The troubling rise of Prime Minister Boris Johnson in the United Kingdom and President Donald Trump in the United States can both be traced to the inherent problems of geographically based electoral districts.

Before Alberta’s election in April, we had a chance to fix those flaws. Instead, the work of the 2016-2017 Alberta Electoral Boundaries Commission resulted in a new electoral map that was deeply flawed, created by a flawed process and based on flawed assumptions.

Our system of geography based electoral districts has deep roots that go back centuries in the United Kingdom. At their inception, geographically delineated constituencies were not created for the purpose of democracy, but rather as an expression of the power of aristocrats.

In essence, MLAs are philosophically the inheritors of archaic systems designed for Henry III’s barons in the 1200s.

Later legislation (such as the Reform Act of 1832) may have added democratic apparatus to constituencies, but the idea of a geographic constituency was fundamentally not designed to advance the representation of voters. As a metaphor, you might add an outboard motor to a bathtub, and it’ll get you across a lake, but the tub is ill suited to that task.

The first advent of democratically elected representatives of geographic constituencies occurred in a low-data world that is entirely unlike the information-rich environment in which our current policy makers operate. This meant that while 18th Century MP Robert Walpole, regarded as the first prime minister of Britain, may have known roughly whether the average person in his district of Castle Rising was wealthy or poor, it was very rudimentary knowledge compared to the household-by-household and street-by-street data available to modern election campaigns and to map designers.

We’ve seen in recent years how a corrupt redistricting process can make use of this kind of data. North Carolina’s congressional map comes to mind. A Republican-controlled process devised and implemented a congressional map that concentrated Democratic voters in three districts and allowed a statewide minority of Republican voters to win the other 10.

It is one of the finest examples of Gerrymandering – designing a map to favour one party – and would have been impossible to accomplish in earlier decades due to the paucity of granular data about voters.

There is, however, an upside to this data-rich environment: when implemented correctly, this information could be used to mitigate the anti-democratic underpinnings of geography based representation.

Historically, Alberta has largely avoided the worst pitfalls of redistricting. We have yet to see overtly partisan gerrymandering – though some of the low-population northern ridings have sometimes borne a significant similarity to the ‘rotten boroughs’ that once infested the British Parliament.

Premier Rachel Notley’s appointment of a panel composed of representatives of both major parties to oversee this electoral boundary review fit well into the provincial tradition. But the terms of reference for the committee had the same problems that every previous redistricting had since the dawn of our electoral district system: the wrong priorities, inappropriate skill-sets, and blindness to the structural issues inherent in geography based electoral districts.

Consider the commission’s priorities. As per constitutional precedent, and as per the Supreme Court case Reference re Prov. Electoral Boundaries (Sask.), [1991], they set out with the noble goal of ensuring “effective representation.” But while effective representation sounds high-minded, all it really means is that there should be a similar number of voters in any electoral district, and that there are no obvious impediments to them addressing concerns of any particularly remote group of voters.

There is, essentially, no real way to measure how “effective” a representative is, and we are left with the most reductive interpretation of this ruling.

Elbridge Gerry, for whom the term gerrymandering is named, also refused to sign the U.S. Constitution because it didn’t abolish slavery. So the guy wasn’t all bad! (Image: Public Domain).

The second priority for electoral boundary commissions has been more problematic: To adjust the population size of districts while keeping most boundaries as static as possible. In fact, during the public hearings of the Alberta Electoral Boundaries Commission, one question was asked of almost every member of the public who attended: “Which boundary of your home riding would you change to address population growth, while leaving the rest unchanged?”

There is little reason to think keeping district boundaries as static as possible does anything to advance democratic aims. In fact, boundaries that change little over time may only serve to entrench incumbents.

Elected officials seeking re-election already enjoy a strong advantage – approximately 10 per cent, according to some estimates. Incumbents who have that kind of head start, often guaranteed re-election regardless of the work they do, are less likely to feel the need to work hard representing their constituents. In other words, perpetuating the incumbency advantage leads to less effective representation.

