1. He was a war criminal who funded death squads and terrorists in the Americas and in the Middle East
2. His trickle down economics was a disaster that widened economic equality.
3. He ignored the AIDS crisis
4. He was a racist
5. He supported gun control (as a conservative btw) because black people were using them
I don't care whether he was nice, charismatic or had decorum. His policies were disastrous for the US and the world.
