When the NRA called for its own bill to die, 60 Senators flipped their vote. What would have happened if the NRA had done nothing.
And why do you suppose the NRA did that? Because The leadership is so principled and stalwart? They did it because other gun organizations, and some of the hardline members made it clear that what was happening was counter-productive. Then the membership turned around and pressured the leadership into killing their own bill.
Look, when it comes to sponsoring Hunter's Ed, shooting competitions, and firearms education, the NRA is unrivaled in its ability to do those things. Those are the reasons that I remain a member. But when it comes to Political lobbying and legislation, they're not nearly as committed to the 2A as they would like us to believe.
Here in Oregon, The Oregon Firearms Federation has done a better job, and made more inroads and held more gun control at bay through Grass Roots efforts than the NRA ever thought about. OFF has taken up battles that the NRA abandoned as hopeless, and won. OFF isn't, by any means, a large organization, but they get the word out, and they do not compromise. The guy that runs it, Kevin Starrett, is a warrior foir the Second Amendment, and has proven to me that the only things that Politicians understand is Fear and Pain: The Fear of losing an election, and the pain of having to live under the laws that THEY made. In that vein, he makes allies, not friends. Alliances shift, friends demand uncompromising loyalty. Those politicians that stand up for liberty get the support of OFF. Those that refuse to do so get OFF-ed
The real power lies in the hands of the average gun owner, not in some office building in Virginia or in the halls of Congress.
