Your faith in the NRA and Trump is mind-numbing. That's some impressive mental gymnastics there.
Tell me though, what was the last piece of democrat passed anti-gun legislation passed that still affects you today? Gun control act of 1968?
Bump stock ban... Republican
7N6 Import ban ... Democrat
AWB (No longer law) ... Democrat
922(r) ... Republican
Machine Gun Ban .... Republican
etc etc etc
No 'faith' required, you just have to be realistic about the politics behind these things. Things happen for reasons, and to say that there isn't an ongoing quid-pro-quo in DC is pretty naive.
I find a lot of folks 'faith' in their elected Congress-critters being willing to protect their rights under the kind of popular and media pressure that was being put on them after Vegas to DO SOMETHING NOW also pretty naive.
Maybe a few would have stood up after Vegas but most would have gladly hopped on any bill that would get the media and the public off their backs.
And BTW, all the gun control you lay at the feet of Republicans, with the exception of the Hughes Amendment, was done via executive order.
Only the AWB was a truly separate bill (Hughes was tacked on to FOPA, a GOP pro-gun bill) and that was 100% driven by Democrats, although plenty of RINOs went along with it.
And since it's become so popular to bash the NRA, don't forget who forced the sunset provision into the AWB, something unique to that one law as far as I'm aware.
Just because WLP has turned the group into a quagmire doesn't take away from the things they got done in the past.
