I never voted for the man, voting for Ford in 1976 and Reagan in 1980, and he was IMO a very ineffective POTUS, way too much of a micromanager with the Iran Hostage Crisis consuming his presidency. But I have a huge amount of respect for him as a person.
It wasn't his presidency that defined him as much as it was his activities afterwards. He was active in peace negotiations, established Habitat for Humanity, stayed out of the political fray. My opinion of him was that he was a helluva nice guy who got in over his head as President.
100 years old. Quite a life. Rest in peace, Jimmy Carter.
