I'm sure Mr. Lincoln was a good human being at heart and endured more than one could possibly stand in one's life, like losing 2 sons, an unstable wife, etc., but he blew it big time in the War of Northern Aggression, imho. I can count on one hand "great" Presidents, and Lincoln was NOT one of them.
Perhaps, but so was Jimmy Carter a decent human being AND perhaps the worst President.
Not that being good and decent necessarily makes bad ones.
