Ranking Example - Which is your preferred method of ranking?

This is a ranking example with no quorum defined using the Instant Runoff algorithm.  

Winning vote can be calculated using the following voting algorithms:

  • Instant Runoff
  • Borda Count
  • Condorcet

Instant-runoff voting (IRV), also known as the alternative vote (AV) and ranked choice voting, is a voting system used to elect one winner from a pool of candidates using preferential voting. Voters rank candidates in order of preference, and their ballots are counted as one vote for their first choice candidate. If a candidate secures a majority of votes cast, that candidate wins. Otherwise, the candidate with the fewest votes is eliminated. A new round of counting takes place, with each ballot counted as one vote for the advancing candidate who is ranked highest on that ballot. This process continues until the winning candidate receives a majority of the vote against the remaining candidates.

The Borda count is a single-winner election method in which voters rank candidates in order of preference. The Borda count determines the winner of an election by giving each candidate a certain number of points corresponding to the position in which he or she is ranked by each voter. Once all votes have been counted the candidate with the most points is the winner. Because it sometimes elects broadly acceptable candidates, rather than those preferred by the majority, the Borda count is often described as a consensus-based electoral system, rather than a majoritarian one.

A Condorcet method is any single-winner election method that meets the Condorcet criterion, that is, which always selects the Condorcet winner, the candidate who would beat each of the other candidates in a run-off election, if such a candidate exists.

In modern examples, voters rank candidates in order of preference. There are then multiple, slightly differing methods for calculating the winner, due to the need to resolve circular ambiguities—including the Kemeny-Young method, ranked pairs, and the Schulze method. Almost all of these methods give the same result if there are fewer than 4 candidates in the circularly-ambiguous Smith set and voters separately rank all of them.
