Zachary Taylor was the 12th US president, serving for a short period of time after his election in 1849. However, he suffered an untimely death, after which he was replaced by Vice President Millard Fillmore. Interestingly, both he and his vice president share a similar IQ score - measured at around 135. Perhaps in some situations, similarities do attract each other?
Before becoming a US president, he had a successful career as an officer in the US Army (just like other government officials before him), rising to the rank of major general. He became a well regarded national hero due to his victories in the Mexican-American War. This title of national hero won him the election to the White House, despite him having vague and inconsistent types of political beliefs.
