Street wars like Bleeding Kansas

Unmarked Federal Agents “arresting” people

Attempt to delare national Martial Law, with varying degrees of success depending on if Democratic Governors find their spine and decide to resist or not. We’ll see if this “Federalism” thing means anything

US dominance degrades, EU and China compete to become the new superpower in place of the US.

Drone Bans (because the shooter at trump’s rally reportedly used a drone), and donnie is probably scared of drones. A de facto drone ban does not need to go through congress, he’ll order the FAA to impose a nationwide no-flyzone for drones. It will illegal to fly drones and the drone hobby will be gone (for at least 4 years)

Potentially widespread usage of zero day exploits. Governments tend to only use it for high profile targets, but trump sees enemies everywhere, his administration might be crazy and start using those malware with less restraints. We could have a worldwide “Wannacrypt” moment where every phone geta a Pegasus and its so widespread that it dominates the news cycle. They’ll pull the voter registrations of anyone who registered as Democrat. Send a Pegasus to the phone numbers on record, probably also send malicious attachments to their emails. Then play it off as a “Rogue Employee” of the NSA or “Democrat Sabeteur”.

There will be a pipe bomb sent to a high level government official, it may or may not explode, then trump declares martial law over it.

jd vance might plot against trump, if trump dies, vance then blame Democrats for it and declare Martial Law and order arrest of Democrats.

etc…
