I need help understanding why Romney wouldn't carry Mass.?
He's done it already, and to my knowledge is well regarded there.
Romney very well might carry Mass. He might also lose it. It's not a done deal either way. However, he would certainly put all of New England in play, which is something the dims can't survive given a good and relatively conservative Repulican candidate.
All of the red states would almost certainly go with him and the dims would have to fight tooth and nail to keep the blue states blue. Can you say "wipe out?"
