My understanding is that the NRA’s exemption alone would mean most Democrats would not vote for the bill at all. That’s a slick political move on the part of the NRA. It stopped a bad bill for everyone. I’ll keep my membership in the NRA.
How about “Keep the powder dry, and wait for this to shake out”?
If they were indeed that clever then they have my backing. But I note that at least one member of the board of directors published a column criticizing the move.
