There will not be an election in 2024. Biden will declare a National Security Issue and postpone the election indefinitely. Most of congress will be scared to death and return home to their districts. That is when the expression of “Try voting at them” will become the solution.
Any move to cancel the election will spark CW II or RevWar II. People know this and it will not happen. They will cheat, steal, lie but not cancel an election.
