At about the 11:30 mark Obama says, "In the next hundred days, I will meet with a leader who rules over millions, with an iron fist. Who owns the airwaves and uses his power to crush all who would challenge his authority at the ballot box. It’s good to see you, Mayor Bloomberg."
The camera cuts away to a shot of Bloomberg laughing, Diana Taylor applauding, and reporter Al Hunt looking amused.
Also in New York politics, during Wanda Sykes’ speech, the camera cuts away for a shot of Anthony Weiner (in glasses!) at about the 4:50 mark.
He is, along with the rest of the room, laughing at a joke about Joe Biden's inability to keep his mouth shut.
