I've finally got around to watching the debate and, for me, I thought Palin was a bit rubbish as a debater. While Biden seemed good at putting out answers, statements, counterstatements, and stats in answer to questions put to him, Palin didn't seem to want to engage with any of the questions and, more often than not, tried to drag the debate off into zones it need not. No doubt this is what happens when you've got five weeks to cram while your opposite number has years of experience in office and has a better handle on what he's talking about. For Palin, it seemed like she'd been told to ignore the questions, use your 'hockey mom' schtick when in doubt as personality will win through in winning votes rather than actual policy, little of which she seemed capable of discussing.
For me, if there were to be a winner, Biden by a long margin. She can say darnit! and doggone! all she likes, she had little of substance to say.
