Ranked-choice voting in the United States
Since 2002, Instant Runoff Voting has been adopted in a number of U.S. cities. Most of these adoptions are pending implementation; however, as of November, 2007, 33 elections have been held in four cities or towns: San Francisco, California, Burlington, Vermont, Takoma Park, Maryland, and for a one time Pilot Program [4] in Cary, North Carolina.
This article lists the cities in the order of year adopted, the status of implementation, and the results of elections held.
2002
San Francisco, California
In March 2002, an initiative backed by the FairVote passed by referendum making instant runoff voting the means of electing candidates for the Board of Supervisors and most citywide offices in San Francisco. It was first used in that city in October 2004 for YouthVOTE, an election held throughout San Francisco’s public schools which elected the SF school board's student delegate, [5] after that it was used in the November 2004 supervisoral races. Instant runoff voting played a decisive role in at least one city election in 2004, 2005 and 2006 ([6]). Exit polls [7] by San Francisco State University have shown strong support for the new system from all groupings of voters.
Note: The San Francisco Department of Elections prefers the term Ranked Choice Votingbecause "the word instant might create an expectation that final results will be available immediately after the polls close on election night. The Department instead chooses to wait until most absentee ballots have arrived before running instant runoff ballot counts.)
Results
Ranked Choice Voting has been used since 2004 to elect its Board of Supervisors and major citywide offices. This implementation allows the voter to rank three candidates and uses the IRV method of candidate elimination.[1]
As of November, 2007, there have been 20 elections using the RCV ballot.
2004 San Francisco results
There were four elections that used the Instant runoff process; Districts 1,5,7, and 11.
- District 1: There were 7 candidates, reduced to 2 candidates in 4 rounds. The winner finishes with 48.67% of the total votes, runner up with 41.44%, and 9.89% of the ballots were exhausted.
- District 5: There were 22 candidates, reduced to 3 in 19 rounds. The winner finished with 37.63% of the vote, and two runners up with a combined 36.74% of the vote, with 25.63% of the ballots exhausted.
- District 7: There were 13 candidates, reduced to 2 in 11 rounds. The winner finished with 43.72% of the vote, to 33.19% for the runner up and 23.12% exhausted ballots.
- District 11: There were 8 candidates, reduced to 2 in 6 rounds. The winner finished with 46.08% of the total votes, to 32.91% for the runner up, and 21.01% of the ballots were exhausted.
The District 5 results are included below as the largest election from 2004 and most round of counting. The elimination table shows the candidates reordered by their elimination. The elimination process was stable for the highest 5 candidates, holding their same plurality ranking each round despite the 19 rounds of elimination and transfer votes.
The IRV elimination process was halted when the plurality candidate reached 50% of the eligible ballots, but only 37.6% of the total ballots. This stopping point is pragmatic for picking a winner, BUT fails to show how many votes the winner had compared to only one runner up candidate.

Notes:
- The source summary listed Eligible ballots each round as nonexhausted ballots. This is shown here.
- The source summary listed Exhausted ballots as ALL exhausted ballots, including ballots with no marks at all on the election. This table subtracts exhausted the 4146 ballots that supported no candidates to be consistent with other tables in this article.
- Similarly the source listed Total ballots to include eligible and exhausted ballots. Here the no-mark ballots were also removed from the total.
- The final column "Plurality candidate %" is based on votes for the top candidate divided by this adjusted total ballots.

Takoma Park, Maryland
The city of Takoma Park, Maryland adopted instant runoff voting for city council and mayoral elections in 2006. [citation needed]
Results 2007
In January 2007 the first IRV election was help to fill a city council vacancy in a 3-way race with a majority winner in the first round. Voters selected Reuben Snipper with 107 votes (52.7%), defeating Eric Hensal with 72 votes (35.5%) and Alexandra Quéré Barrionuevo with 23 votes (11.3%) and one write-in.)
Snipper said the possibility of using the IRV system changed the race's dynamics. "I had every reason to believe this was going to be a close race," he said. "It meant that when I knocked on a door, if a person indicated they were going to vote for another candidate, I didn't just leave right away. I tried to persuade them I would be a good second choice." [12]
In November 2007 the mayor ran unopposed, and, out of six ward seats on the ballot, one was contested. Runoff provisions were not exercised.[13]

In part to increase awareness of the voting method and to demonstrate it in a real-world situation, the Independence Party of Minnesota tested IRV by using it in a straw poll during the 2004 Minnesota caucuses (results favored John Edwards). Also, the Green Party of Minnesota conducts an annual poll of Minnesota State Fair attendees, where each person ranks their preferences for fair food to better understand how IRV works in a real-world situation. IRV was adopted for mayoral races in Ann Arbor, Michigan in 1974 after a successful ballot initiative sponsored by the local Human Rights Party; the process was used in the 1975 mayoral election.
Political party usage
Independence Party of Minnesota (2004 Presidential poll)
In part to increase awareness of the voting method and to demonstrate it in a real-world situation, the Independence Party of Minnesota tested IRV by using it in a straw poll during the 2004 Minnesota caucuses.[21]
The poll allowed a none of the above option which could not be eliminated. Their rules eliminated one weakest candidate at a time, or all candidates in a tie at the bottom. They continued the elimination until only one candidate remained to confirm that this candidate had more support than NOTA.
This summary table shows the first round, and final five rounds, excluding five rounds during which 18 weak candidates were eliminated.

Proposals not yet adopted
Dozens of states ([9]) have entertained instant runoff voting legislation in recent years. For example, in 2003, an amendment to the California State Constitution was proposed (SCA 14) with wide-ranging goals of election reform, including instant runoff voting for statewide offices. In the state of Washington, activists have been urging adoption of instant runoff voting there for several years; an initiative seeking to adopt instant runoff voting in 2005 failed to garner enough signatures. The city of Vancouver, Washington voted in 1999 to adopt instant runoff voting. The state legislature enacted enabling legislation in 2004, but the city in 2006 chose not to exercise its option. Instant runoff voting has been on a statewide ballot once, in August 2002 in Alaska, where it was defeated.
in the U.S. Congress, the "Voter Choice Act of 2005" H.R.2690 sought to require the use of instant runoff voting for general elections for federal office.
Older usage
IRV was adopted for mayoral races in Ann Arbor, Michigan in 1974 after a successful ballot initiative sponsored by the local Human Rights Party; the process was used in the 1975 mayoral election.[citation needed]
Nonpolitical usage
Instant runoff voting is used in the United States for a growing number of non-governmental elections, including student elections at more than half ([10]) of the nation's 30 leading colleges and universities, as ranked by U.S. News and World Report ([11]).

- Carleton College (Northfield, MN)
- College of William and Mary
- Clemson University
- Cornell University
- Duke University
- Franklin Elementary School
- Harvard
