The only two I could find were John Adams and Taft. Adams was appointed Chief Judge of the Massachusetts Superior Court in 1775, And Taft was judge to the Ohio Superior Court and a judge on the United States Court of Appeals for the Sixth Circuit. Truman was a county judge in Missouri, but it was an administrative position similar to a county commissioner rather than a judicial position.
As to judge Judy, I wouldn’t trust her to judge a dog show or preside over a PTA meeting.
I think if Nebraska ever loaned Iowa a thousand dollars and Iowa said it was like totally a gift not a loan and also Nebraska’s been harassing Iowa and needs to get over itself and is just pissed off because Iowa is seeing Kansas now, Judge Judy would be a great president.
Otherwise no.
If by “good” you mean, drive foolsguinea to assassination by her sheer annoyingness, then, maybe.
Just because she is spitteling all over people she thinks are lying doesn’t mean all of them are lying. Maybe some of them are, but even a stopped watch is right twice a day.
