Frankly, Trump’s policies will have some very strong negative consequences if he follows through on them.

Trump plans to destroy the United States governmental system and become a king, with the power to kill his opponents and remove anyone's ability to ever challenge his hold on power without bringing down the full weight of a multi-trillion-dollar punitive system down upon themselves. Probably he will imprison or kill anyone who tries to disobey him. Also, he's explicitly allied himself with violent foreign adversaries who view us as an enemy that needs to be exterminated.

I would call that negative consequences. It's not guaranteed that he will succeed, but that's what he's planning, and he has some powerful allies who are going to try to help him with it.
