Grasping Reality with Both Hands: Brad DeLong's Semi-Daily Journal: Bacon sounds like a complete idiot. But Matt compunds the error by assuming that the Obama lie is being perpetrated by right-wingers. There is zero evidence to support this.

I would say that it's more likely, not much more likely. I do suspect that Perry Bacon and his bosses are doing a favor for somebody. It is not clear for whom.
