I had to deal with them extensively on a high profile campaign decade ago, and from everything I hear they haven't changed. Imagine a huge corporate behemoth with factions within factions always at war with one another, everyone posturing to get a leg up on the other guy. It's absolutely surreal. You'll meet a group of them at some event and one of them will slip his card in your pocket whispering, "Call me, I'll give you the straight story on all of this, my colleagues here won't always do what's best your candidate." And then another guy will wave you aside and say, "Be careful of that guy over there, he'll try to pull you in under his wing and no good will come of it..." and on and on it goes.
Gun Owners of America? "We're with you all the way man, let us know what we can do for you."
Sorry, but GOA and the others are just another faction of the pro-Second Amendment groups, who are posturing for your money. It matters little if they are inside or outside the NRA....they just want the money.
If you people can't see that, and would rather tear each other apart, then consider yourself useful tools of the left.
