Probably Andrew Jackson, a slaveowner piece of shit who committed genocide against Native Americans in direct defiance of a SCOTUS ruling.

Not them, but for all the negative consequences we’ve seen as a result of his policies, Reagan is my pick for the worst US president. So many problems in modern America trace back to things he broke.

We don’t have enough hindsight to say how Trump compares for sure, it’s possible he’ll end up having been worse, even if he isn’t elected again, but only time will tell.
