Whenever That UPS guy pulls in the driveway, my wife says: there you go, helping the economy again.
I see buying extra ammo the same way. No harm in getting an extra box from the local sporting goods store every now and again.
I've voted both parties over the years (try and do my homework to avoid the idiots) and don't give a hoot about any of them on a personal level because they certainly don't know who I am.

That being said, I like to enjoy my life and not get stressed over politics.
If it's a sunny Sunday afternoon and I can take an old friend shootin', my day just got better. I can't blame anyone for buying up extra ammo.

Just remember... As long as "goods" are taxable, the government isn't going to get rid of it(them) any time soon.
Just have fun shootin"!
