Add my name to that list. If not for Sarah Palin, I would have voted for the Libertarian candidate. I have maintained all along that SP is the ONLY reason McCain didn’t come in third.
As for her endorsement of McCain for his last bid for reelection, I think she recognizes that, unlike democrats, we’re smart enough to see that for the political payback it was.
Moreover, McCain's 2008 campaign manager and GOP strategist Steve Schmidt felt or showed no such loyalty to Palin when we know it was she who brought in the conservative vote in 2008.
