There's not going to be a civil war; not today and not anytime soon. America is a fluid economic and cultural zone without dividing lines that could organize political violence. If you look at data, the most significant form of polarization politically is based on intimate individualistic factors like gender and age. Most importantly, no country with a high per-capita GDP has ever had a civil war. 

The logic is simple: Even if you're really mad about something in politics, in America you still have the option of watching the football game and going to Cinnabon. The minimal bread of Cinnabon and circus of the NFL is democratically accessible to the masses on a level unlike anything in human history. To the vast majority of people that rationally sounds like a better option than rotting away in prison or giving up ones life or health for some abstract cause.

Rich countries don't have civil wars, they just yell alot. Maybe a civil war could be organized in the metaverse one day so people can blow off steam.
