As I'm a life member of NRA, I didn't drop my membership (like some former president/father of the president...) but I don't send 'em any more money, either. Every year I vote for the board, but I almost never vote for a politician, musician, actor, former pro basketball player, etc. I try to pick people that will really support the 2nd Amendment.
Oh, and I'm also a GOA life member and TSRA endowment member.
