So what's the downside?
Most likely the court took the case to cement the doctrine. Then it will be “settled law”.
SCOTUS could have chosen to ignore taking up the case; that they have decided to hear it should at least bring us some happy optimism.
I don’t see a downside to this. If it’s constitutional to do so, we could certainly do with a few less laws; many of which apparently should not have been law in the first place. The one thing that would probably do the most for our country would be to get us back to where the Constitution really is the law of the land. It’s time to realize that our forefathers really did have their heads on straight when they wrote our Constitution. Some Democrats will not like this, but as far as I’m concerned they can go pound sand.
That it would only go back to WW2?
