You are absolutely correct, instead you'd have the literal fascist Trump instead.
It sucks, but as lang as you guys have the first-past-the-post (2 party) voting system, voting for the lesser evil is the best one can do.
Sorry, but you're not going to get ranked choice voting just by pretending you already have it. FPTP and the electoral college are realities of US politics and the "lesser of two evils" approach is the only realistic way to play the game.
The executive branch is the wrong place to try to achieve ranked choice voting anyway. Vote for legislative candidates who support ranked choice. If nobody is talking about it, call your representatives. Start petitions. Join grassroots organizations. Anything, but don't fool yourself into thinking the path to fixing our issues involves voting for Jill Stein over Biden next year.
I'm not pretending we have ranked choice voting, in fact I know we don't, that's why I vote for candidates that support ranked choice voting.
I'll be voting for the candidate that does in each level of government. The greens would run more congressional candidates if you would support and fund them instead of voting for their opposition.
