Their leadership is the definition of corruption. Wayne LaPierre and his lieutenants are grifters and need to be run out of town on a rail.
Back in the day they promoted firearm education and responsible ownership. Its very disingenuous for leftist idiots to imply any large majority of educated firearm owners not promoting responsible ownership. But they do.
The NRA used to not care if you voted Democrat or Republican, they just promoted firearm education. In fact look at Texas, back in the LBJ days it was solid blue... and heavily entrenched in firearm ownership.
In the modern era that ideology has been assigned to the right predominantly and you see that in the NRAs messaging. Their far right messaging is solely to extort their base for more funds to fight off the progressive boogeyman. And it’s effective messaging.
Honestly I don’t see 2a support being Democrat or Republican. It’s one of those fundamental Libertarian points. I’m granted ownership rights in the Constitution and the government needs to leave those rights alone. It’s become a Republican issue if for no other reason than a counter to the far left firearm confiscation narrative, it’s just reactionary. Thus the NRA feeds that far right ideology as there are far more Republicans to extort than their are self acknowledged Libertarians. Just my humble opinion.
