How Biden screwed up:

Vice president Biden did precisely what he should not have done: Open up more questions and create more problems for the president. The next debate will consist in large part of President Obama debating his vice president on everything from taxes to Libya. Obama is once again on defense with 3½ weeks to go in the race.

He might have energized his incivil base with his rudeness and antics, but he planted a couple IEDs for the campaign that are likely to blow up.

And here’s what Ryan should have said:

I think Ryan was right not to let Biden bait him into losing his cool. Ryan certainly came across as the more appealing, serious, and decent politician. But he would have done himself and his ticket a great service if he had simply turned to Biden and said something like, “Mr. Vice President these are serious issues and serious disagreements about the future of our country. I don’t find them funny and, frankly, I find your behavior here tonight beneath the dignity of your office.” It would have gelded Biden, elicited spontaneous applause in the audience, and endured as the most memorable soundbite of the whole debate. And, it would have been true.

Yes, it was a missed opportunity.

Why Dems loved Biden’s boorish behavior:

The problem here is not just that presidents and would-be commanders-in-chief must appear presidential. It is that the liberal base of the president’s party is so filled with anger and contempt for Republicans that they can’t abide even a show of civility from their champions.

Yes, and when they mewl and whine about “incivility” from the right, like most of their complaints (racism, hate mongering, lying), it’s pure projection.

Biden was a jerk in the debate.
