I’ve thought about this question myself: does Palin’s VP candidacy change Hillary’s calculus for 2012?
I think it does. As Ms. Althouse says, it presents her with a conundrum: whose election would be best for Hillary? The way this campain is shaping up—Obama’s Biden move and McCain’s Palin countermove, and all those ads and answering ads—makes me think of it as a particularly knotty game of chess.
And there are more than two players in this game. There are at least three, and Hillary is most definitely one of them.
