The election is the 59th quadrennial presidential election in the United States.
Voters will select presidential electors who in turn will vote on December 14, 2020, to either elect a new president and vice president or reelect the incumbents Donald Trump and Mike Pence respectively.
The winner of the 2020 presidential election is scheduled to be inaugurated on January 20, 2021.
Biden, if elected, would become the oldest person to serve as president at 78 years old on the day of his inauguration, and the first candidate to defeat an incumbent president in 28 years since Democrat Bill Clinton defeated Republican George H. W. Bush in 1992; in addition, his running mate Harris would become the first woman to serve as vice-president.
If reelected, Trump would be the oldest president to be inaugurated in U.S. history, as he would be 74 at the time of the 2021 inauguration.
This is the first presidential election in which both the major candidates are over 70.
