Beinart is the ultimate stopped clock. He is right every so often, and when he is, he convinces himself that the phenomenon happens far more often than twice a day. The GOP is not going to nominate Sarah Palin, whether she runs or not. At this point, Mitch Daniels or Chris Christie or even Mitt Romney would have to be seen as more electable. And since 1964, when there really wasn't anyone else, Republicans have nominated plausible candidates; in contrast, Democrats have found themselves drawn to the party edges, with McGovern in 72, Mondale in 84, Dukakis in 88, and Kerry in 04. None were remotely centrist. The GOP doesn't make that mistake. It makes others.
