Little Known Facts about Presidential Elections:

1. The first presidential election took place in 1789. There have been 57 presidential elections and 44 Presidents in US history.
   
   
2. In the election of 1800, Thomas Jefferson and Aaron Burr both received 73 electoral votes. Since neither candidate had a majority, the election was turned over to the House of Representatives. Alexander Hamilton intervened in support of Jefferson to break a deadlock in the House of Representatives. This action contributed to the famous duel between Burr and Hamilton that took place four years later, in which Hamilton was killed.
   
   
3. A presidential candidate has won the election despite losing the popular vote four times in US history: 1824, 1876, 1888, and 2000. In 1824, John Quincy Adams lost both the popular and the electoral vote, but the House of Representatives decided the outcome of the election because his opponent failed to secure a majority of electoral votes.
   
   
4. The shortest presidency in the history of the office was served by William Henry Harrison, who died of pneumonia on Apr. 4, 1841, just 31 days into his term.
   
   
5. Grover Cleveland was elected as the 22nd and 24th President of the United States, making him the only President to serve two nonconsecutive terms.
   
   
6. Incumbents have run in 30 of the 56 presidential elections in US history. The incumbent won 20 times and lost 10 times.
   
   
7. Four of the re-elected incumbents served their first terms without being elected because their predecessors died in office (Lyndon Johnson, Harry S. Truman, Calvin Coolidge, and Theodore Roosevelt).
   
   
8. The Constitution did not originally contain term limits. The 22nd Amendment, ratified in 1951, restricted presidents to a maximum of two terms. Four-time president Franklin D. Roosevelt was the only candidate to be elected more than twice (1932, 1936, 1940, 1944).
   
   
9. Eight US Presidents have died while in office. Four were assassinated (John F. Kennedy, William McKinley, James Garfield, and Abraham Lincoln) and four died of natural causes (Franklin D. Roosevelt, Warren G. Harding, Zachary Taylor, and William Henry Harrison).
   
   
10. 14 Vice Presidents have become President; 5 were elected, and 8 succeeded Presidents that died in office. Gerald Ford, who became president when Nixon resigned, was the only person to serve as both President and Vice President without being elected to either office.
    
    
11. There have been 538 electoral votes in each presidential election since 1960. A candidate must win a majority of those votes (270) to win the election.
