The Democratic National Convention Committee has unveiled a novel theme for the Denver convention: "America's Town Hall," complete with questions from the public.

Kasnas Gov. Kathleen Sebelius announced the format on a conference call with reporters just now, along with a Web page where people can go to submit questions in writing or as video. During the convention itself, selected questions will be replayed live from the floor and then answered by a convention speaker.

The will also be a live element, said Sebelius: "There'll be an opportunity for people to actually tune in and call in and be included live as the convention is underway."

Hopefully the call-in questions will themselves be pre-taped earlier in the day, so there won't be any live questions during the convention asking about Baba-Booey's health plan.

Late Update: A Dem convention spokesperson confirms to us that all questions will be taped, with all answers delivered live.

Late Late Update: The Obama campaign clarifies to us that "America's Town Hall" is one running element of the convention, along with the themes for the individual nights: "One Nation" for the first night, "Renewing America's Promise" for the second night, "Securing America's Future" on the third, and finally "Change You Can Believe In" on the night when Obama is officially nominated.
