I wouldn't be so sure about this. We know Romney isn't. He is running as the "centrist" who is "nuanced" on the social issues. I'm sure Cain would want her support but he's just trying to win the nomination. I don't know if Perry is pushing for it. He's campaigning against obama.
The problem with Palin is her detractors are as intense in their dislike of her as her supporters are in their liking her. If we are going to win in the general election we need the swing votes. The swing votes we need to pick up are the middle class suburban women and the RC's.
Actually the problem with Palin is she just punked all of her OWN SUPPORTERS.
