No, he wasn't a great politician, but was a better person that every president after him, combined.
I'll personally take a better, honest and more polite person over anything else.
Exactly. I lived during his Presidency, and he had his problems as President, but he was the most decent and honest man to hold office. When he left, it hadn't changed his fundamental character and he went on serving others.
As an example of his faith and honesty, if not political acumen, when he was asked for the famous Playboy interview whether he every cheated on Roslyn, he admitted to lusting after women in his heart and that was the same as cheating in his view. He was excoriated by many for that, and yet it showed both his honesty and deep abiding faith.
A friend of mine who lives in the US hated him as President, and years later met him in Plains (where he was often seen just walking around) and said afterwards he was one of the most decent, honest and genuine persons she has met.
RIP, Jimmy and fair winds and following seas...
