I think the likely scenario is Trump digging in post-mid terms. This is very likely, given the amount of flagrantly illegal stuff he's got floating around him and his crew.

Then two paths: he's either successful, forming the sort of "managed democracy" you see in Russia etc.

Or he's unsuccessful, and we see what happens. ICE are a militia beholden to the regime. Could get spicy.

Constitutionally, I think the framework that's supposed to check executive power is already shredded, or at least revealed for what it's been all along: pretty much norms.

Good luck.
