Carter was a lousy president but is a great a humanitarian. Can't say much for the others you mentioned.
How so?
Surely you don't believe this fool digs into his own pockets and distributes largesse to the poor?
Perhaps you're thinking about the Habitat For Humanity, where he drives nails (to promote his legacy) into tar-paper shacks.
Perhaps his humanitarianism became apparent when he left the Baptist Church because of their rigid stance on abortion and homosexual behavior.
He was and is a lousy American.
Oh, I almost forgot the Panama Canal giveaway.
