I went to two DNCs, in 2004 and 2008.

Both times I heard what the cable news networks were reporting, scandals and controversies, but didn't see any of it on the floor. 

I think some people perform for the cameras, and say things that'll get them more coverage. I saw almost no dissent either time, though the media were making the most of divisions.

I try to remember that as I see them trying to make it sound like the Dems are in trouble. It probably isn't very real.
