In the modern era, Carter was the first president to openly publicly denigrate his successor in office. He has never possessed one bit of class or humility. His medical condition is between him, his God, and his doctors so no comment on that. He is and has always been despicable as a US citizen.
By no means have I ever thought highly of Jimmy Carter. I remember him as governor of my state. I was only commenting on his action to allow the Shah here for medical treatment in response to a post that implied he didn’t.
