The incumbent president, a former president, and four future presidents were all candidates, to some degree or other, for president or vice president in that election:
- Theodore Roosevelt was angling for the Republican nomination to return to the White House when he died suddenly in 1919.
- The incumbent, Woodrow Wilson, subtly let it be known that he would accept the Democratic nomination for a third term. Concerns about both his physical health and his political health prevented his party from taking him up on that.
- Senator Warren Harding, Republican of Ohio, won the 1920 presidential election.
- Governor Calvin Coolidge, Republican of Massachusetts, won the vice presidency as Harding's running mate. Coolidge became president in 1923, when Harding died.
- Franklin Roosevelt was the vice presidential candidate on the unsuccessful Democratic ticket. He, of course, was elected president four times, beginning in 1932.
- Herbert Hoover was a candidate for the Republican presidential nomination. He served as secretary of commerce under both Harding and Coolidge, and was then elected president in 1928.
