Elections in Vermont |

The 2009 Burlington mayoral election was the second mayoral election since the city's 2005 change to instant-runoff voting (IRV), also known as ranked-choice voting (RCV), after the 2006 mayoral election. [1] In the 2009 election, incumbent Burlington mayor (Bob Kiss) won reelection as a member of the Vermont Progressive Party, [2] defeating Kurt Wright in the final round with 48% of the vote (51.5% excluding exhausted ballots).
The election created a controversy as a result of several election pathologies, after Kiss was declared winner as a result of 750 votes cast against his candidacy (ranking him last), over the objections of the 54% of Burlington voters who had preferred Andy Montroll. [3]
Unlike the city's first IRV election three years prior, however, Kiss was neither the plurality winner (Republican Kurt Wright) nor the majority-preferred candidate (Democrat Andy Montroll). [4] [5] This led to a controversy about the use of IRV in mayoral elections, [3] culminating in a successful 2010 citizen's initiative repealing IRV's use by a vote of 52% to 48%. [6] [7] [8]
The city of Burlington, Vermont, approved IRV for use in mayoral elections with a 64% vote in 2005, [1] at a time when IRV was used only in a few local elections in the United States. [9] The 2006 Burlington mayoral election was decided by two rounds of IRV tallying, selecting candidate Bob Kiss of the Vermont Progressive Party (VPP). In the election, Kiss prevailed over Democrat Hinda Miller and Republican Kevin Curley. With his election Kiss became the second member of the VPP to be elected to the office after Peter Clavelle.
Unlike Burlington's first IRV mayoral election in 2006, the mayoral race in 2009 was decided in three rounds. Bob Kiss won the election, receiving 28.8% of the vote in the first round and 48.0% in the final round (51.5% excluding exhausted ballots), defeating final challenger Kurt Wright (who received more votes than Kiss in the earlier rounds, but only received 45.2% in the final round).

FairVote touted the 2009 election as one of its major success stories, with IRV helping the city avoid the cost of a traditional runoff (which would not have affected the results). They also argued IRV prevented a spoiler effect that would have occurred under plurality. [11] Later analyses showed the race was still spoiled, however, with Wright acting as a spoiler pulling moderate votes from Montroll, who otherwise would have been able to defeat Kiss in a one-on-one race. [12] [13]
FairVote also claimed the election as a success story because 99.9% of voters were able to fill out at least one preference on their ranked-choice ballot. [11] Other election observers questioned this interpretation, after analyses showed 16% of voters cast plurality-style ballots for only one candidate [14] and 7% of ballots did not rank either of the candidates in the last round, leaving them unrepresented. [12] [14]
Some mathematicians and voting theorists criticized the election results as revealing several pathologies associated with instant-runoff voting, noting that Kiss was elected as a result of 750 votes cast against him (ranking Kiss in last place). [15] [16]
Several electoral reform advocates branded the election a failure after Kiss was elected, despite 54% of voters voting for Montroll over Kiss, [17] [18] violating the principle of majority rule. [13] [19] [20]
The results of every possible one-on-one election can be completed as follows:
Andy Montroll (D) | 6262 (Montroll) – 591 (Simpson) | 4570 (Montroll) – 2997 (Smith) | 4597 (Montroll) – 3664 (Wright) | 4064 (Montroll) – 3476 (Kiss) | 4/4 Wins | |
---|---|---|---|---|---|---|
Bob Kiss (P) | 5514 (Kiss) – 844 (Simpson) | 3944 (Kiss) – 3576 (Smith) | 4313 (Kiss) – 4061 (Wright) | 3/4 Wins | ||
Kurt Wright (R) | 5270 (Wright) – 1310 (Simpson) | 3971 (Wright) – 3793 (Smith) | 2/4 Wins | |||
Dan Smith (I) | 5570 (Smith) – 721 (Simpson) | 1/4 Wins | ||||
James Simpson (G) | 0/4 Wins |
This leads to an overall preference ranking of:
Montroll was therefore preferred over Kiss by 54% of voters, preferred over Wright by 56% of voters, over Smith by 60%, and over Simpson by 91% of voters. [5] [21]
Because all ballots were fully released, it is possible to reconstruct the winners under other voting methods. While Wright would have won under plurality, Kiss won under IRV, and would have won under a two-round vote or a traditional nonpartisan blanket primary.
