Again, what do you expect from SCOTUS? Do you expect them to throw out each and every slower court ruling? To date, the District Courts have upheld the lower courts due to lack of......well....... everything. The Friday Ruling means that PA can and will certify the vote. That suit was a huge hail mary with absolutely no chance. And Rudy looked like a complete baffoon. The RNC needs to get competent legal representation and Rudy ain't it. It's going fast because Rudy is incompetent from the word go. No wonder the competent legal firms ran screaming from the building.
The SC is the ultimate decider, just like it was in the Bush/ Gore election. In civil suits, you ask the court to allow you to find evidence of your claim. After all, counties and state control their own election system, so it's nearly impossible to find that without a court order or the states cooperation. The lower courts denied the Trump team the ability to do just that. The next step is to present the Supreme Court with circumstantial evidence for them to rule on in depth research.
Whether that will happen or not is anybody's guess. Even President Trump admitted it's a tough call because the SC doesn't have to hear any case at all. If they don't and if Biden does keep his win, there will always be a question mark next to his name as one of our Presidents in this country.
