Great closer by Biden, using rhetorical devices to lead up to a final "Barack Obama is ready to be President of the United States". Well executed.
So, I don't think this was a KO. I think it was about a 60-40 or maybe 65-35 win for Biden, but that could have gone a LOT worse for her and I think she beat her expectations by a mile. I think he did too, and the fact that she wasn't completely embarassed might actually become the central point of this debate.
So wait, she asked right away if she could call him Joe, and then never did so once?
