In case anyone cares, Mike Kelly's case to SCOTUS was not rejected in full, but in part only. He filed claiming 1) PA was acting unconstitutionally. And 2) asked that SCOTUS halt the certification process until SCOTUS heard the case. Two things. SCOTUS rejected the latter, the former is still on the table. They are requesting a cert to expedite the case, however given TX also names PA in their case, Rep Kelly's case may be heard in conjunction.
I realize that for some the facts, though interesting, are irrelevant, and they would rather believe SCOTUS unanimously rejected that there's voter fraud. For those that value facts, the legal process is open and verifiable. Sworn affidavits under penalty of jail numbering in the hundreds have been filed and are public record. Lots of evidence has been presented, and expert testimony provided. There is plenty to substantiate a case.
And given the historical moment we are in, it would not make sense for SCOTUS to sit this one out for any reason.
And someone remembers when an angry racist tried to block a black man from joining SCOTUS 30 years ago ...
