21. Benjamin Harrison
While not one of the better known presidents, Harrison had quite the mess on his hands when he was elected into office in 1888 over Grover Cleveland. The country’s wounds from the civil war were still fresh, the economy was in shambles, and relations with Native Americans were still unresolved. Harrison held office during the infamous Battle of Wounded Knee and the expansion of the United States with the addition of the Dakota Territories, Montana, Washington, Idaho, and Wyoming. It would be a difficult time for any man to hold office, even one with an estimated IQ of 132.2.
