What happens in November/January is that America will elect as President either a confirmed Sociopath with Fascist and Authoritarian tendencies or a confirmed Narcissist with Fascist and Authoritarian tendencies: America is getting screwed either way, the difference is in the speed of the screwing and whether you're getting smooth talk or dirty talk with the screwing.
Tactically, this battle is lost and has been lost for months now. The vote now only has any power to push for change at a Strategic level: what your vote for or not now can influence, is whether in subsequent elections the Democrat Party will genuinelly fear defeat and hence field a presidential candidate who actually represents his electors or if they feel confident that "our guy is slightly less evil" propaganda always works to secure their Left flank (if it works even with a Democrat candidate who is openly and activelly a supporter of a far-right ideology committing Genocide, they are bound to conclude it always works) in which case they will move even more to the Right and field an almost-Trump candidate.
Keep voting for lesser evil no matter what and the Democrat Party will keep giving you increasingly evil options.
