Extraordinarily unlikely, except in the fantasies of some Russians. If Trump wins, we wouldn't get violent until he actually tried to suspend the Constitution, that would be the most likely instigating event. Not people voting for him and him winning, sadly, fair and square by the laws of our land.
The die-hard Trump supporters are too few in number to do anything if Biden wins. Civil war-wise anyway, they could probably manage a bunch of terrorist attacks if they were angry enough.
He lost the popular vote in his first election and it was just decided that he would get to play President anyway. I don't know how much any of these people are going to care about what the voters want this time around...
For your local power utility in Rural America, that's just your average Wednesday. Somebody gets mad about something and shoots out a couple transformers or yard lights. I've even seen someone actually hit and sever the line once, which is actually pretty impressive considering how small it is. Morons with guns.

That's not how civil war happens. What would happen is that elections results would be put in question (for example some states would challenge the results and there would be disagreement among legal experts as to what to do next), both candidates would start issuing orders and different parts of the military would start obeying different candidates. You weren't that far away from this last time. Fortunately for you the military chain of command wasn't compromised but the government was absolutely ready to abandon the democratic process and split. All that was needed was for Pence to commit to the plan.
Civil wars can happen in a lot of different ways, it's any set of circumstances that leads large swaths of a country to fight other large swaths of it.
People need to organize now, not just to prep for violence but to ensure there's some kind of social safety net to fall back on when shit hits the fan.
This one keeps getting posted, but it's not like it's actually The Future.
The Future is whatever we all make it, and we've got 10 months to make it joyful and wonderful instead of shitty. I'm doing my part to spread joy; and part of that is being optimistic instead of the opposite.
It’s like predicting a stock market crash. If you predict it every year for the rest of your life, you’ll probably be right at some point. Keyword: “probably”
