First of all, new iPhones release in less than a month. Not in the smack middle of November.
Second, I don't know if you are oblivious of the situation or what, but the US is a powder keg in a way it never was since possibly the civil war. The country is incredibly polarized down to the very base, with two pretty distinct factions that are in disagreement on pretty much everything. There are also a lot of very invested and very radical people on both sides, who won't react to a loss with a "eh, whatever" and just go on with their lives. To this, you should add record-breaking unemployment, financial uncertainty and stress due to having to work and live with covid.
All of this combined can easily push people to a point where they might feel like they don't have much to lose, and they might as well go out and burn building/shoot other people if the they believe this will hurt the other faction more than theirs.
On top of a situation that is fucked up to begin with, Trump has been doing everything he can to poison the well and create confusion and uncertainty about the legitimacy of the election, and this already led to a situation where no matter who wins, the other side will have lots of excuses (legitimate or not) to claim fraud and refuse to accept the result.
This is a likely preview of what happens if Trump wins ("4 more years of this fascist? Not a chance"):
This is a likely preview of what happens if Biden wins ("the DemonCrats won't force me to wear a mask!"):
Of course, the other side will very swiftly reply in kind.
