Part I: Palin did not answer questions directly.
Part II: Biden incredibly strong--pointed out Palin "I heard no plan" on Iraq, very strong on economic and FP issues.
Veep issue devastating for Palin--actually claimed broader powers for VP, clearly without knowing actual constitutional powers. Biden powerful on Cheney--dials way up.
And then...The turning point. The Biden tears. After that, Biden was most clear, passionate and strong, and from there, Palin was gibberish.
Biden win.
Update:
