September and October 2020 – Presidential election debates Tuesday November 3, 2020 – Election Day Monday December 14, 2020 – Electors cast their electoral votes Wednesday January 6, 2021 – Congress counts and certifies the electoral votes Trends Previous experience Among the 45 persons who have served as president, only Donald Trump had never held a position in either government or the military prior to taking office. The only previous experience Zachary Taylor, Ulysses S. Grant, and Dwight D. Eisenhower had was in the military. Herbert Hoover previously served as the Secretary of Commerce. Everyone else served in elected public office before becoming president, such as being vice president, a member of Congress, or a state or territorial governor. Fifteen presidents also served as vice president. Six of them – John Adams (1796), Thomas Jefferson (1800), Martin Van Buren (1836), Richard Nixon (1968), George H. W. Bush (1988), and Joe Biden (2020) – began their first term after winning an election. The remaining nine began their first term as president according to the presidential line of succession after the intra-term death or resignation of their predecessor. Of these, Theodore Roosevelt, Calvin Coolidge, Harry S. Truman, and Lyndon B. Johnson were subsequently elected to a full term of their own, while John Tyler, Millard Fillmore, Andrew Johnson, Chester A. Arthur, and Gerald Ford were not. Ford's accession to the presidency is unique in American history in that he became vice president through the process prescribed by the Twenty-fifth Amendment rather than by winning an election, thus making him the only U.S. president to not have been elected to either office. Sixteen presidents had previously served in the U.S. Senate, including four of the five who served between 1945 and 1974. However, only three were incumbent senators at the time they were elected president (Warren G. Harding in 1920, John F. Kennedy in 1960, and Barack Obama in 2008). Eighteen presidents had earlier served in the House of Representatives. However, only one was a sitting representative when elected to the presidency (James A. Garfield in 1880). Four of the last seven presidents (Jimmy Carter, Ronald Reagan, Bill Clinton and George W. Bush) have been governors of a state. Geographically, these presidents were from either very large states (Reagan from California, Bush from Texas) or from a state south of the Mason–Dixon line and east of Texas (Carter from Georgia, Clinton from Arkansas).
