I doubt it will pass. The benefit, though, is that it is bringing the government hoarding of ammo into the mainstream media and public discussion. Right now, the mainstream media is ignoring this story and public discussions are limited to folks like us who watch this stuff.
I have to wonder how effective the government's actions are. I, like many others, have more ammo (and more guns) than ever before. This stuff may not be on the shelves, but it is in the hands of the People!
