Margin of victory is calculated as the absolute percentage point difference between first and second place finishers. For two-candidate races, this is winner's percentage minus runner-up's percentage. For multi-candidate races, only the gap between first and second counts. For ranked choice/instant runoff elections, the margin from the final round is used. If no candidate wins a majority in Georgia and a runoff is held, the margin from the December 1, 2026 runoff is used. If official results aren't available by the deadline but at least 95% of expected vote is counted, preliminary results are used. In case of identical margins (tied to the hundredth of a percentage point), tied options split the payout equally. Postponed elections or those without sufficient results by the deadline resolve to No.
