Not to mention this:
“Irregularities in voter registration occurred prior to the day of the election: over 300,000 people were flagged by the state as being ineligible to vote,[230] and 53,000 voter registrations were delayed by Kemp's office without adequately notifying the applicants.[231] These irregularities resulted in allegations that Kemp was using voter suppression to increase his chances of winning the contest.[231]”
