There's a regime change like "the second TV debate was a clown show, most swing states saw +5% move away from the incumbent, with the usual stronghold states still holding their established positions, and the latest poll listed inflation as voters' top concern."
...and then there's a regime change like "your capital city and every industrial center is firebombed to oblivion, kindergarteners are begging on streets, soldiers are coming back from POW camps to find their home burnt to ground and their whole family dead, and the occupying forces are executing high ranking officers of the previous regime for war crimes, just to drive the point home that their ideology will never be tolerated ever again."
