Politico's Jennifer Epstein traveled with Vice President Joe Biden today. She filed a report immediately after the debate, giving the feel from inside the hall:
Though Martha Raddatz told the crowd not to applaud, there was some laughter, almost all coming in response to Biden's lines, including his mentions of "malarkey," "bunch of stuff" and, of course, "Oh now you're Jack Kennedy? This is amazing." In discussion of Syria, Biden's "you notice, he doesn't answer the question" got some nervous laughs. From Ryan, "I think the VP very well knows words sometimes don't come out of your mouth the right way," might've been the line that drew the most laughter for him.
