James K. Polk (IQ 130.2)
For some reason, this president is often overlooked. He made a massive influence during the Mexican–American War by gaining more land for his country. He also turned America’s financial standing into one of the best it has known.
Grover Cleveland (IQ 130.9)
Money isn’t everything. Grover Cleveland didn’t have enough money to attend college as he was growing up, but that didn’t prevent him from obtaining a law degree and then a U.S. presidency. He was noted for his ethics and honesty.
