Nixon. The fourth best President of the 20th century.
What drugs are you on? Nixon was arguably worse than Hoover. He had a super-expansionist monetary policy creating a very nasty recession when Ford started, paved the way for stagflation in the late '70s, was a complete crook, and delayed an end to Vietnam in '68 solely so Humphrey would lose the election.
Nixon was a horrible President and a horrible person.
Reagan is polarizing, but I can see no objective measures in which he's a worse President or person.
