The NRA doesn't usually endorse anyone in the Primaries. Given the likely DemonRat nominee, they are quite likely to endorse whichever candidate, Conservative or RINO, that is nominated by the Republicans. Although they didn't endorse G HW Bush in his re-election bid, and we ended up with Slick Willy and the Assault Weapons ban.
The NRA did endorse RINO Charlie Crist before the primaries.
IIRC GHWB, NWO puke, publicly renounced his life membership in the NRA after the totally accurate jack-booted thugs remark (I think made by Wayne LaPierre). GHWB also calls Slick Willy "son".
I won't attempt to link the NWO statements of GHWB, his familial love for the Scumbag, and his public dumping of NRA because that would invite a foil award.
I hate the occasional weakness of the NRA, but I do believe that without them we would have already lost our guns long ago. I also believe in belonging to more than one gun rights group. JPFO has personal knowledge of where gun control leads.
