Round-robin voting uses ranked-choice ballots but calculates which candidates are most preferred by a majority of voters differently from instant-runoff voting. Like a round-robin sports competition, round-robin voting determines how each candidate fares against every other candidate one-on-one, tallying the number of wins and losses for each candidate in these one-on-one matchups. If necessary to break a tie in these win-loss records, round-robin voting looks to the total number of votes cast for and against each candidate in all of the one-on-one matchups—just as round-robin sports tournaments look to an equivalent total point differential statistic to break ties. When used in a primary election as the method to identify the top two candidates deserving to compete head-to-head as finalists in the general election, comparable to the use of round-robin competition as the preliminary stage of a sports tournament, round-robin voting is the electoral system best able to implement the democratic idea of majority rule.
