Basic historic facts about ranked choice voting

Below are two key dates for anyone writing about “ranked choice” or “preferential” voting in US elections.

1909: first adoption of majoritarian form for public elections (Grand Junction, CO);

1915: first adoption of proportional form for public elections (Ashtabula, OH).

There was use of the majoritarian form in some party primaries, but I cannot find any evidence of this prior to the Grand Junction adoption.

And there was earlier use of the proportional form, around 1911 and/or 1912, in the single-tax colonies of Arden (DE) and Halidon (ME).

The motivation for this post is a recent article flagging the 1940s as the start of US experimentation with preferential voting rules. As far as I can tell, this information passed to the journalist from a political scientist.

Scholarly work on RCV

I have started a bibliography of recent, empirical, and peer-reviewed work on ranked-choice voting.

My hope is that the page will be useful to policymakers and researchers. So far, it covers burdens on voters, burdens on election officials, effects on candidates and parties, causes of adoption/repeal, and book-length historical accounts.

Please reach out if you have something to add.
