Obama can do nothing more than to push gun owners underground, making them feel and behave like criminals, while they are doing no wrong. He really doesn't comprehend the massive anger that would result if he gets his way on gun laws. He thinks gun owners, especially those who aren't just hunting or target shooting, are a fringe minority who can be safely ignored.
I think you should send Obama a signed copy of EF&D, although it would probably precipitate a visit from the men in black.
