I do believe that Conservatives will unite behind the ultimate candidate. I don't think so if it's Romney, however.
Right now I think we are all trying to get our candidate of choice elected and I know that I can be quite adamant about my wanting Herman Cain.
I would have a really hard time with Romney - been there done that in ‘08.
I don’t see why saying Romney didn’t have a heart would disqualify a candidate for President. We say a lot worse about Obama all the time.
And I have a feeling the general electorate aren’t all whiny sissies who are so easily offended by political rhetoric. Usually it’s just liberals that play the overly-sensitive “you hurt my feelings” game. I’ve never seen so many conservatives with such easily bruised psyche’s.
