This is part of the house legislation in 2009 when Democrats had power in both house and senate. The Democrats immediately lost majority seats in the house in the next election before action could be taken, and a good bit of it was because of this legislation. It was noticed, and it probably won't happen again till short memories try it again. Which isn't any time soon, unless those that try, want voted out of office again. Basically no representative will want to support the plan, for fear of being voted out of office. edit: And Todd is correct, it's usually ban on sale and production. Not current possession. Unless you live in DC, Cleveland, New York City or Chicago. Where local laws already exist. (Ok, maybe some stuff in California also.) edit edit: Oh gosh, those were all blue states/areas, would you look at that...