Montroll, being the Condorcet winner, would have won if the ballots were counted using ranked pairs (or any other Condorcet method). [22] Analyses suggested Montroll also would have won under most rated voting methods, including score voting, approval voting, majority judgment, or STAR voting.[ citation needed ]

There was post-election controversy regarding the IRV method, and in March 2010 a citizen's initiative resulted in the repeal of IRV in Burlington. [23] The initially "stagnant" repeal campaign drew renewed interest as Kiss became embroiled in a series of controversies. [24] In December 2009, a group called "One Person, One Vote", made up of Republicans and Democrats unhappy with the election outcome, held a press conference to announce that they had collected enough signatures for an initiative to repeal IRV. [25] [26] According to a local columnist, the vote was a referendum on Kiss's mayoralty; Kiss had allegedly become a "lame duck" because of a scandal relating to Burlington Telecom and other local issues. [25] However, in an interview with Vermont Public Radio, Kiss disputed that claim, [27] and those gathering signatures for the repeal stated that it was specifically a rejection of IRV itself. [25]
Locals argued the system was convoluted, [25] turned the 2009 election into a "gambling game" by disqualifying Montroll for having won too many votes, [16] [28] and "eliminated the most popular moderate candidate and elected an extremist". [28]
The IRV repeal initiative in March 2010 won 52% to 48%. It earned a majority of the vote in only two of the city's seven wards, but the vote in those 2009 strongholds for Kurt Wright was lopsided against IRV. [6] [7] [8] Republican Governor Jim Douglas signed the repeal into law in April 2010, saying "Voting ought to be transparent and easy to understand, and affects the will of the voters in a direct way. I'm glad the city has agreed to a more traditional process." [24]
The repeal reverted the system back to a 40% rule that requires a top-two runoff if no candidate exceeds 40% of the vote. Had the 2009 election occurred under these rules, Kiss and Wright would have advanced to the runoff. If the same voters had participated in the runoff as in the first election and not changed their preferences, Kiss would have won the runoff. [29]
The following decade saw continuing controversy about voting methods in Burlington. In 2011, for example, an initiative effort to increase the winning threshold from the 40% plurality to a 50% majority failed by 58.5% to 41.5%, [30] while in 2019, instant-runoff voting was once again proposed for Burlington by Councilor Jack Hanson but went unapproved by the Charter Change Committee for the March 2020 ballot. [31]
One year later, in July 2020, the city council voted 6–5 in support of a measure to reinstate IRV, but it was vetoed by Mayor Miro Weinberger the following month. [32] The council then amended the measure to apply only to the council itself, which the Mayor accepted, and on March 2, 2021, Burlington voters voted in favor of IRV for its city council by 64% to 36% (8,914 to 4,918). [33] [34] [35] The charter change required approval by the Vermont legislature, which enacted it in May of 2022, and which the governor allowed to become law without his signature. [36] The council in September 2022, the voters in March 2023, and the legislature in May 2023 approved the expansion of use of IRV for mayor, school commissioners, and ward election officers, with first use in March 2024. [37] [38] [39]
The two-round system, also called ballotage, top-two runoff, or two-round plurality, is a single winner voting method. It is sometimes called plurality-runoff, although this term can also be used for other, closely-related systems such as instant-runoff voting or the exhaustive ballot. It falls under the class of plurality-based voting rules, together with instant-runoff and first-past-the-post (FPP). In a two-round system, if no candidate receives a majority of the vote in the first round, the two candidates with the most votes in the first round proceed to a second round where all other candidates are excluded. Both rounds are held under choose-one voting, where the voter marks a single favored candidate.
In social choice theory and politics, a spoiler effect happens when a losing candidate affects the results of an election simply by participating. Voting rules that are not affected by spoilers are said to be spoilerproof
A Condorcet method is an election method that elects the candidate who wins a majority of the vote in every head-to-head election against each of the other candidates, whenever there is such a candidate. A candidate with this property, the pairwise champion or beats-all winner, is formally called the Condorcet winner or Pairwise Majority Rule Winner (PMRW). The head-to-head elections need not be done separately; a voter's choice within any given pair can be determined from the ranking.
Coombs' method is a ranked voting system. Like instant-runoff (IRV-RCV), Coombs' method is a sequential-loser method, where the last-place finisher according to one method is eliminated in each round. However, unlike in instant-runoff, each round has electors voting against their least-favorite candidate; the candidate ranked last by the most voters is eliminated.
In social choice, the negative response, perversity, or additional support paradox is a pathological behavior of some voting rules where a candidate loses as a result of having too much support. In other words, increasing (decreasing) a candidate's ranking or rating causes that candidate to lose (win), respectively. Electoral systems that do not exhibit perversity are sometimes called monotonic.
A Condorcet winner is a candidate who would receive the support of more than half of the electorate in a one-on-one race against any one of their opponents. Voting systems where a majority winner will always win are said to satisfy the Condorcet winner criterion. The Condorcet winner criterion extends the principle of majority rule to elections with multiple candidates.
In social choice, a no-show paradox is a surprising behavior in some voting rules, where a candidate loses an election as a result of having too many supporters. More formally, a no-show paradox occurs when adding voters who prefer Alice to Bob causes Alice to lose the election to Bob. Voting systems without the no-show paradox are said to satisfy the participation criterion.
