So long as I'm talking about dirty campaigning, it's been hard to figure out if the Clinton campaign was behind today's picture of Obama in a turban. But given the number of reporters trying to track the information down, my hunch is we'll know soon enough. And if it is proven to have come from the Clinton tent, that might well be the end of her campaign, as livid superdelegates abandon her, the media lashes her for the attack, and the narrative slips irretrievably from her control. Indeed, the campaign's repeated declarations that there's nothing wrong with the photo seem, to me, to be preparing for that eventuality. We'll see.
