So I saw it tonight. It's a really well made film. There's a certain scene that's one of the most tense and disturbing ones I've seen in a major film in quite some time...if you've seen it you know exactly which one I'm referring to.
So a couple things I should point out (no major spoilers but if you're certain to see it you should probably stop reading here):
-The lack of ideological cohesion in the rebellions is intentional. The movie kind of goes out of its way to not be about Republicans vs. Democrats or left-wing vs. right-wing in the civil war. We do know the President is an authoritarian (he's mentioned to be in his third term and there's a reference to him disbanding the FBI, likely to replace with his own secret police) but no party or ideological affiliation is granted.
-The main characters are a team of journalists who are not affiliated any of the sides. None of them ever touch a gun for the entirety of the movie and only one actually kills anyone. There's actually a scene relatively early where they're embedded with some sort of militia fighting uniformed soldiers getting pictures (and who commit war crimes), but it never explicitly says what side those guys are on or which side they're fighting. This is intentional. In fact all of the combatants in the movie up until the ending's side is unclear and not stated. Even one of the main characters is said to have risen to prominence over her coverage of the "Antifa massacre"...was that a massacre carried out by Antifa or of Antifa? It's never clarified.
-The main theme of the movie is actually not about US politics or the sort of thing that us map nerds would think of but rather about how modern day journalism works and its role in conflicts...it's pretty clear.
This is apparently the map of aligned states in this civil war story:
That about says it all imo
That map suggests some sort of cringe #BothSides nonsense
That actually is kind of what happens, but it's not cringe and not in the way that you're thinking of.
