First, you missed my point. My point that Carter felt completely vindicated after Trump.
As for rating presidents, I personally have 2 criteria, policy and character. My personal view is this:
Carter - Policy: F, Character: A+
Regan - Policy: A+, Character: A
Trump - Policy: A, Character: F
Biden - Policy: F, Character: B+
Everyone will, and should, have their own view. For me, Policy is related more to the total administration in terms of policy actually implemented. Character is more of a personal rating of how the president conducts himself.
Thanks,
Jack
