I understand that there was a big shuffle in the GOA leadership in the last year, with Dennis Fusaro being fired for being too agressively pro-gun (ie he was taking on the NRA on some of their anti-gun legislation) so I guess what you say is likely - sad.
As for the NRA, chances are the problems you have with them don't come from Fairfax, but your state director. We have Todd Adkins in Michigan, and no such problem here.
As for GOA, they fought the bill openly, said it 'wasn't good enough', lied when they said it wasn't shall issue, called two reps who are longtime friends gun grabbers, and lied when they said they were working on the bill with then senator David Jaye. I know who his staffer was then. He never talked to them.
They also complained about shall issue being registration, but that's irrelavent since all pistols in Michigan are already registered. Personally I think GOA was whining since they are not in the loop in Michigan.
