Presidential elections were held in the United States on November 8, 1960. The Democratic ticket of Senator John F. Kennedy and his running mate, Senate Majority Leader Lyndon B. Johnson, narrowly defeated the Republican ticket of incumbent Vice President Richard Nixon and his running mate, U.N. Ambassador Henry Cabot Lodge Jr. This was the first election in which 50 states participated, marking the first participation of Alaska and Hawaii, and the last in which the District of Columbia did not. It was also the first election in which an incumbent president—in this case, Dwight D. Eisenhower—was ineligible to run for a third term because of the term limits established by the 22nd Amendment.
Nixon faced little opposition in the Republican race to succeed popular incumbent Eisenhower. Kennedy, the junior senator from Massachusetts, established himself as the Democratic frontrunner with his strong performance in the 1960 Democratic primaries, including key victories in Wisconsin and West Virginia over Senator Hubert Humphrey. He defeated Senate Majority Leader Lyndon B. Johnson on the first presidential ballot of the 1960 Democratic National Convention, and asked Johnson to serve as his running mate.
