On the offense

I think A. Serwer writing at Tapped correctly predicts what the debate will be like:

Sarah Palin has been at her most effective delivering scripted attack lines, and the debate won't be an interview. She won't be answering tough questions as much as she will be re-heating the slams against Obama she's spent time memorizing all week. All indications are that Palin is actually very good at "the nonanswer." Whether she comes across as knowledgable doesn't matter if she manages to reopen doubts about Obama's ability to be president. Expect her to turn questions about her qualifications into questions about Obama's, and inquiries about her religion into arguments about Rev. Jeremiah Wright. All she has to do to reignite that conversation is frame herself as a victim of a double-standard -- and that's the other thing she seems to be great at. The media will do the rest.
