Trump says you won't need to vote if he wins. But here's the thing: It's not just Democrats who should worry. Trump's chaos could destroy the whole rigged system - Republican and Democrat. He might seem like an undertaker of the American democracy, but in doing so he will drown his own ship, too. But we need to help him steer it into the iceberg of organized social anger instead of isolated floes made of any expectations his mostly temporarily deluded and desperate voters may have or some single-cause activisms or culture wars that will only benefit him. Those will be shattered within the first few months of his term, as he won't have COVID to use as a convenient excuse for his failures to not only address, but at least not make worse the organic crisis of the system, like Genocide Joe has had.
EDIT: I'm not saying this to fucking endorse him or passivity. What I mean is that the world does not end at the ballot box and we need to reckon with the possibility of his victory and that there are countless other means of resisting him other than just depositing all our hopes in the Democrats. And that even though resisting Trumpism will not be an easy task, the instability and disappointment that a presidency of establishment's populist enfant terrible, in an era that breeds virtually no statesmen of great stature, is bound to engender, has the potential actually make it easier.
