Is the single transferable vote a form of proportional representation? Right now I believe it is. A reviewer once said the fight had been won. Either way, this issue stops some of my talks dead in their tracks. Some are bothered that PR might coexist with candidate-based ballots.

The urban PR “spells” chart, updated
If you are reading this, you know that 24 U.S. cities tried the STV form of proportional representation. Here is an updated chart summarizing those episodes.
The changes include:
1) Cropping to 1965, since events thereafter are basically chartjunk.
2) Adding a failed 1959 repeal attempt for Worcester, MA.
3) Changing the dates for Oak Ridge, TN, which evidence suggests to have emerged with STV a decade later than I thought. Note that the Oak Ridge council was “advisory,” whatever that means.
4) Adding Norris, TN, which I had not included because I could not find the dates of any STV elections. This Town Council was also “advisory.” Elections were held annually from 1937 through 1945. I cannot find evidence of an STV election post-1945. The federal government sold Norris to a developer in 1948, and Tennessee granted Norris its own charter in 1949.
5) Date-stamping, since this chart may evolve gain.
Please share any suggested, further changes. Wouldn’t it be nice if our state and local politics were better documented?
STV is also totally compatible with polarization
On Friday, I showed NOMINATE scores for Cincinnati City Council members elected under permissive rules. Polarization was super low* for some years because, in each of those years, a lone wolf was able to play coalition kingmaker in a hung parliament.**
Now look at 1947, which is new in this plot, and watch those parties diverge. Yup. STV is totally compatible with high levels of polarization. (I never said it wasn’t.)
