You need the rednecks to rise up first. Until they realize they've been duped by their (Republican) politicians,they will lick the boots of their oppressors. Once they wise up, you'll have an armed population that isn't going to 'back the blue' anymore
As a red neck from Florida, you underestimate how far boot lickers will take things. I sometimes legitimately fear an American Reich starting in the south. My neighbors have some seriously fucked opinions.
