Rob Richie and Dorothy Scheeline of Fairvote have written some interesting analysis of last week’s elections that used instant runoff voting, aka ranked choice voting. Instant runoff voting was used in San Francisco, CA, St. Paul, MN, and Portland, ME; in all three cities, Greens both helped enact IRV and ran in last Tuesday’s elections. For the mayoral elections in Portland and San Francisco, Fairvote has graphs that show the breakdown of votes round by round until someone takes a majority (in Portland, Greens David Marshall and John Eder finished 4th and 12th of 15; in SF, Green Terry Baum finished 11th of 16). In a Huffington Post article, Richie and Scheeline focus on the story of IRV’s success in Portland:
Repeatedly, we are seeing RCV winners being the candidates who do a particularly effective job at reaching out to voters, often with direct contact involving community debates, local events, and door-knocking. One Portland candidate, David Marshall, said he knocked on 20,000 doors. He didn’t win, but it was ballots from his supporters that provided a particularly strong boost to the new mayor’s win total.
