Palin wouldn't have enough experience in 2012 either, not enough to counteract her being so completely crap at any question except about energy. The RNC could doll her up and throw her out there again in four years, but it would be a dumb move on their part. It would make more sense, if she is the great white hope, to use her in the same situation we have here, instead of trying to throw out an already strong sitting President running for reelection (if, hopefully, Obama is sitting strong).
It took the strongest Democrat that we'd seen in thirty years to knock Bush out of office after only one term. You have to admit that Clinton was about as slick as you can get when it comes to running a race.
