Obama wants the debate to go on, he announced at an afternoon press briefing. McCain announced earlier today he would like the debate to be postponed.

"It's my belief that this is exactly the time the American people need to hear from the person who in approximately 40 days will be responsible for dealing with this mess," Obama said. "And I think that it is going to be part of the president's job to deal with more than one thing at once. I think there's no reason why we can't be constructive in helping to solve this problem and also tell the American people what we believe and where we stand and where we want to take the country. So in my mind actually, it's more important than ever that we present ourselves to the American people and try to describe where we want to take the country and where we want to take the economy, as well as dealing with some of the issues of foreign policy that were initially the subject of the debate."

For what it's worth, the University of Mississippi is moving forward with the debate as planned. A press release from the university's chancellor:

The University of Mississippi is going forward with the preparation for the debate. We are ready to host the debate, and we expect the debate to occur as planned.

At present, the University has received no notification of any change in the timing or venue of the debate.

We have been notified by the Commission on Presidential Debates that we are proceeding as scheduled.

We will keep you posted as information becomes available.
