William Howard Taft – 139.5
William Howard Taft had an IQ of 139.5. He remained the only person to have presided over both the executive and judicial branches of government, although he appears rather low on the list. He later became the 10th Chief Justice of the Supreme Court of the United States after being the president from 1909 to 1913. The 27th president of the United States was William H. Taft, and he was the only head of state who went on to become the US Chief of Justice.

James Buchanan – 139.6
The 15th president has not improved much in comparison to his predecessor. The majority of historians will remember that as president, James Buchanan had made some lofty goals for himself. During his presidency, Buchanan promised to reach the great heights of George Washington. James Buchanan joins the Presidents who had an IQ of 139. He didn’t quite get there, unfortunately.
