I voted for Washington. He is essentially the Julius Caesar of America. A brave general, who defied all odds, to help a proud, rag-tag army, to ultimately defeat the mighty British Empire.
He also had the nuts to dive into uncharted waters, and become America's first ever President Of The United States. This was when the President had true power, and not just a puppet on strings for a specific party or sponsors.
Washington was both the first, and the best President.
