Politico has this report on Palin's strategy tonight:
Sarah Palin plans to go on the attack in tonight’s debate, hitting Joe Biden for what she will call his foreign policy blunders and penchant for adopting liberal positions on taxes and other issues, according to campaign officials involved in prepping her for tonight’s showdown.
The Palin camp is projecting surprising self-confidence in the pre-debate hours, despite the vice presidential nominee’s uneven — and, at some points, peculiar — performances in recent television interviews, the officials say. Top advisers to John McCain privately say Palin’s recent CBS interview was a borderline disaster, especially since it played out in several segments over several days. Tonight will be different, they say.
“This is going to finally put her back into a position where we see her like we saw her the first couple weeks,” a McCain official said. “She was herself. She was authentic, and people related to that. ... Tonight, she’ll get into a rhythm. You’re going to see her in a way that you haven’t seen her yet.”
