In my lifetime, Obama or Clinton. It is a tough call. Overall though I would say Obama because when you look at the mess he came in with and how he cleaned it up it is amazing. People may disagree with me, but I am truly grateful for President Obama and will miss him.
George Washington. He had no money, and had no desire for any station at all, just wanted freedom, and was willing to be on the front line with the troops. His kind are gone forever.
