As a non American, I don't think you can get back from this unless you get rid of the 2-parties system. Identity politics is a big component to what compelled individuals to operate against their own interests and those of their country. Good luck, though.
Two-parties system naturally evolve.
Get rid of money, punish lying, decrease the power of the Executive branch…
Lots to do, but getting rid of the two party system is a pipe dream.
I am not an American either, but there is a great deal of work on this subject, and the two-party system is actually one of the most resistant to single-individual or single-party takeover. The reason is that multi-party systems are vulnerable to having a party in power 'promoting diversity' (or something similar), in order to disempower all their opponents, while making it look like they're allowing for more views. Examples of this include quotas for minority representation, and (strategically designed) multi-member voting districts.
