Yea, I don't think history will look kindly upon Trump. Especially if any of these indictments end up with convictions. He will have his cult following but I think most of the country will continue to dislike him. And as his hardcore supporters eventually die off over time, I think he will be widely known as the worst President to ever occupy the WH. While I appreciate the "outsider" angle, there is nothing he actually did well. He does not have the temperament to govern and his bull in a china shop approach has no place in democracy.
Since you seem to be a Trump supporter, I'm mostly curious in what things you are willing to admit that he did "Incredibly poorly" as you mentioned.
