William Jefferson “Bill” Clinton was the 42nd President, serving from 1993-2001. He has an IQ of 156 by Simonton’s estimates.
After graduating from Georgetown, winning a Rhodes Scholarship to Oxford University, and earning a law degree from Yale in 1973, Clinton was elected governor of Arkansas in 1978. He went on to win the presidency with Al Gore as his running mate in 1992 and is perhaps best remembered for his efforts brokering peace in Ireland and the Balkans.
