Woodrow Wilson was the worst.
Maybe not for much longer.
Wilson ranks up there as “the worst”. I don’t have the time or inclination to do it, but it would be interesting to categorize them in more detail rather than just “the worst”.
Long term destruction of America vs. blunders. Wilson and FDR would rank up there for long-term problems. I don’t know enough - but maybe even James Madison.
Ineffectual and forgotten presidents - although they might be some of “the best” as they didn’t do much!
While Carter sure messed things up for awhile (gas lines and high interest rates and the messed up Iran hostage deal come to mind); I would have to learn more about the long-term problems that arose from his presidency. I guess not being able to reuse spent nuclear fuel is one.
