I never thought I would identify with a member of Obama's crack communications team. But:
... less than seventy-two hours before the speech would be delivered to a live audience, Favreau was sitting alone in an unfurnished group house in Chicago when the boss called. “I’m going to give you some stream of consciousness,” Obama told him. Then he spoke for about forty-five minutes, laying out his speech’s argumentative construction. Favreau thanked him, hung up, considered the enormity of the task and the looming deadline, and then decided he was “too freaked out by the whole thing” to write and went out with friends instead.
Favreau is Jon Favreau (not the Hollywood guy, a speechwriter) and the speech in question was the big one, Obama's response to the flap over Jeremiah Wright and "God damn America!" It got written in the end, which I hope is a portent. The article is by Robert Draper in GQ, via Sullivan, of course.
