Well, to start with, the Christian Right, believe it or not. She prefers the libertarian Pro-life view- Overturning RvW and returning Life to the states. That is out of step with the Pro-Life community, even if it is acceptable to NRL. Her stated position and actions also make her a mild advocate to possible opponent of the Marriage Amendment. That this is purported to be her stronghold makes her less desirable.
As far as fiscal Conservatives go, what little record she has shows more spending when she left than when she arrived. She is good at slashing budgets, but she also likes spending money on big projects.
As to Defense and Foreign Policy, it is her weak suite anyway. Any credibility in this area is going to be a reliance on others, IMHO. That isn't to say it can't be overcome, but military folks would rather have someone with military experience, and would be more likely to back a warhorse in the primaries.
Stack her up against the real thing, Duncan Hunter, or one of his caliber, for instance, and she starts looking mighty pale. She is a populist without enough record to tell what she is for sure in any direction. That she came out *for* the bailout, and *for* some sort of amnesty will hurt her immensely.
Do you have a source for the “libertarian” views? Something ironclad? I have a lot of folks on another board who accuse her of being “fundie”....I’d love to be able to cite facts to the contrary.