Instant-runoff voting (IRV) is a ranked voting method used in single-winner elections. IRV is also known outside the US as the alternative vote (AV). Today it is in use at a national level to elect the Australian House of Representatives, the National Parliament of Papua New Guinea, the President of Ireland and President of India. In Australia it is also used for elections to the legislative assemblies of all states and territories except Tasmania and the Australian Capital Territory, and for the Tasmanian Legislative Council.
Later-no-harm is a property of some ranked-choice voting systems, first described by Douglas Woodall. In later-no-harm systems, increasing the rating or rank of a candidate ranked below the winner of an election cannot cause a higher-ranked candidate to lose. It is a common property in the plurality-rule family of voting systems.
Electoral reform in Vermont has been an issue for decades. Changes in electoral practices have altered how election results represent the intent of Vermont voters and influenced debates in other states.
Ranked-choice voting (RCV) can refer to one of several ranked voting methods used in some cities and states in the United States. The term is not strictly defined, but most often refers to instant-runoff voting (IRV) or single transferable vote (STV), the main difference being whether only one winner or multiple winners are elected. At the federal and state level, instant runoff voting is used for congressional and presidential elections in Maine; state, congressional, and presidential general elections in Alaska; and special congressional elections in Hawaii. Starting in 2025, it will also be used for all elections in the District of Columbia.
Instant-runoff voting is a single-winner, multi-round elimination rule that uses ranked voting to simulate a series of runoff elections. In each round, the candidate with the fewest first-preferences is eliminated. This continues until only one candidate is left. Instant runoff falls under the plurality-with-elimination family of voting methods, and is thus closely related to rules like the two-round runoff system.
An electoral or voting system is a set of rules used to determine the results of an election. Electoral systems are used in politics to elect governments, while non-political elections may take place in business, non-profit organisations and informal organisations. These rules govern all aspects of the voting process: when elections occur, who is allowed to vote, who can stand as a candidate, how ballots are marked and cast, how the ballots are counted, how votes translate into the election outcome, limits on campaign spending, and other factors that can affect the result. Political electoral systems are defined by constitutions and electoral laws, are typically conducted by election commissions, and can use multiple types of elections for different offices.
Ranked voting is any voting system that uses voters' rankings of candidates to choose a single winner or multiple winners. More formally, a ranked system is one that depends only on which of two candidates is preferred by a voter, and as such does not incorporate any information about intensity of preferences. Ranked voting systems vary dramatically in how preferences are tabulated and counted, which gives them very different properties. In instant-runoff voting (IRV) and the single transferable vote system (STV), lower preferences are used as contingencies and are only applied when all higher-ranked preferences on a ballot have been eliminated or when the vote has been cast for a candidate who has been elected and surplus votes need to be transferred.
There are a number of different criteria which can be used for voting systems in an election, including the following
A unified primary is an electoral system for narrowing the field of candidates for a single-winner election, similar to a nonpartisan blanket primary, but using approval voting for the first round, advancing the top-two candidates, allowing voters to confirm the majority-supported candidate in the general election.
On March 7, 2006, a mayoral election was held in Burlington, Vermont, United States. Incumbent Mayor Peter Clavelle declined to seek reelection and Progressive nominee Bob Kiss was elected to succeed him.
The 2022 Alaska at-large congressional district special election was held on August 16 to fill the seat left vacant after the death of Republican incumbent Don Young. Mary Peltola was elected in a 3-way race against former governor Sarah Palin and Nick Begich III in the election, becoming the first Alaska Native and woman to represent Alaska in the House.
A final-four or final-five primary is an electoral system using a nonpartisan primary by multi-winner plurality in the first step.
Center squeeze is a kind of independence of irrelevant alternatives violation seen in a number of election rules, such as two-round and instant runoff, for example. In a center squeeze, the Condorcet winner is eliminated before they have the chance to face any of the other candidates in a one-on-one race. The term can also refer to tendency of such rules to encourage polarization among elected officials.

A display of non-monotonicity under the Alternative Vote method was reported recently, for the March 2009 mayoral election in Burlington, Vermont.
Although the Democrat was the Condorcet winner (a majority of voters preferred him in all two way contests), he received the fewest first-place votes and so was eliminated ... 2009 mayoral election in Burlington, VT, which illustrates the key features of an upward monotonicity failure
Montroll was favored over Republican Kurt Wright 56% to 44% ... and over Progressive Bob Kiss 54% to 46% ... In other words, in voting terminology, Montroll was a 'beats-all winner,' also called a 'Condorcet winner' ... However, in the IRV election, Montroll came in third! ... voters preferred Montroll over every other candidate ... Montroll is the most-approved
a majority of voters liked the centrist candidate Montroll better than Kiss, and a majority of voters liked Montroll better than Wright ... yet Montroll was tossed in the first round.
K was elected even though M was a clear Condorcet winner and W was a clear Plurality winner.
We waited to bring in the signatures because we didn't want this to be about Kurt Wright losing after being ahead, or Andy Montroll who had more first and second place votes and didn't win. We wanted this to be about IRV.
