Palin...

Initial reactions:

She's okay with a speech when she knows what she's talking about. The folksy bits are key for her. But look at where she's talking about foreign policy: she stumbles, she falters. Biden will eat her alive, for sure, but the key is making sure he's not mean about it.

She's good with the snippy comment. She's good with the sly joke. Good delivery on turns of phrase. Not quite as good at moving into her applause lines, but she'll get better as she goes along.

More thoughts soonish.
