Former Vice President Joe Biden recently turned 77 on November 20.

The 2020 field is one of the most diverse in history in terms of age, which has become a focal point for 2020 Democrats. Mayor Pete Buttigieg, 37, for example, is partially centering his campaign on the theme of intergenerational justice, arguing a new generation of leadership can solve the problems facing America.
The US Constitution mandates that a candidate must be at least 35 to be eligible for the presidency. The youngest-ever president was Theodore Roosevelt, who took office at 42 years and 322 days old in 1901.
