Betsy Ross: Given another article that came out today in the Observer: http://www.observer.com/2008/february-5-obama noting the paper's endorsement of Obama, I'm now wondering if there might have been an Obama mole instead.

Speculation about moles aside, the Edwards campaign mention that this was a bungled quote, with reference to a "bad game of telephone," sounds pretty convincing. Third-hand quotes are notoriously unreliable.
