It was a poltical dramatic ploy that didn't work. McCains campaign is built on cheap gimmicks, we saw it with his choice of VP and this latest backfired stunt.
As Obama said,
*"I've been able to stay entirely on top of negotiations" through phone, e-mail and staff communications, Obama said. "We can do more than one thing at a time; that's part of what's required if you want to be president of the United States." *
It looks like McCain got the message and will follow Obama's lead and in fact be at the debate tonight.
