Reagan, Clinton, and LBJ are too high.
And why even include William Henry Harrison?
Agree in general on Bush and Obama. They're bad, but not too bad.
ALso I wonder inside if Lincoln is viewed as extremely high and positive as he is cause of the turds all around him. Pierce, BUchanon, and Baldwin lookalike Fillmore were all terrible, and Johnson obviously sucked. But even after that, Grant was terrible, Hayes, Garfield and Arthur were mediocre.
Also I'd drop Adams a good chunk of spots. He was a pretty ****ty president but not terrible. Seemingly their reason to put him that high was his role in the constitution.
I think the top 5 is alright. You can argue the order, I would drop Adams, Reagan, and Madison out of the top 10 and bring in Wilson, Jackson, and Polk. Gotta respect what Polk was able to accomplish as a president that no one really wanted.
IMO you cannot have JFK and Reagan too far apart. You have 2 guys who's primary value is as a cult of personality. So say if you have Reagan at 10, JFK is 9. JFK was a better president than Reagan, but they were really similar.
