They won't have to change the constitution. They'll use other things such as outrageous taxes on firearms, ammunition, and hunting equipment. Impossible laws for firearms and ammo manufacturers to follow and make a profit. If you don't believe this , then do some research because they have already tried all these things. And remember that if Obama gets a second term he won't have to worry about getting reelected so he won't care who he screws. Last but not least the next president will likely appoint a couple supreme court justices.....if that doesn't scare the hell out of you , considering who he has already put in there, you better wake up!! Oh sorry, I forgot Obama's buddies at the UN!!!!! Damn....now I'm depressed!
