FairVote touted the 2009 election as one of its major success stories, with IRV helping the city avoid the cost of a traditional runoff election (which likely would not have changed who won). They also argued IRV prevented a
spoiler effect that would have occurred under
plurality. Later analyses stated the race was spoiled, however, with Wright acting as a spoiler pulling moderate votes from Montroll, who would have defeated Kiss in a one-on-one race. (However, when Montroll's votes were transferred, they went largely to Kiss, not to Wright.) FairVote also claimed the election as a success story because 99.9% of voters filled out at least one preference on their
ranked-choice ballot. 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). Several
electoral reform advocates branded the election a failure after Kiss was elected despite 54% of voters voting for Montroll over Kiss, violating the principle of
majority rule. ===
Tournament matrix === The results of every possible one-on-one election can be completed as follows: This leads to an overall preference ranking of: • Montroll – defeats all candidates below, including Kiss (4,064 to 3,476) • Kiss – defeats all candidates below, including Wright (4,313 to 4,061) • Wright – defeats all candidates below, including Smith (3,971 to 3,793) • Smith – defeats Simpson (5,570 to 721) and the write-in candidates 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.
Hypothetical results under various voting systems 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 if they voted again the same way that they marked their preferential ballot, he 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). Analyses suggested Montroll also would have won under most
rated voting methods, including
score voting,
approval voting,
majority judgment, or
STAR voting. == Effect on IRV in Burlington ==
