Politico - Gun Control doesn't survive Christmas
Unfortunately, two bills are still going to be introduced tomorrow. A new AWB in the Senate and a high capacity magazine ban in Congress. Doesn't mean either will even be allowed to go to the floor for a vote but if nothing else the linked article does show that the time to capitalize on the crisis has passed.
Speaking anecdotally, a lot of friends and neighbors simply didn't think what they heard about the new AWB would have done squat to prevent Sandy Hook. Even though they don't follow the issues as closely as I do.
I expect most politicians to treat these bills as poison, but I will be paying special attention to any Republicans that try and jump ship over the next couple of months, assuming the bills aren't DOA on Jan 3rd.
