I doubt:
US Election 2024 happens
In general, a combination of state or congressional actions could delay elections but not postpone the selection of a president and vice president. The only hard deadline spelled out in the Constitution is the end of a president’s term and a vice president’s term on January 20 of the year following a general election. That same deadline applies regardless of term limits imposed on the president under the 22nd Amendment.
The Constitution’s text requires that a group of electors, commonly called the Electoral College, chooses the next president. If a majority of electors fails to agree on a winner, Congress picks the winner in continent elections held within Congress under the terms of the 12th Amendment.
