How did the presidential election in 1960 change politics?

It was one of the closest elections in American history.

The Republican insider was Richard Nixon of California, relatively young but experienced as the nation's Vice-President for 8 years under Dwight Eisenhower. The Democratic newcomer was JOHN F. KENNEDY, senator from Massachusetts, who at the age of 43 could become the youngest person ever to be elected President. Regardless of the outcome, the United States would for the first time have a leader born in the 20th century.
