If prison time is not in the cards, then a permanent charge against tRump that forbids him any contact with political parties whatsoever, and he loses the right to make donations as well. It has to be final and for the rest of his stupid life.
If he's stripped of everything political, his base will be gone by 2022.
He won't have any value or clout. But todays republiqans couldn't care less if tRump drops dead on the 6th green, all they want is the voters. They don't want tRump anywhere around.
But the republiqans total dishonesty and nazism to retain those maga voters is on themselves for being corrupt and self centered.
