Some portion of the US public will never accept that Biden won this election, in the same way that some portion of the US public refuses to accept "the official version" about 9/11 or coronavirus or vaccine, or still demand to see Obama's "real" birth certificate. Some people will never be convinced that there wasn't fraud on a massive scale. (you can see some of those people online at MLW right now!)
There will be violence, from the same kind of people who were plotting to kidnap and murder Gretchen Whitmer. There will be Timothy McVeigh type terror attacks. There will be people who believe they are fighting to retake the United States from an illegal coup. Trump himself is doing his best to inflame these sorts of people.
Trump has fired the former Secretary of Defense and replaced him. He already has a yes-man running the Department of Justice. How ugly this gets between now and Jan 20 might depend how far Barr and the new Sec Def are willing to go in obeying Trump.
I'm a little nervous about the next 2 months, to be honest. We are going to see some stuff that they will be talking about in history classes in 100 years.
