It looks like the whole machine is uniting to kick the orange klan wannabe out but if that happens, without any convoluted court actions, if Biden hammers him for example, I think "they" will start trying to portray the Binden administration as this great recovery from a momentary lapse of reason whereas it will just be neo-con business as usual, or as usual as can be in the Covid era. I also think they are trying to slip Harris in via the back door but we'll see.
If it's close (with or without lots of vote fiddling) and the courts get involved it could go up in flames. All indications are that it will be a record turnout which usually favours Dems but who knows these days?
