Romney won HANDILY. He was smooth, articulate, knowledgable, agile, and contradicted a good many lies with ability and conviction.
Obama was blustering, lying and verbose. He worked up a forceful outrage over Libya at one point and may have dominated except for Romney's refusal to be cowed; Romney came back and very effectively challenged what he said.
Clear winner was very definitely Romney despite the chatter saying otherwise.
I think the debate had an ebb and flow to it. It was even in the beginning, His Excellency, with help from the moderator who would not let Romney counter his rebuttal lies, got a leg up in the middle and Romney won the end, especially his point by point indictment of His Excellency’s performance. Little Barry looked depressed listening to Romney school him on promises not kept, failure upon failure government. So, on balance it was a draw on TV.
So, His Excellency did not do what he had to do to turn the Romney tide. His performance may slow it, but unless Romney shows up naked on monday, he cannot lose.
