Honestly, we need to dissolve the union at this point. It's just common sense.
Look, it's time for a reality check. When a nation's political culture becomes this dysfunctional, there's no bringing it back, not without some massive bloody civil war that leaves millions dead. What they don't teach you in school is that every written law or constitution is ultimately meaningless. The Constitution does not enforce itself and neither does any law. They all require a certain amount of good-faith interpretation. It is always possible to come up with a strained bad-faith interpretation of any law that will allow you to do whatever you want. But in a healthy political system, this doesn't happen. Both sides practice restraint and realize that their overreach will be answered by overreach on the other side.
But if you lose that? The nation is effectively shattered. The United States, as a functioning democracy, is already dead. It's zombie corpse is just limping along. The president is openly defying the laws passed by Congress. The Supreme Court is openly corrupt, openly partisan, and ignoring the plain language of the constitution. It's all just might makes right now, and both parties view the other as fundamentally wicked and illegitimate.
Once your politics have decayed this much, there is no bringing it back. We need to peacefully dissolve the United States. Will it be easy? No. But we also shouldn't let one of our core national character flaws - American exceptionalism, blind us to the possibilities that exist. Plenty of nations have peacefully dissolved before. And they find ways to negotiate the hard issues like dividing assets, debts, obligations, military forces, etc. This has been done before, and it can be done again.
When this comes up, the "umm aktually" crowd also comes out of the woodwork. They'll point out that there's no actual constitutional mechanism to do this. These people are blind or have been asleep the last six months. You would think they would learn by now that all it takes to do something is that there not be anyone there to stop you.
We should grant all 50 states full independence. Just disband the existing federal government entirely. Let the states then come back together in whatever new nation or nations they want to form. How can this be done legally? Simple. Someone just needs to run for president on the platform of national dissolution, saying, "I'll grant all 50 states independence. I'll fire every federal employee, and I will not use any military force to stop all the states from seceding." And then they get elected and simply do that. Congress or SCOTUS can complain all they want; it won't matter. That candidate if elected would have an overwhelming political mandate, and there would be no way to stop them. Some may whine that it's unconstitutional, but who cares? It's pretty obvious by now that the Constitution is broken, obsolete, and no longer worth respecting. We're walking away from that broken obsolete piece of trash. We can do better.
