The best U.S. presidents were Abraham Lincoln, George Washington and Franklin D. Roosevelt, according to the American Political Science Association's 2014 survey. The survey also ranked Theodore Roosevelt and Thomas Jefferson in the top five best presidents.
Abraham Lincoln was president from 1861 until 1865. He freed slaves with the Emancipation Proclamation during the third year of the Civil War, and he was the last president to make battlefield strategy decisions during a war. He gave very eloquent speeches, including the Gettysburg Address.
George Washington faced both international and domestic threats during his presidency from 1789 to 1797. He set the standard for all future presidents while helping the young America expand and evolve into a world power.
Franklin D. Roosevelt served from 1933 until 1945, making him the longest serving president. During the first 100 days of his presidency, he pushed 15 bills through Congress, and these bills later formed the base for his New Deal to bring the country out of the Great Depression. He met with Winston Churchill and Joseph Stalin to negotiate plans for post-World War II Europe.
