Why do electoral reform advocates obsess about the 2009 mayoral race in Burlington, Vermont. This page discusses the reasons.

• Monotonicity - There are many people that obsess about the monotonicity criterion failure that happened in
• Condorcet criterion - this was the indisputable failure of instant-runoff voting in that election

The Condorcet criterion is not that hard to explain. In short, if a simple majority of voters prefer candidate A over candidate B (and express that preference on their ballots), then candidate B should not be elected.

As readers of Electowiki know, I'm Rob Lanphier, aka User:RobLa. I'm planning to iteratively publish an email interview with Robert Bristow-Johnson on this page. Robert is an electoral reform activist, and has been a longtime member of the Election-methods mailing list ("EM list"). Robert's first message in October 2009 (a response to Michael Rouse's "new method/request for voting paradoxes" thread), and he's been continuously active since then. In fact, recently, he engaged in a conversation with a conversation with Kristofer Munsterhjelm about "Linear summability" , which is what inspired me to start this interview.

The questions below will be from me, and answers will be from Robert.

Interview

Below is an interview with Robert Bristow-Johnson, conducted via email. Robert has lived in Burlington for a number of years, working in a variety of roles as an audio engineer, having written "The Audio-EQ Cookbook". Back in 2009, VahallaDSP had this to say about him:

If you program audio DSP effects, you have undoubtedly heard of Robert Bristow-Johnson. If you haven’t heard of him, get yourself a copy of his Audio-EQ Cookbook. This is a succinct little document, that provides coefficient generation formulas for pretty much any second order filter building block you would ever need: lowpass, highpass, allpass, peak EQ, notch, shelving filters, etc. Today, I am implementing these formulas for my own code, but I know I’ve implemented them in at least 3 prior DSP environments. Really good stuff. A quick Google search doesn’t turn up a ton on Robert Bristow-Johnson (or RBJ, as he is often abbreviated). He worked at Eventide, Fostex, Young Chang (Kurzweil), and Wave Mechanics. RBJ has a few AES papers as well, all of which are worth reading, covering topics ranging from PSOLA pitch shifting (made famous by AutoTune) to filter design to interpolation for oversampling.

Robert is a longtime citizen of Burlington, and has long been troubled by the persistent drive toward Instant-Runoff Voting (IRV) in Burlington. In 2014, he was invited to write "Having it Both Ways" for the local "VTDigger" publication from The Vermont Journalism Trust, where he pointed out a strategic mistake (or two, or maybe more) that the Republicans in Vermont made. I'm grateful for the opportunity to interview Robert via email:

Question #1: introduction

Q: (User:RobLa) - It's my understanding that you were living in Burlington back in 2009, when this election took place.  Is that correct?  If so, can you tell me what it was like?

A: (Robert) - My family and I moved to Burlington in 2000 and it was always my permanent address and voting address since 2000. I've voted in nearly every election there in the 21st century and have served as an election official in Ward 7 for three years. Ward 7 is where Bernie and Jane Sanders live. There's a photo of Bernie voting in Super Tuesday 2016 and me standing in the room that someone snapped offa the TV screen. I've done some other activism affecting Burlington elections in that I drew the map that was eventually adopted in defining Burlington's 8 wards.

Both Vermont as a state and particular towns like Burlington are pretty far left of center, in an authentic and wholesome way. Bernie Sanders, in becoming mayor back in the 1980s, essentially founded the nation's most successful third party (in terms of getting people elected to government), the Vermont Progressive Party. There are a lotta state legislators and city councilors with "P" after their name, yet Bernie never put a "P" after his name, nor a "D" until he ran for President in 2015. Instant-Runoff Voting (IRV) was happily adopted in 2005 and used first 2006. Now the label Ranked-Choice Voting (RCV) is used for the very same method as IRV, although it's a neologism and a misnomer. Ranked-Choice Voting originally means any election system using ranked-order ballots where voters mark their candidates #1, #2, #3...

In March 2009 (first Tuesday, what we Vermonters call "Town Meeting Day") Burlington held the second mayoral election using the "standard" Instant-Runoff Voting method of RCV. This election had 5 candidates on the ballot, 4 candidates were credible with a serious financial investment into publicity and promotion. Several candidate forums with all 4 candidates. Going into Town Meeting Day it was a toss-up between three candidates that were all plausible winners.

The result was that the Republican Kurt Wright had the plurality of first-choice votes, the Democrat Andy Montroll was the Condorcet winner (a.k.a. the "Pairwise Champion"), and the Progressive Bob Kiss, the incumbant, was the IRV winner and therefore was re-elected mayor of Burlington for another 3 years.

A lot of people expected Andy to win. He was the candidate in the center, had a lot of first-choice votes (but came in third) and far more second-choice votes than any other candidate. Almost immediately University of Vermont (UVM) Legislative Research Shop (led by Prof. Anthony Gierzynski) and outside analysts Warren Smith and Brian Olson examined the individual ballot data and reported that Andy Montroll was the Condorcet winner, the candidate who would beat any other candidate in the IRV final round, had Andy been in the final round.

Right away many people were suspect of the legitimacy of the election result and called for the repeal of IRV. That repeal effort was successful and Instant Runoff Voting was repealed the following year, at Town Meeting Day 2010 with a 4% margin of defeat. I voted to retain IRV, because it was better than First Past The Post (FPTP) and I had hoped that it could be reformed into a Condorcet-compliant RCV, but I was on the losing side.

Supporters of Kurt Wright, the plurality winner (of first-choice votes), thought he was robbed. A few people like me understood that it was Andy Montroll who was robbed. The Progs and the IRV happy talkers became entrenched and insisted that their candidate was legitimately re-elected (and he was, according to the law) and that nothing went wrong with the election but supporters of losing candidates were sore losers. But, just like the 2000 or 2016 presidential elections, in a democracy there is a real problem when the majority of voters are sore losers.

When I found out (from the news) that Andy was the pairwise champion, I obtained the same ballot data myself from the city clerk's office and wrote my own computer program to scan the ballot rankings and tally the election using Condorcet rules and confirmed the results although my numerical results are slightly different than either Warren Smith's or Brian Olson's numerical results. But the qualitative results, who beats whom, are exactly the same. The ballots I counted were exactly consistent with those counted in the IRV tally so my subtotals agree exactly with the official round-by-round tallies of the IRV election.

Question #2: knowledge of Condorcet

Q: (User:RobLa) - That's interesting! How did it occur to you to try tabulating the pairwise results? How well did you understand the Condorcet methods prior to the 2009 election?

A: (Robert) Well, it was because the local news reported, within a week or two, that in some sense Andy really won the election. How was that? And I knew that the only sense it could be was that Andy was the Condorcet winner (CW) and I knew that if the CW gets to the IRV final round, the CW will beat anyone there and win the IRV election. I knew who was, locally in Burlington, responsible for introducing IRV to Burlington, Terry Bouricius, who is, I believe, a member of the EM Mailing List because it was he that suggested that I join it. There were dueling commentaries in the local papers between Terry and UVM Prof. Anthony Gierzynski about whether something actually screwed up in the IRV election. It wasn't until I actually got on the EM list that I figured out who Warren Smith is and that it was Warren who was in command of the technical details and was actually the fact source behind Prof. Gierzynski. I didn't see Warren's page at https://www.rangevoting.org/Burlington.html until later but somehow found out that there was raw ballot data available from the Burlington City Clerk voting website burlingtonvotes.org .

Question #3: knowing about Condorcet before 2009

Q: (User:RobLa) - So you knew about Condorcet winners before the 2009 election? How well did you understand electoral methods before 2009?

A: (Robert) -
