- The margin is the difference between the winner's vote share and the second-place finisher's vote share, measured in percentage points. Zero indicates a tie. Certified official results are used, subject to the contract's Fully-Conducted Elections and accelerated-resolution provisions. For ranked-choice voting, the vote shares in the last round actually conducted are used.
