It better be.
The NRA is still pushing for a Congressional repeal of the Ban., with one My Senators introducing the repeal.
That would prevent a Supreme Court ruling. There isn't going to be a better case in a good long time. The folks who initiated the case are "clean", not criminals, they have violated no law, nor even gun "laws" with the "color of law".
Miller, the last definitive ruling by the SC, was a bad case, and "Bad Cases Make Bad Law", especially when one side doesn't even put in an appearance or even a brief at the Court.
I doubt its chances with this Congress. Wasn't it proposed in the last Congress?
