It has become clear that this administration will not get anything done in the first two years, Democrats will win back some part of Congress in 2018, and then even less than nothing will get done for the final two years. Then new Democratic leader, Dwayne "The Rock" "Hercules" "Toothfairy" Johnson, becomes President. Trump's only lasting impact besides creating the pinnacle of late night comedy for four years will be the Supreme Court Justices he puts in place, and his first one wasn't terrible.
All in all, not too bad for America. We end up with some corporate deregulation and all-time high stock prices, probably some tax cuts for a few years assuming getting "nothing" done is an exaggeration, President The Rock, who will defer to his advisers on any real issues and win back European leaders with his charisma alone, and 1-3 decent but right-leaning Justices taking the place of Scalia, Kennedy and/or Ginsburg.
