I see zero chance of the left letting an honest election take place. I suspect a Trump popular vote win and the left using the EC to crown Kammie the winner. That will leave only two possible responses although a mix could happen regionally. Full out CW is unlikely, but a running and gunning is likely, infrastructure attacks, damaged roads, bridges, anything to limit movement. Cities will collapse and be largely unlivable except areas under control of armed gangs.
Passive resistance is the more likely scenario, more 1st responders, military, blue collar worker revolts, destruction and sabotage of state and federal equipment, blocking interstates. Slow rolling aid, food deliveries. Most people will not willingly serve a queen. If the military survives it will have to draft.
This country is a powder keg. No matter how it plays out a working society is not possible.
