The excitable MSNBC anchor Chris Matthews, who after the first debate railed on air about the president --"I don't know what he was doing out there. He had his head down, he was enduring the debate rather than fighting it!" -- declared Biden Thursday night's "clear winner."
And then there was the laughing.
Where Obama had come across, even in the most optimistic assessment, as reserved and disciplined in his delivery, Biden was just as apparently having a good time taking on his young, Republican challenger. Biden, 69, and Ryan, 42, were colleagues in Congress for a decade before Biden joined the Obama team in 2008. Their exchanges were often pointed, but never mean-spirited. And Democrats were laughing right along with their man.
On Twitter, 6 percent of the tweets being sent out at 9:45 p.m. ET -- and 500,000 total by night's end according to Yahoo's "Signal" -- mentioned Biden's chuckling. One opportunistic user created a @LaughinJoeBiden account, which had more than 9,000 followers by 10:30 a.m. today.
