A number of readers have flagged reports that Barack Obama actually won more delegates than Hillary (13 to 12) not withstanding the fact that Clinton won more state delegates and -- according to the exit polls -- a plurality of people who showed up to caucus. State delegates, national convention delegates, it gets kind of complicated. We're trying to see if we can confirm this. Hillary just had some brief remarks in which she seemed to concede that it wasn't clear who won more national convention delegates. We'll bring you more when we can get confirmation one way or another.

Late Update: Greg Sargent was on the Obama conference call where they made their argument.
