As much as I hate her demeanor, speaking voice, approach to media relations, face, etc., Palin is an admirable woman who takes big chances. Democrats and Republicans alike are wasteful big-government types now, and we have many of the same people who support a smaller government turning up their nose at Sarah Palin when she's actually exactly what they need. If you have the kind of media exposure that she does, you don't make the decision to align yourself with a tax-revolt movement lightly.
If her presence results in the party moving away from the neocon side and towards a smaller, Goldwater Republican party, I'm comfortable with that. Unfortunately, I'm afraid she herself is too polarizing to be effective in that capacity, and so her admirable message is going to be buried.
