Depending on how the next four years go I'm on the fence between Bush Jr. and Trump but I'd like to hear from you
Edit:
Top 10 suggestions so far (unordered):
- Andrew Jackson
- Andrew Johnson
- George W. Bush Jr
- Ronald Reagan
- Richard Nixon
- James K. Polk
- Woodrow Wilson
- James Buchanan
- Franklin Pierce
- Donald J. Trump
If it's about domestic damage, then every president who owned slaves or supported segregation still beats him.
E: Also every president who was involved in the genocide of the indigenous peoples of America to an extent more than Trump (IE he probably ties Biden and Obama on this).
