...the whole performance really has to be taken in context to be understood. It's a collage of elements picked up in her rise to Governor, the pregnancies, the VP run, the post-election scandals and resignation, the palm-writing incident -- and that says everything to me, that she's still flogging that hand-note schtick as though it were actually funny, as though she'd scored points somehow instead of embarassed herself and her party (R or T, whatever). That speech is the sum total of her experience, politically and personally, without editing or organization (I defy anyone to outline that monstrosity!) except that she is at the center, that she has never been wrong, and that her place in the world is in service to a greater good. Which is why she's not going away.
It's really worth reading the speech. There are a few public and academic figures I've known who seem to defy experience and get worse at public speaking as time goes on. I'm not sure how that happens, but it does.