In the United States, constituencies that have a high partisan lean – that is, they are “safe” for one party or another – tend to be represented by the most radical wing of that party. Because their elected representative is most vulnerable to an intra-party challenger, they are incentivized to avoid cooperation or collaboration with people from across the aisle. This leads inevitably to gridlock and bad policy.

It could be argued this dynamic also contributed to Brexit, Boris Johnson, and the ongoing breakdown of government in the United Kingdom.

So how should a boundary commission go about redrawing an electoral map?

The answer is “mathematically.”

The gap in vote efficiency is one effective measurement that needs to be considered in this redistricting process. If the voters of one party are packed into a given district, then all votes beyond the 50 per cent needed to win that district are “wasted,” as are all votes that are cast for a losing candidate.

Comparing the percentage of all votes for each party that are “wasted” provides one measurement of how advantageous a riding map is. In the last election, the efficiency gap between the NDP and the UCP was 6.25 per cent in favour of the UCP.

Now, every map will inherently have a partisan lean. It’s inescapable in part because of the way groups of voters tend to cluster together. Nowadays, left-leaning people tend to congregate in cities; rural areas tend to be more conservative. This clustering means that votes will be wasted.

Although it’s difficult to be certain, the partisan lean of Alberta’s map does not appear to be egregious by the standards of other jurisdictions. This is, however, faint praise.

To determine if a map’s partisan lean is excessive, mathematicians Alan Frieze, Wesley Pegden and Maria Chikina proposed an ingenious solution: Create thousands of randomly varied maps and measure the partisan lean of each variation. If the partisan lean of the actual map is greater than that of the majority of these random districtings, then the map should be redrawn.

Such a method can be used to find optimized solutions for a number of metrics. You can develop maps that have ridings whose makeup best represents the overall population on demographic measurements like ethnicity, age, and income. You can create a map that prioritizes having a representative sampling of left-handed people versus right-handed people. But the metric that will probably lead to the best outcomes for voters is one that elected representatives will not like: largest number of competitive districts.

Competitive districts lead to representatives that have to work to earn the votes of their constituents. In Alberta, more competitive maps would make the phenomenon of the MIA MLA less prevalent. It would also mean that strong partisan bias for an individual elected official would be a losing strategy, since they would be more worried about the general election than getting re-nominated.

It’s worth noting that in its final report, Alberta’s recent electoral boundary commission made no mention of such metrics. And those omissions make sense – the commission was made up mostly of lawyers and led by a judge, Justice Myra Bielby of the Alberta Court of Appeal. Lawyers can be counted on to ask lawyerly questions, and interpret terms of reference carefully, but with a narrow and limited perspective.

To be effective in the 21st Century, an electoral commission needs at least one person with an advanced degree in mathematics, preferably someone who has studied topology or global optimization. It would also be appropriate to include an economist, preferably one with a background in game theory. Individuals who have studied geography and sociology could also provide important perspectives. The key questions surrounding modern electoral maps have less to do with the law than they have to do with these other disciplines.

The terms of reference and appointment process of the 2016-2017 panel were in line with past practice. But these terms of reference were insufficient. Geography based electoral districts with a first-past-the-post system are a bad way to divide people for the purposes of political representation. The terms of reference could have tasked the commission with creating boundaries that mitigate the flaws inherent in the fact that we divide voters up by where they live.

Our adherence to this antiquated system – which we inherited from the United Kingdom without ever asking if it was the best for governance – is based on anti-democratic assumptions that may have been blunted over the centuries, but whose influence is still felt.

As long as we are stuck with this system, we should work to subvert its biases, and the best tools we have to do so are complex mathematical models.

We need election commissions that include the skills to do so, and have a mandate that empowers them.

