In the United States, presidential elections are held in years evenly divisible by four (1888, 1900, 1964, etc.). Since 1840, American presidents elected in years ending with zero have died in office, with one exception. William H. Harrison, the man who served the shortest term, died of pneumonia only several weeks after his inauguration.

Abraham Lincoln was one of four presidents who were assassinated. He was elected in 1860, and his untimely death came just five years later. James A. Garfield, a former Union army general from Ohio, was shot during his first year in office (1881) by a man to whom he wouldn't give a job. While in his second term of office (1901), William McKinley, another Ohioan, attended the Pan-American Exposition in Buffalo, New York. During the reception, he was assassinated while shaking hands with some of the guests. John F. Kennedy was assassinated in 1963 in Dallas only three years after his election.

Three years after his election in 1920, Warren G, Harding died in office. Although it was never proved, many believe he was poisoned. Franklin D. Roosevelt was elected four times (1932,1936, 1940 and 1944), the only man to serve so long a term. He had contracted polio in 1921 and eventually died of the illness in 1945.

Ronald Reagan, who was elected in 1980 and reelected four years later, suffered an assassination attempt but did not succumb to the assassin's bullets. He was the first to break the long chain of unfortunate events. Will the candidate in the election of 2020 also be as lucky?
