Wish I had an answer for you—I don’t. Best I can do is speculate. In the past, the NRA Washington lobbyists have gained a reputation for supporting certain candidates and legislation that some (perhaps many) conservative NRA members oppose. The NRA is notorious for being narrowly focused on the Second Amendment, hunting and guns to the extent of overlooking or ignoring just about everything else. Because Norquist has a conservative reputation (or did) and has always been a strong Second Amendment advocate, I would guess that has been good enough for the NRA brass.
Thanks for your input.
I think the NRA of which I am a life-long member, should widen their scope and look at the big picture. That being a Muslim takeover of our country where nobody will have a gun except the muzzies (0bama’s brown shirts).
