Long ago, back in '68, -- the NRA supported a gun control act that in effect gave away the farm. -- The NRA helped establish the 'principle' that Congress has the power to infringe on our rights to keep and bear arms thru 'regulations' on commerce.
The NRA is indeed "in the cesspool of Washington politics". -- Watch them like a hawk, and keep them lean & hungry.
Can you tell us, friend, what the "fallback" position being offered by the other side was in the wake of a series of high-profile assasinations culmanating in the killing of Bobby Kennedy? Can you list for us the interest groups which were marshalled in support of GCA '68? Can you tell us what the media was doing to the pro-gun position back then?
