While some jurisdictions had off-year elections yesterday, four others voted on instant runoff voting (aka IRV, alternative vote, single transferable vote applied to a single-winner election). Three others used IRV for public elections, and one other used STV (aka choice voting), crème de la crème of candidate-based, multi-winner methods.
On implementation/retention
In Pierce County, WA, IRV survived a veritable repeal attempt 66% to 34% just one year after its passage. Charter Amendment 4 would have restored the closed primary and delayed implementation until 2010.
Sarasota, FL voters passed IRV 78% to 12%. Implementation is pending compatible equipment at the county level.
In Aspen, CO, 77% approved IRV for mayor and a “multi-seat” variant for two at-large council seats. This was an advisory referendum.
In Clallam County, WA, IRV failed 55% to 45%.
Overall good news for the reform movement, which passed IRV and/or STV in four jurisdictions last November.
In public elections
Hendersonville, NC used “multi-seat” IRV for the first time.
Takoma Park, MD used IRV city-wide for the first time. Some voters had a first exposure last January in a special vacancy election. Takoma Park passed IRV in November 2005.
Once again, San Francisco voters ranked up to three choices on optically scanned IRV ballots. It passed there in 2002.
Finally, Cambridge, MA used STV to elect nine city council members and six school committee members. The quota: Droop. The surplus transfer: Cincinnati method. The count: electronic. (Yes, electronic. And surplus transfer might be fractional if not for politics over voting equipment and the city’s grandfathering post-statewide repeal.)
Cambridge has used STV since 1941. It’s the lone survivor of 24 (some say 22 or 23) Progressive Era municipal implementations, the rest of which faced racially and politically charged repeals through the 1950s. (However the NYC school board lasted until 2002). Cambridge itself survived several repeal attempts.
