My guess is the call went something like this:
President Bush: Hello Senator Obama, this is the President.
The One: Wassup whitey?
President Bush: Just to let you know, I'm addressing the American people this evening. I have two versions of my speech, one in which I say you are missing in action during a time of crisis, while John McCain put his country first, and another in which I thank both candidates for coming back to Washington. You can pick which one I say.
The One: Whatchoo talkin' bout Willis?
President Bush: Good day, Barry.
Bush gave a good speech. He was absolutely right and explained the situation properly.
If they are smart, they will hold this at Blair House.
