I didn’t watch either the Presidential or Vice-Presidential debates, but Megan McArdle seems to have the most even-handed analysis of the Veep sock-fest:
Biden launched into the eye rolling and the smirking, the head shaking and the laughing, and of course, the constant interrupting, nearly as soon as Ryan started talking. I assume that means it was part of their debate coaching. I mean, I don’t think that he intended to come off as an obnoxious eighth grader heckling a classmate, or to actually shout himself hoarse with his constant interruptions. I’d guess they told him to come across as genially disappointed, more-in-sorrow-than-in-anger, and he kind of went off the rails.
Both candidates looked far overcoached for this debate; you could hear the hesitations as they desperately tried to overstuff their responses with canned lines. And that overcoaching showed up in their demeanor. Paul Ryan was speaking so slowly that it sometimes sounded as if he was reading off a teleprompter set at half speed; this made him seem uncertain of his memorized answers, not deliberate. And Biden — well, we seemed to be watching him going through a second puberty, complete with voice changes.
Yet I suspect that MSNBC was right: this was what the Democratic base wanted to see. Yes, they also wanted to hear him defend their issues. But they already agree with him on the issues. Their biggest desire was just for someone to express their disdain for the Republican Party, and particularly its rising young star — to display their collective contempt in a public venue. I’m not sure exactly why this is so important, but I seem to recall that the same dynamic from Republicans in 2004. There’s a lesson there about where American politics is headed, and it’s a pretty grim one.

But unfortunately I thought Biden threw that away that lead with his behavior. It’s hard to get enthusiastic about a candidate who apparently might go full frontal jackass at any moment. I’ve seen a bunch of progressives dismiss this as conservative carping, but watching CNN’s ticker of undecided voter sentiment, it seemed to me that every time Joe Biden started talking over Paul Ryan, Ryan’s ratings went up. And it was the first thing that the CNN hosts, most of whom I guarantee are not Romney/Ryan voters, commented on. The panels of undecided voters also brought it up — and none of them said, “It made Vice President Biden seem really authoritative and in control”. Some of the commentary this morning seemed so suggest that if progressives just insist sufficiently loudly that it was awesome, everyone else will have to agree. I think this rather overestimates both the ability to “work the refs” in the media, and also, the power of doing so.
