I'm thinking Mitt would already have won 6 of 7 states.
He would have outspent everyone and with his superior organization - and the inability for millionaires to bail out newt in SC, and stand behind santorum in colorado...
I think Mitt would be unscathed and riding high. IMO, the superPACs, designed to destroy obama, have really damaged that GOP brand now. Mitt is losing to obama badly among independents - a 19 point swing since november, right? bad.
