Carter is, I would say, the most sincere and honest US president in my lifetime. Perhaps it was the times, had good politicians in Australia back around then too: Gough Whitlam, Don Dunstan (SA).
Anyway, 75 years of marriage is rather impressive, so sincere congrats from this human anyway to Mr and Mrs Carter.
