Potential collision of “voter choice” and “majority rule”

Tomorrow is the in-person primary election in New York City. Polls variously expect Andrew Cuomo and Zohran Mamdani to win the Democratic mayoral nomination. In the background, the city’s charter commission is considering an overhaul of the mayoral electoral system. TLDR: one proposal would mandate two-candidate general elections.

We will see what happens in the primary. I wrote about the situation here.

For me, this episode underscores a tension in the world of electoral reform. On the one hand, many of these devices promise “majority rule.” On the other, they promise to make it easier to run for office without expectation of majority support. Some are drawn by the former idea, others by the latter.

If you are looking for a term to describe the form of RCV that the situation might bring forth, one option is “bottoms-up.” I wrote about it in this 2021 journal article.


Report on Portland’s first STV election

I have a new report with Kevin Kosar and Jaehun Lee of the American Enterprise Institute:

Key Points 

  • Portland, Oregon, used its decennial charter revision process to overhaul its method for electing the city’s legislators in 2022. 
  • The new system divided the city into four districts, with each district represented by three members selected through ranked ballots. 
  • Portland first used this new system in November 2024, and initial analysis indicates that it expanded the representativeness of the candidate pool and resultant council.

Block-preferential (or sequential) RCV is out in Heber City, UT

The local Park Record has a story here.

Here is a 2023 blog post on a “downward cascade” process in that year’s election results.

I wrote about this system in a 2021 article, which also covered its historical use in Australia and similar rules at other times in the U.S.

McCune et al. (2024) have an interesting article using the block-preferential (or “sequential”) procedure to show how it would change observed results under Scottish STV.

One alternative to outright repeal would be to replace the system with a “bottom-up” RCV allocation. The issue in Utah has been multiseat districts, which formerly were combined with runoffs.
