I think my prediction is not far off from yours (sans the Civil War part as the opposition might not even get to fire a single shot): Trump 2.0 will push as far as it can and if SCOTUS rebukes him too strongly, he will completely ignore its decisions given that DOJ will be castrated and sock-puppeted long before summer high court decisions and given that Congress is even less inclined to remove him from office (at least until midterms which seems like an eternity away). On this near future, I wrote a very small satire: https://ionelv.dreamwidth.org/150034.html
