Who is the worst president in the history of the United States according to Donald Trump? That depends on who Trump is talking about. NY1 is reporting that Trump said that Bush was the worst president ever.
"McCain, really, that was almost an impossible situation," said Trump. Bush has been so bad, maybe the worst president in the history of this country. He has been so incompetent, so bad, so evil that I don't think any Republican could have won."
Here's Trump on Sean Hannity saying Jimmy Carter was the worst President, but Obama has him beat.
