I suspect you are correct. Gun control is not a viable issue for the Dems to take up. I suspect Obama can't win unless a similar phenomenon to the last election occurs. As Glen Beck says, "I'd vote for my shoe before I'd vote for Obama."
My representive cast the final vote for the AWB. I have never forgotten that betrayal. Unfortunately he lives in luxury on his Congressional retirement. He started out as a bus boy at a local restaurant. The American dream story, but he blew it!
