It’s a novice system when it comes to real-world elections, where ranked choice voting is a battle-tested pro.
Seattle voters will decide in November whether to adopt approval voting, ranked choice voting, or no change to their primary election ballots. What do the research literature and practical experience say about these two alternatives to pick-one voting? They say a tremendous amount about ranked choice voting (RCV), and Sightline has summarized the lessons in tens of thousands of mostly encouraging words over years. But they say much less about approval voting (AV). This article summarizes what’s known.
Approval voting has intriguing features. It is simple to implement and easy to tabulate. Its proponents plausibly claim worthy benefits, including more moderate victors and less negative campaigning. It is worth experimenting with and deserving of study. We stand to learn more over time because two communities have recently adopted it. They are, in effect, conducting the clinical trials for this new voting method.
Both intuition and theory say AV will elect people who are, if not necessarily voters’ favorites, at least unobjectionable to most. They would be “consensus-style candidates,” say AV proponents. That tendency to dampen extremism and reward competent, cooperative governance, I surmise, is a major appeal of AV for its proponents and financiers, and it’s a goal Sightline shares.
But adopting AV for primary elections for all city offices in Cascadia’s largest city would be risky. For all its appeal, AV is a novel, unproven, and legally untested system for elections, and it has weaknesses that should give us pause.
The most salient fact about approval voting is that we do not actually know much about how it operates in the real world, not just in simulations or in academic papers or in the minds of schemers on Twitter or Reddit but in the pressure cooker of actual government elections, where campaigns rage, TV ads promise and malign, tempers flare, and hopes soar. This is where voters face the unavoidable dilemma into which AV forces them—that is, between helping their favorite and guarding against their least favorite.
We do not know if AV will deliver what it promises (moderation and a dampening of extremes), but we have reasons for doubt. We do not know if AV will lead to fair representation or pass court muster, but we have cause for caution. For these reasons, adopting it in Seattle in November would be risky, especially when Seattle can adopt the well vetted and helpful alternative of ranked choice voting instead. Let’s take a closer look at why.
1. APPROVAL VOTING IS TOO BASIC TO REPRESENT A VOTER’S PREFERENCES
Let’s start with the voter’s experience.
For voters, approval voting, like ranked choice voting, is an alternative to old-fashioned, pick-one voting. In it, you can fill in the bubbles next to as many candidates as you like. Whichever candidate gets the most approval votes wins.
It seems simple, and simplicity is appealing. AV is easy to understand and easy to tabulate. Unfortunately, its simplicity also holds weakness. Indeed, simplicity can make approval voting frustrating for voters.
The defining feature of approval voting is that it’s binary: approve or not, bubble filled or blank, yes or no. You approve just your favorite. Or your favorite and your second favorite. Or your top three. Or any number you choose. It’s up to you. Simple.
What you cannot do is convey any other preferences. No rankings. No ratings. No way to say that you love Nader but would settle for Gore, that you’d really like Perot but could live with Bush Sr., that you’d be elated with Biden, could get excited about Klobuchar, would be satisfied with Booker, and could tolerate Mayor Pete.
If your preferences are black and white, with no shades of gray, AV may be for you. Otherwise, the more you think about it, the more confounding it becomes. If you actually care who you vote for, you have no good option. Approve Elizabeth Warre...
