Maybe, but the alternative is what? Trump wins and hopefully doesn't do all the authoritarian things he's promised to do? There's a non zero chance that if Biden doesn't win next year there won't be free and fair elections in 2026 and 2028.
Trump wins and tries to act like an authoritarian but everything either dies in congress or gets slapped down by courts.
I'd hope so and that might even be likely, but given how Trump has already succeeded in taking over the Republican Party and a slow degradation of American democracy I'd rather not take the chance. He has never been competent but he still plagues us nonetheless.
There's also all the other damage he could do internationally, empowering Russia and China, stopping any progress on fighting the climate emergency.
