Grover Cleveland – IQ 144

Here is another interesting man on our list. With 144 IQ, Grover Cleveland’s two terms in the White House should not come as a surprise. But not many people know that he served two non-consecutive terms in office, making him the only President to do so. Grover slowly rose to the high ranks throughout his political career, starting as a sheriff in New York County and was then later elected as the mayor of the city.

Cleveland’s fiscal conservatism and crusade of political reforms made him the sweetheart of the US conservatives of that time. Plus, fighting corruption, bossism and patronage were among his most lauded moves.
