Question is, will it be enough to stop that stuff from coming back. I'm not optimistic atm.

Let's see what a former slave had to say about that.

Power concedes nothing without a demand. It never did and it never will. Find out just what any people will quietly submit to and you have found out the exact measure of injustice and wrong which will be imposed upon them, and these will continue till they are resisted with either words or blows, or with both. The limits of tyrants are prescribed by the endurance of those whom they oppress.

--Frederick Douglas

In other words, it's going to be up to us whether it comes back or not. The constitution alone cannot and does not determine the morality of the laws it contains, that's up to the people. The tyrants will always seize as much power as they're able.
