Trump was way more unpopular then. He also told his supporters to vote day of. Voting by mail was way easier that year so people that may normally not have voted did, and Trump supporters voted election Day. He basically kneecapped himself.
I’m convinced he would’ve be reelected had it not been for COVID.
That’s been the case since '16. Things need to change at the DNC because maga sure as shit aren’t going away.
