I have been saying the exact same thing for a long time now. It's not just AZ that has had success this way, Georgia Carry & Buckeye Firearms have both had a lot of success at the state level, and politicians in those states now seem to fear them more than the NRA.
We are diluting ourselves with MCRGO, MOC, & MGO. Not only would one large org have more members, it would have more resources to support lawsuits(like GC and BF do), and it would hold much more clout with state lawmakers. As it stands, who is really holding MI politicians responsible when they don't do what they say? With a large group that has thousands of members they can put a lot more heat on someone.
Buckeye Firearms helped get a lot of people elected in the last couple elections, and they have seen some very good gun laws passed as a result, because the politicians in OH fear them. They also had the funds to take the City of Cleveland all the way to the OH supreme court to fight Clevelands attack on preemption.
The day that this state puts together a very large, well funded state organization is the day things will start to get done here. Until then I think we will continue to see what we have seen the last 2 years, people who make promises to get elected then do nothing because they know no one is large & powerful enough to make them keep that promise.
ETA- this is not meant to be a knock on any of these groups, i think all have done good things and i think all try to get things done(well at least MOC and MGO do)
