There were a couple in the 80’s and 90’s (Coverdell and Mattingly).
Also, GA Dems like Zell Miller and Max Cleland were to the right of pretty much all of the current GOP Senators.
You’re right. Paul Coverdell was a wonderful man, who iirc died in office. Mattingly barely rings a bell with he. Overdell’s replacement, Dem Zell Miller, shows how far from normal today’s Dems are.
