Ed Kilgore says to think twice about Palin's chances:
This base of support for Palin maybe not that large, but very passionate, and very powerful in places like the Iowa Republican Caucuses isn’t going to abandon her just because the Serious People in the GOP laugh her off in favor of blow-dried flip-flopping pols like Mitt Romney or blandly “electable” figures like Tim Pawlenty. To her supporters, mockery is like nectar.
I don't disagree. But that is the reason why she is so dangerous to the Republican party. She is a kind of poison pill. If she becomes the leader of the national GOP, the wilderness they are now in will seem like an oasis.
