I have absolutely no doubt Trump will declare the election rigged, but I also have no doubt that nobody important will believe him. He'll get laughed out of any court he tries to file suit in. New Congressmen will take their seats in January and those defeated will leave quietly for their corporate board and think-tank "jobs".
Not the first time people couldn't take their seats. Al Franken had to wait seven months, you're far to cavalier about this.
I'll research it more and get back to you on it, hopefully you're right, but you might not be, and we might be knee deep in...."orange tapioca".
