Here's my predictions for the upcoming few years: balkanization. The US has already started fragmenting into Blue States and Red States. I would be willing to bet it will further fracture into Blue/Red cities/counties. The midterm elections will be an utter shit show. Candidates will fail to concede should they lose, and many will cry foul. Like, all of them. In hotly contested areas, I'd be willing to bet incumbents that are beaten won't step down, and many places will have two politicians claiming they're both filling the same seat. I can't wait to see the fist fights. I would be willing to also bet militias become more prominent and will start to function more and more as mercenary groups. Either way, migrations to like-minded areas will increase as more states bring cases against unenumerated rights and SCOTUS strikes down precedents protecting them. They've already said they will. States will increase their power, the fed will decline further. In Colorado River Compact states I expect violence as climate change impacts habitation and economic options. Fortunately the morons calling the shots have no idea how to deal with this and lack basic skills of compromise, so an issue that could be mitigated will instead be escalated.
Should the GOP take both houses, Biden gets impeached on Day 1, not that it matters. I would say Trump continues to tease a run in '24 as long as possible to generate revenue, because he knows he has no actual chance. There's no way he runs again unless there is an absolute sweep of total retards like Greene and Boebert coming into congress. Trump in '24 would be a disaster for the GOP. Another Trump term would start like the Ba'ath Purge of '79. Nothing would get done because it would just be Trump Unleashed. I can't see the Old GOP Guard letting that happen at any cost. Cruz of course will give it another go, but it's DeSantis. And it's going to be an utter joy watching him eat Trump alive.
2024 will likely be DeSantis vs Newsom (if both parties are smart). Following the trend of more judges, especially SCOTUS justices, supporting Independent state legislature theory, I predict an utter shit show that will make the midterms look like a peaceful transfer of power. Violence at the polls, ballots lost, total chaos. I would stop just short of civil war, but the election will yield not final decision. What happens then is anyone's guess. Presumably some group will have to step in and restore order.
Good luck.
