Joe Biden...

Each time Joe Biden's picture was shown on the big LCD screens, he always seemed to get the biggest applause.

This morning we were told that if you lose your credentials, you can't get them replaced. The plastic attachment to the metal clip is easy to tear, so I wonder who did the stress testing with these things. Earlier in this morning they also said not to laminate these things, and it turns out there's some radio tag embedded in the credential that they check.

We spotted Bill Maher walking through the floor....Anderson Cooper, Wolf Blitzer, Donna Brazille, and James Carville are just sitting in the CNN studio on the convention floor. Not sure exactly if they're really paying attention....

We're being passed around different rally signs: first was Change We Can Believe In, second was Kennedy, third s One Nation. What's next?
