Most important person in Lincoln's life

[Wild Bill]

I like the choice of Henry Clay for his political ideas, but I believe the Mary Todd Lincoln aces all out in the end, like her or not. I cannot remember where, and I may be totally wrong, but I swear I read somewhere that she was the real anti-slavery person in the family. She would not be the first person from a slave-holding family to go that route. I believe that she gets credit for a lot of his ambition and his drive for the presidency, too. But I admit to being out my ken here.
