I'm torn on this. On the one hand, I do see the fed vs state negative implications of it, but on the other hand, federal overreach has been screwing us so long that it'd be nice for it to go in our favor for once. And setting aside constitutional ideology, it'd mean that I'm able to actually drive outside of New England and remain legally armed - currently I would be a felon at the NYS border, and indeed on my daily commute into Massachusetts absent a Mass out-of-state CCW (renewed annually for $100, unlike my NH one renewed every four years for $10).
All that said, I'd be very surprised to see it actually pass - Schumer and the other anti-gun senators have promised a filibuster and the Reps and Blue Dog Dems might muster a majority, but I strongly doubt they have 60 votes (and it has to survive Pelosi's House, too).
