B&C’s Marisa Guthrie talked with execs from Fox News and CNN about the latest twist in Campaign ’08: that the first presidential debate might be delayed. “The only thing that is expected in this presidential election is the unexpected,” said CNN political director Sam Feist.

Guthrie writes that due to the planning and security that goes in to these debates, it will not be easy to reschedule.

Says Fox News VP Jay Wallace, “There is a limited window of opportunity. Security at these things is months in the planning. And the networks are not going to want to give up real estate. It’s crunch time with the fall shows coming on and the baseball playoffs. The networks are there to make money. They’re already challenged by the sagging economy. The window is Friday night.”
