I think there is honestly a good chance the SCOTUS refuses to save him. I think this is because he misunderstands they have no loyalty to him for appointing them, their loyalty is to the American liberal capitalist institutions and the capitalists they keep in power.

I think enough injustices on the Supreme Court are going to be convinced by Roberts that they have to protect the institutional legitimacy of the SCOTUS over Trump and will refuse to intervene. Also Biden has talked about reforming the court but they know he's a cuck who will form a bipartisan commission and may not even change anything, if they try and steal the election for Trump the next person they get may not be and doing this for multiple states is a bit different than just one state and it may be too much and they may fear it will cloud their legitimacy which is already hanging by a thread with Democrats thanks to ACB's appointment. Doing things like overturning Roe v Wade and protecting corporate interests is more important than keeping in office the orange man who is bad at imperialism and threatening to rip down the stage curtail that hides the machinery to expose it as all nonsense. As an institution with power only by the fact that people respect it, it is very much invested in keeping institutional respect going.

That said they could still do it but the way things are going they may not get to the case before Biden wins or gets enough votes that Trump has no path to victory remaining.
