Given that Trump is Trump, something else probably would have come up to affect the election.
Red Eagle discussed how the alt history of covid not existing would've affected the George Floyd riots. How do you (or anyone else if they wanna pipe in) think the riots would've been affected? Would Floyd not have been in the position he was in if not for covid? Autopsies did show he had covid in his system at the time of his death.
There may have been protests, but I don't think there would have been big riots. I think a lot of the rioting was because people were antsy from being cooped up for two months, with a lot of them not having school or work.
