As an aside, the "Overton Window" is a political theory which explains how an unpopular measure can be voted into law.
http://en.wikipedia.org/wiki/Overton_windowThe idea is to push something so radical that most voters would reject it, like confiscation. But, then, as a "concession" push only banning high capacity magazines. The thoughtless voter, thinking they have dodged a bullet, and to appear "reasonable" as well, agree to the hcm ban. Three steps forward, one backward, and the 2A is slowly squeezed to death. The solution, of course, is to NOT TOLERATE even the slightest infringement.
