Permanent. Loss. Of. US. Citizenship. Escorted to FederalEx planes fueled up and waiting to permanently transport them to whatever country that will have them, with the sure promise of eternal US tracking of their domicile abroad, and rapid arrest and the serving of a full sentence (held in abeyance) if they ever set foot on US soil anywhere again in their lifetimes.
The key to this would be to pick the first people that you know will attempt to flee the country. Cohen leaps to mind. That gives you the onus to say, "Hey, he tried to run, and we're not imprisoning him, we're simply stripping him of US citizenship, which he has forfeited."
You FederalEx a few big names 3 or 4 times, and every last m'fing Libtard, every Swamp rat, every Derp Stater, will fall into line post-haste. "Yes, Mr. President, what can we do for you Mr. President, so sorry about that lawfare, Mr. President."
I am 100% serious.
interesting (article III tribunal + permanent exile sentence(s))
I believe Trump won't be allowed back into the White House without CWII.
