Multi-Winner Ranked Choice Voting

Multi-winner ranked choice voting refers to the method of voting and counting of the votes for a multi-winner contest, such as city council, school board or legislature when more than one individual is elected at-large or for district elections with multiple representatives within a district. With ranked choice voting, the voter ranks their choices in order of preference. Then, first choices are counted to determine which candidates have exceeded the number of votes necessary to be elected. After the first round of counting, we can determine whether additional rounds of counting are needed to fill each seat up for election.

Example: Electing 3 Seats With Ranked Choice Voting

In this example, there will be 3 winners. In order to be declared a winner, a candidate must receive the threshold (25%) plus one vote.

Candidate A wins in the first round of counting because he/she received more than 25% of the votes cast. Since ranked choice voting is designed to waste as few votes as possible, the surplus votes for Candidate "A" beyond the 25% needed to win will count for those voters' next choice. Since Candidate "A" received 7 votes beyond the winning threshold, those 7 will count for those voters’ second choice, adding three votes to Candidate "C," two votes to Candidate "D," and two votes to Candidate "E."

Candidate "D" has the lowest number of votes and is eliminated. The eight votes Candidate "D" received will now count for voters’ next choice, pushing Candidate "B" over the threshold to be elected.  One vote for Candidate "B" is beyond what is necessary to win, and is therefore counted for the voter’s next choice. Candidate "B" is declared a winner along with Candidate "A," and we have one seat left to elect among the remaining candidates.

The one surplus vote from Candidate "B" counts for the voter’s next choice, putting Candidate "C" over the threshold to be elected (25% +1), making Candidate "C "the 3rd and final winner.
