I think something is going wrong for her. I watched a bit more of these interview clips on various news channels, and it seems like she has lost her confidence. She gets kind of stammery and flumoxed. My very first impression of her was that she could speak well, even if I didn't agree with anything she said and I thought her beliefs were wacko. She still seemed to be able to deliver her remarks.

I think after the Gibson interview and the "Bush Doctrine" flub, the campaign pulled her out of the game too long, and she lost her nerve.
