Debate prep

All these debates remind me that the first Keyes/Obama debate is to be held on Tuesday (on the radio). And I have to wonder, how does Obama prep? Do they bring in the preacher from outside Old Navy on State Street to play the role of Keyes? And I wonder if Keyes even thinks he needs to prep. I would think it takes work to turn every conversation around to abortion, but Keyes seems to have that down pretty well.
