I started purchasing some time ago; when it looked like the Hildebeast or the Obamanation could actually win. Never went by a sporting goods store without buying a few components.
I think that fear is moving a lot of the product, but I have to wonder about the current administration causing shortages (aside from the fear factor). I cannot believe the DOD's short lived decision to shred military .223 and .308 brass did not have its source in the White House or that line of thinking. Is the current admin stopping the importation of foreign made ammo? The only current .223 that I have found is US made. And there is certainly a move afoot to stop importing certain foreign made firearms.
Obama's back ground from the time he graduated law school has been staunchly anti-gun. Despite his convenient campaign rhetoric, I have every confidence that he will sell the 2nd Amendment short any chance he gets. He will not spend the political capital to do it directly, but there is a lot he can do that behind the scenes.
