I just saw Obama's press conference.

He called McCain this morning re the economic crisis, then later heard back this afternoon that they want to cancel the Friday debate. Obama said that presidents need to be able to deal with more than one thing at a time, and there is no reason to cancel - that now more than ever, the voters want to hear from the candidates where they stand and what they would do. So... at this point, Obama is ready for the debate, McCain wants a time out.
