Yeah but even if he matches 2020, basically Trump turned out the same base as last time and didn’t convince many new people to vote for him. 

Biden went back on his promise to run just once, prevented a real primary, failed at the debate, and left the party with the only option of running Harris. I’ve never been a fan of her politics, but her campaign just didn’t do what it needed to do, which was inspire her base to vote for her.
