short lived as it was). That we "won" there means little considering he wasn't planning to even have to be bothered with the place.
This is a guy who spent 5 million of his own campaign funds and 20 million in SuperPac funds to obliterate Newt. It worked. Well, sort of. Except when it didn't. Now he's got a new, vengeful enemy who knows how to play politics and has lost the news cycle because Santorum's "come-from-behind" (sorry) story, which the media will LOVE and GUSH (sorry) about all the way to NH.
