Not that biden won, but if a president elect dies, their VP does take over
The Constitution did not originally include the term president-elect. The term was introduced through the Twentieth Amendment, ratified in 1933, which contained a provision addressing the unavailability of the president-elect to take the oath of office on Inauguration Day.[1] Section 3 provides that if there is no president-elect on January 20, or the president-elect "fails to qualify", the vice president-elect would become acting president on January 20 until there is a qualified president. The section also provides that if the president-elect dies before noon on January 20, the vice president-elect becomes president-elect.
actually even if he is arrested... Section 3 provides that if there is no president-elect on January 20, or the president-elect "fails to qualify", the vice president-elect would become acting president on January 20 until there is a qualified president.
