William Howard Taft – IQ 139.5

William Howard Taft’s IQ hovered near the 140-mark, indicating that he was more than capable of running the ship. Most of his policies and other welfare measures ended up flying under the radar, while his contributions as a chief justice do get due credit.

Many historians feel that Taft was probably cut out for something else other than being president. In some great detail, the man went on to explain how dissatisfied he was with his time in the White House – Sounds quite like the story of an average American worker!
