You're assuming too much active agency on the part of voters on the American political process. Politics does not happen on election day. Voting does not deliver results. People who (rightfully) did not like Joe Biden because of literally his entire political career but voted for him anyway got what to show for it? Kids still in cages now 3 years later and Roe v Wade overturned without a fight and used as a fundraising tool by the craven ghouls in the Democratic Party.

It is a waste of time and energy to vote for Joe Biden, much less try to convince other people to vote for him. If an American slide into fascism is inevitable, he and the Democratic Party are not only incapable of doing anything about it, but unwilling to.
