I'll go with Franklin D. Roosevelt. Based upon my understanding of individual service, accomplishments, and the success of the presidency i think if there were to put another face on Mt. Rushmore, Franklin D. Roosevelt would be the best . Any individual who does not state Franklin D. Roosevelt, does not know history. Roosevelt was an awesome president that most Americans had a photograph of in their homes.
Franklin D. Roosevelt removed America from depression, won the World War 2, longest serving USA president and has the best impact of modern day life. I would state Franklin D. Roosevelt is second most prominent president behind Abraham Lincoln.
