But that’s the thing, Trump, despite being a terrible person and president, was genuinely pretty popular with his voter base. They will more than likely come out to vote, despite his popularity declining a bit. However, Biden, while being a relatively sane, levelheaded president, is not really popular. His VP isn’t particularly liked (bad pr or not, that is an issue) and a lot of his voter support seems to be, "well, at least he isn’t Trump. " I find that incredibly scary, as it means in my mind that Biden being re-elected isn’t such a slam dunk as a lot of the DNC seems to project.
