Now that is completely possible. More countries have had civil war over political disagreements than due to regional differences. Left-right kind of civil war has happened countless times through history. An example from more democratic countries would be Finland and Spain. I can very well see the start of a civil war after next election result if everything goes wrong. If say Trump loses and rejects that he lost the election while FOX and Friends pump up right wing voters and say the election was stolen from them and that people need to take up arms to protect their rights and prevent the deep state from stealing the election from them, then you may very well see a bloody civil war unfold. Nobody with any force on the right is fighting to calm people down. Right wing voters can be whipped into a frenzy and go berserk. Remember these are the very same people who believe Guns are for protecting their freedom. If they feel wronged their logical conclusion would be to grab their guns and start fighting.
