We just watched War Game. This was a simulation of what could happen if the 2024 is contested like the last one on Jan 6. Only this time the opposition is much more prepared, both the National Guard and the military are compromised (it's estimated that about 7% of National Guard members and a similar percentage of regular military would side with those opposed to the peaceful certification of the election and would resort to provoking violence by the police, Guard and acitve military.
Basically they game it out in real time (given a 6 hour time limit) with Fmr Gov Steve Bullock as President, Fmr Gen Wesley Clark as Chairman of the Joint Chief's of Staff, Heidi Heitkamp, Alexander Vidman, Doug Jones and several others who have had governmental experience.
Bottom line, next January could be very scary
