This should be enough to put certification of the election results on hold.
Certification is the first step in overturning the result. The result can’t be overturned until it is certified, and the poll workers aren’t about to claim any of their ballots are invalid. Certify Cochran the winner, then challenge the outcome.
"That hasn't been my experience."
You would think. But considering who put those people who will certify the election in their office in the first place I'm not holding my breath.
