In my opinion, the bad presidents in my lifetime rank like this (with worst at the top — higher on the list worse than lower on the list):
Obama
Clinton
Carter
LBJ
Nixon
Kennedy
Bush II
Bush I
In my mind, only Reagan doesn’t make the list of bad presidents, and the only reason Nixon beats out Kennedy is Kennedy wasn’t around long enough to evaluate completely. Also, I think that there’s evidence that Kennedy was less of a socialist than Nixon.
But anyway, LBJ is way down on the list. Each succeeding Democrat is worse than LBJ. In my opinion.
My list from worst to best.
Obama
LBJ
Carter
Nixon
Clinton
Kennedy
Bush II
Bush I
