who is considered to be the best president
Historical rankings of presidents of the United States Abraham Lincoln, Franklin D. Roosevelt, and George Washington are most often the three highest rated presidents among historians. The remaining places in the top 10 are often rounded out by Theodore Roosevelt, Thomas Jefferson, Harry S. Truman, Woodrow Wilson, Dwight D. Eisenhower, Andrew Jackson, and John F. Kennedy. More recent presidents such as Ronald Reagan and Bill Clinton are often rated among the greatest in world opinion polls, but do not always rank as highly among presidential scholars and historians. The bottom 10 often include James Buchanan, Warren G. Harding, Andrew Johnson, Franklin Pierce, Millard Fillmore, William Henry Harrison, John Tyler, Ulysses S. Grant, Zachary Taylor, and George W. Bush. Because William Henry Harrison (30 days) and James A. Garfield (200 days, incapacitated after 119 days) both died shortly after taking office, they are sometimes omitted from presidential rankings. Zachary Taylor also died after serving as president for only 16 months, but he is usually included. In the case of these three, it is not clear if they received low rankings due to their actions as president, or because each was president for such a limited time that it is not possible to assess them more thoroughly.
