Obama and Blagojevich: What They Aren't Saying

I have heard from several news outlets that Obama was not involved and knew nothing of Blagojevich trying to sell the Senate seat. At the same time, they are quoting Blagojevich about Obama not playing ball. How could he not play ball and not know anything at the same time? Surely someone in the Obama camp – if not Obama himself – must have rebuked Blagojevich, creating his frustration, and therefore someone ought to have known something.
