BOSTON -- Sen. Barack Obama's pick for vice president, Sen. Joe Biden, is set to address delegates at the Democratic National Convention Wednesday.

NewsCenter 5's Ed Harding reported that Biden has to follow Tuesday night's barn-burner of speech by Sen. Hillary Clinton.

Patrick Reflects On Prime Time Appearance

Massachusetts Gov. Deval Patrick was a featured speaker at the convention Tuesday night.

"I can exhale. That's nice," Patrick said after his speech. "I heard from my wife, yes. Mostly by voicemail and text messaging, and we heard from the campaign through my chief of staff."

Patrick said that he was in his comfort zone.

"I think the idea of pointing out differences in the policy choices that are offered in an Obama administration or a McCain administration is fair game," Patrick said.
