I don’t know about eloquence, but I have always liked Lincoln for his quick wit, folksiness, and the fact that he was non judgemental and could see things in a person that others could not. He was confronted once by some politicos and generals who were complaining about Grant having a drinking problem..Lincoln asked what brand of whisky Grant liked. When told that they didn’t know, he said, “Well find out and send a bottle of it to my other generals”.
