The 44 Dumbest U.S. Presidents Ranked By IQ

20. Grover Cleveland: 144

Grover Cleveland was the only man to ever hold two separate presidencies with a different leader in between. Cleveland, considered to be the 22nd and the 24th presidents of the U.S., was not formally educated. Instead, he took the same apprenticeship Fillmore had. He is the only president to share Trump’s 144-point score.
