Expect Desperation from Trump Against Biden
Trump goes to prison if he loses.
That means Trump will do anything to win. He already got himself impeached. He'll lie, cheat, commit crime, create chaos, commit evil, incite violence, rip up the Constitution, use the Intelligence and Judicial institutions which are headed by loyalists to setup and attack Biden and his family, etc.
After all, Trump was fine with tearing young children from their mothers arms and placing them in cages, starving them and denying them basic hygienic items like soap and toothpaste to gain political points with his base.
Don't underestimate an evil and desperate man with no morality.
