They'll likely just forever conclude and say that Biden and the LibDems stole the election somehow (I've read several times the excuse that Biden couldn't possibly have gotten 80 million votes because he hardly ever campaigned in public and stayed in his basement for the entire campaign), and they'll start eagerly anticipating Dear Leader running again in 2024 on a grand "Revenge Tour" to restore him to his rightful place in the Oval Office. And the sad part is that he probably will run again in four years (if he's still alive) and he'll easily win the GOP nomination over anybody who runs against him, and he'll have a very good chance of winning the general election if this year's results are any indicator. So his supporters will just switch from "He'll still be POTUS in January" to "He was CHEATED!" to "We'll put him back in office in '24 and gain sweet revenge on all of our enemies!" That's how they think. Good Luck to Biden in trying to govern the nation, as he's going to need it, and then some.
