He'll rank at the bottom of Modera Era Presidents along with George W. Bush & Richard Nixon.
Nixon honestly doesn't even look that bad anymore. His corruption is so quaint in hindsight and he actually had some positive accomplishments for the country's future.
It's always possible that Trump will end up being seen that way as well. If the world goes to hell in ways that aren't directly traceable back to him, people might focus on the good economy and lack of new wars, and (with Republican encouragement) forget much of the rest.
If there's another, deadlier pandemic in the near future, it might make his COVID-19 numbers look not so bad by comparison, and the cultists can always claim that "if not for Trump's (really nonexistent) efforts, this new one would have been
even worse". (Basically, the reverse of what Trump and his lackeys so clumsily try with Obama and Ebola and H1N1.) As for his lack of accomplishments... he's already been claiming credit for legislation Obama signed without significant pushback and his future cultists will doubtless do more of the same. (I.e. If UBI happens and is seen as a success, future Republicans will credit Trump's signature on one-time direct payment checks as the start of it, and give him credit for the whole program.) Plus, if you don't look too close, Trump looks sort-of like a GOP ideal: a hyper-wealthy self-made businessman and Renaissance man (real-estate, finance, televion, aviation - he's done it all!) who has turned his tough-talking, no nonsense, outside-the-box, alpha-male talent to public service. He presided over a massive business boom, while his unique approach avoided any new wars with hostile powers while still furthering diplomacy.
It's all nonsense that collapses into fractal awfulness once you start examining it, but there's enough of a shape of a positive story there that you can sell it to someone who wants to believe it. Anyone who says differently is obviously a democratic revisionist trying to smear Trump's name. I don't think it'll actually go that way, though. There's too much audio, video, and other public digital records of him being an ignorant destructive jackwagon.
