Instant-runoff elections produce a lot of data about voter preferences. Typically, this information is made available by election boards in specialized file formats and requires processing to interpret. The purpose of rcv.report is to increase transparency into these elections by creating detailed and intuitive reports about them.

All reports are generated from the raw ballot data, rather than using the official tabulation. As a result, the reports also serve as an independent tabulation of the results that can be reproduced using published source code.

Featured Elections

We feature elections where the ranked-choice voting process was meaningful—specifically, races that required three or more rounds of tabulation. Elections decided in one or two rounds are excluded because they represent cases where a candidate won with a clear majority from the start, making the instant-runoff mechanism less relevant. By focusing on elections with multiple rounds of elimination and vote transfers, we highlight cases where ranked-choice voting had a substantial impact on determining the winner.

rcv.report is a fork of ranked.vote which was created by Paul Butler. rcv.report is maintained by Felix Sargent. It is non-partisan and has received no outside funding.

If you enjoy alternate voting systems, you may also enjoy approval.vote, which is a similar project for approval voting elections.
