PL - Aside from her looks, Mary Todd Lincoln was also quite insane. Not sure which would be the larger detractor.

If Abe was gay, it does seem that it really doesn't matter at this stage. And if he wasn't, it really doesn't matter either. He was a very tortured man, yet he managed to lead this country through some very difficult times, things that we can't imagine. IMHO, that's all that really matters about him.
