Alec Baldwin appeared on Late Show last night to reprise his own, sub-Tina Fey impression of Sarah Palin while recounting to Dave the (completely justifiable!) circumstances of Palin's visit to SNL. Unlike her offer to Fey that night, Palin did not serve up Bristol as a potential babysitter to Baldwin's daughter, but that's not to say these two unlikely scenemates didn't find something in common to talk about.Still, even though the two bonded while discussing Baldwin's "right-winger" brother Stephen, Alec's vote is all sewn up. And, as he says, the candidate he's pulling for is not the "guy running with Bible Spice." Still, if Bible Spice would be down for a February sweeps cameo on 30 Rock, then bygones!
