If you did, you might want to read Jim Geraghty's excellent posts on the debate as he liveblogged it (sorry, too many to link to, just scroll down). I felt like I actually saw it (I was writing my exegesis paper during the debate).
BTW, he now believes that it was a waste of time for the candidates to participate:
Before this debate, I was in Patrick Ruffini’s camp, in that I thought a YouTube debate was worth trying. But afterwards, I’m skeptical that this needs to turn into a new campaign tradition. The freakishly-bizarre-to-valuable-question ratio was all out of whack, much worse than the Democratic debate, I would contend.Big surprise! I never thought the debate was a good idea. I think it demeans the office of the president.
And I would have liked to see a Republican candidate rip into CNN for using a cartoon that mocked the sitting Vice President to ask a question. I don’t care if his approval rating is at 2 percent, you don’t mock the number two man in government as a power-hungry paranoid snoop at a GOP debate. You just don’t.
Update: I fixed the link.
