Well, this is no surprise: Specter to vote for Mukasey as US attorney general. There were two ways this could play out: Specter would be a key vote and cave to White House pressure, or — what actually happened — the Democrats would cave and Specter would take the expedient route.
I suppose the only tiny silver lining in this whole sordid mess is that the GOP is so much in the tank for torture, that they haven't figured out that they are missing an opportunity: now that the Democratic party is so compromised on the torture question, it's actually open to Republicans to reformulate themselves as the anti-torture party. McCain could do it. Huckabee could do it. Even Romney could probably pull it off. (Rudy might find it tough.)
