Romney most likely never wanted to go, he was purely told to do it to stop Ron, or at least TRY to. ME is a state that if you win, ...well, you win, and that is that. Pretty much considered a state that follows what goes on elsewhere , considering the small voting bloc. Of course, a good portion of delegates to grab up, small bloc or not, but no major frontrunner would usually ever bother in the past. Romney making a mad dash up there, makes him look like a desperate fool, and also to the ones who know how 'the game' works, like a desperate fool trying to stop Ron Paul.
That is probably the likely outcome, but id rather the votes go to Rick or Newt, as they too far behind to make a dent to catch Ron.
