I know very little about these orgs. If we can't get them together, can't we just lobby them to establish constructive ties and promote common issues and recruit their members to legislative issues?
We have more than one guns rights organization in the USA, by the way, and not everybody likes or supports the NRA (which is a mistake nowadays IMO). We have several large ones.
Gun Owners of America has billed itself as the "take no crap" alternative to the NRA, although the NRA has come around in recent decades and been stronger on policy. GOA does more at the state level than NRA.
You know all those NRA victories you have read about in courts and the US Supreme Court in the last 10 years? Yeah, that' wasn't the NRA. That was the Second Amendment Foundation. The NRA was tangentially involved in a few, but did not champion any of them.
Here in The Great Commonwealth of Pennsylvania, we have FOAC. They have done more to improve gun laws in our Commonwealth than all national gun organizations combined. FOAC also sends questionnaires to politicians, tracks their voting records, and provides a voting guide that goes all the way down to your local county clerk. I print out the guide from my district as a starting point and then mark it up as I have time to investigate some of the candidates. I then bring it with me to vote. Good idea, right? It makes the legislators nervous when they receive that survey in the mail.
And there are dozens more worthy of recognition. And, yes, they do butt heads and compete from time to time, but they do work together from time to time as well.
Here is an interesting idea:http://amgoa.org/This is an organization my friend started. They don't do any lobbying. They don't do any direct organizing. They are a clearinghouse for information to members of all gun organizations and a conduit for collaboration. Maybe you need a similar outside the box idea, an impartial coordinator between all the groups. This one is run by two people with about 3 or 4 other part time contributors.
