They will. They never reverse election results. Buddy of mine that grew up in Hunting Beach CA told me of a local election where election fraud was undisputedly proven and they still didn't overturn it.
SCOTUS is so low grade now that they have spent decades perfecting the art of sidestepping rulings that they dont want to make. I dont know enough about this case to guess how they would do it, or to say outright that they will not get in the middle of this election.
