I believe she was waiting to see if a candidate other than Romney or Perry would move forward. I think if Cain hadn’t surged, she would have run.
I think she (rightly) believes she can do more good doing what she is doing and she will try to ensure Romney and other RINOs will not be our candidate.
If Romney were to get elected, she knows exactly where to apply pressure. If she were to run she would be pressured to be “attractive” to moderate voters. I don’t think she wanted to fight that battle and I don’t think that is her mission.
Her mission is to effect change in the way our government works, no compromise. If she were on the inside, who, with her influence, could keep up that kind of pressure on the outside without fear of reprisals from the press and the electorate? No one.
What is the half-life of a 1/2 term governor and VP candidate on a losing ticket? Five years? Perhaps six and after that, pffft.
