The Way We Vote
Wednesday, March 18th, 2009
As mentioned here the other day (What the People Said, March 5), Instant Runoff Voting (IRV) ”worked” in Burlington March 3 because the results showed that Mayor Bob Kiss, who won, would have beaten Republican Kurt Wright in a non-instant runoff, the kind that would have been held a week or two later and cost more money.
But it turns out that Democrat Andy Montroll would have beaten Wright one-on-one, also. In fact, an examination of the results indicates that Montroll would have beaten the Progressive Party’s Kiss as well.
And there is at least a plausible mathematical/political case to be made that if Burlington had been using a more traditional, two-stage election system, Montroll might have been in that final round.
No voting system is, not even the straight-up , most-votes-wins system, used in most of the country. In the United State House of Representatives, for instance the Democrats now hold (as did the Republicans throughout most of the last decade) a much larger majority of seats than the party’s share of the popular vote. So a “majority (or plurality) rules” system does not always reflect the actual majority of the people.
But IRV is more controversial. (It is, for those who have not been paying attention, a system in which voters rank candidates in an order of preference, and if no candidate is the first preference of a majority, the bottom contenders are eliminated and their ballots redistributed to the remaining candidates according to the next ranking on each ballot, until one candidate gets a majority)
Almost two weeks after the Burlington election, advocates and opponents of the voting system are still turning the blogosphere blue with acrimonious debates which range from abstruse mathematical formulations to personal attacks which occasionally rise to the level of, “yah mudda wears army boots.”
Inside baseball, yes. But that doesn’t make it unimportant. This is an argument over how public officials are elected. Considering that one side in this debate wants Vermont’s governor to be elected though an IRV system, somebody ought to pay attention.
This effort to pay attention will avoid all references to the footwear orientation of anybody’s parent, and will delve into the mathematical minutia only enough to demonstrate that IRV has its problems.
That’s because neither the personal squabbling nor the math is at the center of the dispute. Politics is. The IRV debate is hostage to competing visions – mostly but not entirely on the left side of the spectrum – of political strategy and behavior.
But let’s start with one bit of math, to wit, with monotonicity.
With what?
It means that candidate A should not rank lower in the vote count if he gets more votes. If that happens to candidate A, non-monotonicity prevails. That’s a flaw in the system.
That’s what happened. According to perhaps the calmest assessment of the vote, by pro-IRV analyst Wes Hamilton of Middlesex (writing as wdh3 on the Integral Psychosis web site), “Kiss won, but if 753 Wright voters had instead voted for Kiss, then Kiss would have lost…”
In other words, Kiss might have lost had he received more votes.
(Confused? For details, see Hamilton’s full article).
This does not mean that IRV is a bad system. It has its advantages. It’s cheaper than a separate run-off. It renders personal attacks risky (if you enrage the supporters of another candidate, they’re less likely to rank you second or third). It eliminates the danger, in a straight plurality election, that a candidate most voters really don’t support (Wright, in this case) could get elected.
Furthermore, non-monotonicity is a danger in regular run-offs, also. But a smaller danger. In a standard runoff, the voters know who the two front-runners will be before making their final choice. In IRV, they’re guessing. (On the other hand, turnout usually falls off for the run-off election, a disadvantage IRV avoids).
And IRV has other problems. University of Vermont political science professor Anthony Gierzynski said that one of them is that it “discriminates against classes of voters by adding complexity the ballot.” Poorer and less educated voters, Gierzynski said, are more likely to be confused by this complexity.
Not so, said pro-IRV Progressive activist Terry Bouricious (pictured above right), a former Progressive Party Burlington City Council member and state representative, who pointed out that ”voters in the low-income renter wards were as likely to use additional rankings as voters in the more affluent wards…There is no evidence of any class bias in the actual use of ranked-ballots.”
But this is inferring individual behavior from aggregates, a social science no-no. There are well-educated, affluent folks in those neighborhoods.
Not that there is conclusive evidence that Gierzynski is right, either. There simply haven’t been enough IRV elections to make that determination. But there is ample circumstantial evidence that IRV can be confusing, and obviously more confusing to the less educated. In support of this contention, allow me to present Exhibit A: Me.
I took me weeks of reading and interviewing to figure out exactly how IRV works. And I have covered some or all of 11 presidential elections, statewide races in 49 states (never got to Hawaii) and mayoral contests in every big city in the country. Granted, some will point out a paucity of intellect as a complicating factor here. But all that experience ought to mitigate that defect at least to some extent. So if IRV confused me, it’s likely to have confused others.
Again, all voting systems have their drawbacks and IRV has it advantages. But regarding it as the cure-all for electoral problems seems premature at best. Bizarre outcomes are as possible under IRV as under any other system. The Burlington election may have been an example of that.
In a sense, though, the technical back-and-forth about the pluses and minuses of IRV misses the main point. As both Gierzynski and Bouricious acknowledge, the dispute is really about political philosophy.
Gierzynski’s preferred remedy is not so much a different election system as a different political culture, in which those with “a (mostly) shared ideology,”( in Vermont, that means Democrats and Progressives) coalesced in one party, fighting out their differences in primaries before presenting a unified front in the general election.
Bouricious thinks that’s a bad idea. He derides that as a “political duopoly,” and prefers a multi-party setup such as prevails, he said, “in almost all the other democracies” in the world.
Well, not all. Britain has what is basically a two-party system; the third party Liberal Democrats are weak and likely to get weaker now that both major parties have moved to the center. Its de facto two-party system provides stability, in contrast to the multi-party Italian situation in which governments are lucky to last a year. Or the Israeli situation in which the minority (and in at least one case corrupt) ultra-religious parties exercise disproportionate power.
Besides, in most multi-party democracies, there are effectively two parties, as the several parties coalesce into two competing blocs.
“They do it after the election,” Gierzynski said. “Typically here in the U.S. we do it before the election so voters can see. We get to choose in our elections which coalition is going to run the government. They (voters in multi-party democracies) have no control over the coalition-building. It’s done behind closed doors.”
But to the many Vermonters who take a different point of view, IRV has another advantage. It protects a minor party such as the Progressives (I know, legally it’s a “major party.” But it isn’t) from being labeled a “spoiler” by taking enough votes from their sort-of allies, the Democrats, to throw a race to the Republicans. That’s what happened in 2002 when Progressive Anthony Pollina diverted enough votes from Democrat Peter Shumlin to elect Republican Brian Dubie.
In other words, whatever its advantages, in this state IRV is among other things a Progressive Party Preservation Act. Whether that’s a plus or minus depends on whether one thinks Vermont is best served by two major-party coalitions or by several independent parties, a matter over which reasonable people may differ. And do.
