65 historians (people who study what has happened in the past) said that they think that Lincoln is the best president. This was the result, or outcome, of a survey (where people ask questions about a topic to people just to see how to answer them) of the past 42 presidents of the United States. Our last president, George W. Bush, did not do so well in the survey. He came in 36th place. James Buchanan, who did nothing to try to stop the Civil War from happening, came in last.