    Very refreshing perspective!
    Our democratic experiment is at risk as never before. Not least because of moribund and decrepit procedures and institutions.
    The twin ideas that each eligible voter should have say in civil developments and decisions and that all actors in society follow the same set of rules are truly unique in the long history of mankind. These ideals must be preserved but the methods, the traditions and the trappings should be let go as soon as they no longer serve.
    Our archaic electoral system no longer serves the population; it seems to provide an extravagant lifestyle for a very few while serving and supporting the most corrupt and shady interests of foreign corporations.
    Is it any wonder that most people don’t participate?

    And surprise! surprise! The new citizens of the 21rst century have less and less attachment to this electoral system that we are passing along. No one should be surprised that they are in the process of discarding it entirely in favour of something new.

    “Information rich?” Really? Most people are either so busy making a living they have no time to gather information or they are ‘entertaining themselves to death.’ This should be no surprise since our geographically based political system has spent the last 40 years impoverishing people by chipping away at the legitimacy of community, democracy, and our legal system in the service of the aristocrats of globalization. Alberta is just a little late to the game, but we are catching up. Look at how the UCP crippled our medical diagnostic system by destroying the bio-med lab in Edmonton so we will be forced to pay the oligarchs for those services.

      KANG you are absolutely correct about UCP crippling our medical diagnostics system. My daughter went to university both in Alberta and England in tropical and infectious disease and worked for London Health as well as Alberta Health in research. England tried the same thing as UCP is doing in Alberta privatizing medical diagnostics. The problem they found in England by privatizing the diagnostic system the private sector under reported everything and researchers were left trying to analyze and determine, for example, the strain of vaccine needed for next season’s flu viruses, which made it difficult because of private sector limited information provided. England went back to Government being in control of infectious disease and the reporting system improved significantly. When it comes to Health the private sector is more interested in profits and that is why they contribute to political parties that will support and give them government contracts. Most people do not understand how the private health system operates, one just needs to look at the Pharmaceutical Drug system, and this is why there are so many issues when it comes to private health. And for government to put pressure on the private health system to report what does one think will happen to that political parties funding.

    The term “represent” is most problematic—right up there with “democratic principles.” To some it means actually advocating government policies the majority of constituents want. Well, a candidate might promise such, even get up and say so in parliament but, in fact it’s much simpler than that: “representative” ultimately means the elected person from a particular electoral district whose purpose is to approve or not the budget presented by cabinet, not necessarily to represent anybody. That is, he or she “represents” every single resident in the riding by casting the parliamentary vote, yea or nay (or, sometimes, abstaining) whether the views or each and every resident is in agreement or not.

    Representation rather depends on how the whole electoral slate panned out and which group of parliamentarians is recognized government, which Loyal Opposition, and which form the remainder, a dampening of any measure of constituent agreement in any particular riding—which, possibly because of bent districting, might be very much or not at all.

    The various electoral boundary commissions with which I’ve corresponded in BC have asked citizens the questions most of us feel are important, from where one works to where one shops —and of course where one votes—even how one votes.

    But, like so much of politics these days, citizens are missing in action during some of the most important exercises of democracy, most especially (if we put aside actually running for office) in belonging to a political party; but corresponding with electoral boundary commissions is another for which citizens don’t make much time, for whatever reason. At least we know why resorting to jurisprudence, an fundament of democracy, is generally not availed: it’s way too expensive and slow.

    Great article. Thnx!

    Setting electoral boundaries to create the most competitive districts would, if we base it only on the April 2019 election, produce a hugely distorted map, with far more seats in Edmonton than can be justified by its population, and very few seats outside the two big cities, where the UCP had both a large absolute majority in the popular vote and in each seat.

    For instance, the largest turnout was in my own constituency, Grande Prairie-Wapiti, at 80.4% (this in a riding the hadn’t reached 50% turnout in the previous three elections), and the UCP candidate, Travis Toews—now, unfortunately, our Minister of Finance—got 74.2% of the votes cast: essentially, 3 in 4. This was a far from competitive riding, and the other Peace Country ridings were similarly uncompetitive. Would that mean that we only get one MLA for our vast area?
