I definitely see them as mostly Republican/Conservatives, but because of them even democrats can always legally obtain guns. The USGov can never remove the right to bare arms, or the pro-gun people will flip out. So a semi-unknown number of guns remain in the public's possession preventing the USGov from ever trying to really take over. Best chance is for USGov to slowly erode privacy/rights as they're doing, but I think the NSA leaks have messed that up and put all kinds of people, even republicans, on guard. If a civil war actually happened, I think the pro-gun people are a wildcard that the USGov cannot depend on. I think they'll actually split up and a significant amount of them would side with democrats because of their desire to "protect the nation & what the USA flag stands for". With the NSA leaks, I think a lot of them feel like they've been fooled and are now just "pretending" to be republicans, but deep down inside they wouldn't defend the USGov in a civil war. I also think there are a bunch of military personnel who are "just following orders" for now but would defect in the event of a civil war too. Someone(s) just has to be the martyr to get the ball rolling.
