i am skeptical, to say the least.  at this point.

"in common use", historical precedent, etc.  It could work.  But I think we're playing against a stacked deck.  Depends a lot on the next administration, and the one after that ...

This is a great idea for the mid terms. Plenty of single issue voters out there.

The lead case is the New Jersey assault weapon/magazine ban which is currently under review by their en banc court, with an opinion coming out this year.  That will likely be our first federal appeals court win, on AWB and magazines, with 6 Trump judges, 2 Bush judges, and 6 democrat appointed judges on the panel.  All other appeals to date have been loses which is why SCOTUS didn't take it up.  This would be the first win and circuit split resulting in SCOTUS likely taking it up next year.  If it's a total 2A win, New Jersey could decide not to appeal it to SCOTUS.  However SCOTUS has been perpetually holding on to Duncan vs Bonta on California's magazine ban which they can continue to hold until the New Jersey opinion is released.  They could then take up Duncan next year if New Jersey isn't elevated up to them.

So it's possible Hawaii's magazine ban, and possibly our assault pistol ban, could be eliminated sometime in the 2nd half of next year.
