Biden delivered the kind of performance that thrilled Democrats—and enraged Republicans, who were torn between blaming Martha Raddatz and the expressions on Joe Biden's face. But as amusing as the GOP's spin may be, it doesn't matter. Democrats needed a strong performance from Joe Biden, and they got it.
And among the voters who count—uncommitted and undecided voters—Biden won, both in a CBS snap poll of uncommitted voters who watched the debate and in an NBC focus group of undecided voters in Virginia. So last night was a good night. Democrats got what they wanted and Republicans didn't.
