It was disappointing from an entertainment point of view. I expected a bloodbath, and at least half a dozen awkward moments as Sarah Palin stared open-mouthed at the moderator, trying to figure out what to say.
But Palin did far better than I or anyone else probably expected. It's hard to reconcile the Palin from last night with the one from the Gibson and Couric interviews. Maybe she's a good study, and when she prepares she does well, and maybe she just didn't prep for the interviews. Or maybe she has some sort of phobia regarding reporters that makes her brain freeze up. Anyway, she did a good job, and most Republicans will probably breathe a sigh of relief, convince themselves that the VP slot isn't that important anyway, and cast their vote. But I don't think the performance was enough to undo the damage of the last two weeks, and probably won't sway independents or undecideds in any significant way, which is what McCain really needs.
Biden was good too, but I didn't think he was nearly as sharp as he was in the primary debates, where he managed to seem honest and down-to-earth and less of a politician than the others on-stage.
