What one word character description set President Lincoln apart?

[AussieMick]

I like 'Leadership' ... so tried to think of something better and in doing so tried to identify what could be a weakness of someone that's strong as a Leader. True, it doesnt require humility. And obviously there have been many successful Leaders who are now regarded as appalling human beings.

The important point is 'what set him apart from others at that time'. I suggest Focused.
Anybody can be focused ... I'm sure many of his Cabinet were 'focused' and some of the great figures of the past (Napoleon, Churchill even Stalin) were focused.
Lincoln though stayed focused ... always, as far as I know, on what he wanted to achieve. Without being distracted by others or by big-noteing himself. He used the abilities of others and made decisions and was willing to alter them later if they didnt work out.
