There's going to be a new twist.
If they parallel the TX law CA will make it illegal to sell handguns, say. But the state won't enforce the ban, they'll say any individual can sue a seller in civil court and if they win the suit they'll get $50k.
That's the new twist TX is using, and so far it's worked since it isn't the state enforcing the law.
I think the tactic will ultimately fail because in the long run SCOTUS won't let Constitutional rights be skirted like this, but for now Doodle's right. If it works against abortion legally it can work against any right.
Two holes are apparent:
1) A ban on selling handguns would certainly be overturned by the current SCOTUS court, and quickly.
2) The litigant would have to get a win on the suit, and that is certainly no lock.
