Jimmy has to battle Clinton for the honors of worst President. It's almost a dead heat, but Jimmy's just plain stupid...while Clinton's a sociopath.
Clinton had the easiest foreign policy burden of any president since Hoover, and, like Coolidge, presided over a strong economy through almost his entire two terms. We are fortunate that this nation did not experience any major foreign or domestic crisis during the Clinton presidency.
Clinton had the benefit/restraint of a republican controlled congress for six of his eight years that kept him from driving the country into ruin. Jimmy had no such restraints and look at what happened.
