The Obama campaign has released the ad below on firearms.
When it scrolls by, it is worth noting the mention of "Vote 202, S Amdt 4615 Adopted 84-16." This is a vote Obama supported preventing the confiscation of firearms during emergencies. (I should note a similar bill passed almost unanimously in the Oregon legislature.)
Anyone who scrolls through this blog will know I've come lately to the Obama camp. I have questioned his views on RKBA. But what I am seeing is an evolving understanding from an open-minded politician about issues his initial constituents in Chicago and Illinois were not well informed about. As he has become a national leader, he has realized he has a national constituency. This constituency is damn serious about its 2nd Amendment rights, and I believe Obama understands that.
