Seriously stop asking this dumb question. You know what has to happen, it’s just not great to think about because you had life plans. Well, guess what: your plans are dead, and there is a good possibility you will be too.
Congress is categorically useless, and the ultimate judicial authority in the country - and a disturbing proportion of lower courts besides that - have been completely co-opted. And nobody anywhere who has actual power to push back is actually pushing back. I don’t think even a military coup in either direction would help things at this point. I think the US is headed for breakup and balkanization. This goose is cooked, imo.
Yeah my money is on a Soviet style break up, I doubt there will be much fighting during. I also doubt there will be a Russia analogue since there isn't really an equivalent state maybe the great planes could unify but they don't really have the population to be warmongers.
