The Consequences of a Sitting President's Death During Reelection Campaign

If a sitting president dies while running for reelection, the vice president, in this case Kamala Harris, would assume the presidency. From an electoral standpoint, Harris would replace Biden as the Democratic presidential candidate, but his death would likely open the door for other Democrats to enter the 2024 race. State election officials may need to adjust filing deadlines to allow new candidates to enter the race. If the president died after securing their party's nomination but before Election Day, both the Democratic and Republican parties have guidelines in place for selecting an alternate nominee.
