Wish I'd seen what you wrote before you deleted it.
Coming back to the OP, what I'd like here is an update. Apparently this is old news. But presumably, there was some kind of fallout from this incident - journalists getting stuck into him for his inconsistency, interviewers pushing for a response, fellow "liberals" (I don't even know if he actually counts himself as one; 63% of Democrats
don't count themselves liberal) criticizing him for having a gun, etc.
I am aware of the considerable mileage that various conservative commentators have gotten out of this on the web. What I'm really interested in though is whether this has changed the debate in any way. Has anyone actually succeeded in drawing him on this?
