Of course the fed judiciary is going to over rule the states. The point is what occurs in the field when the law is tested. I suspect it’ll end in a shoot out or nearly so. Then there’s the state response...will they roll over or give the fed the single finger salute? The various states presumably didn’t go thru this exercise just to play dead. I think things are nearly at a tipping point and it won’t take much more from DC to start some real trouble.
You might want to consider American history, 1861-1865. It was called The Civil War, and it did not end well for the losers.
