George Washington. He was the Father of our Country. He led the Revolutionary War and won our Independence. He set the standard for peaceful transition of power. He could have been a King but turned it down. Lincoln was great too because he preserved our nation but without Washington we wouldn't have had a nation.
Although I don't claim to know much about either, I'd say Lincoln because he seemed to have more determination & purpose. Washington seemed to become president by default, which is not to say he wasn't a good president. It seems that Lincoln was more charismatic & able to manage people with respect. Looking forward to the movie.
