The US Supreme Court is not going to intervene in a state law case.
What I’d like to know is if there was this deadline why didn’t they file it on time?
There wasn’t a deadline per se. However, they first had to fight to see the election information so they had grounds to file, with everyone in the establishment arrayed against them. It will not surprise me to see Cochran lose as bitter voters do not support him.
There isn’t a deadline for an election result to be challenqed, if I’m understandinq correctly.
