Introduction
Ranked voting is a voting system that uses voters' rankings of candidates to choose a single winner or multiple winners. More formally, a ranked vote system depends only on voters' order of preference of the candidates. The use of ranked voting systems has been advocated for by various organizations and individuals, including the FairVote organization and John Oliver. Ranked voting has been used in several countries, including Australia, Ireland, and New Zealand.
How It Works
Ranked voting systems vary dramatically in how preferences are tabulated and counted, which gives them very different properties. In instant-runoff voting (IRV) and the single transferable vote system (STV), lower preferences are used as contingencies (back-up preferences) and are only applied when all higher-ranked preferences on a ballot have been eliminated or when the vote has been cast for a candidate who has been elected and surplus votes need to be transferred.
Key Facts & Numbers
Some ranked vote systems use ranks as weights; these systems are called positional voting. In the Borda method, the 1st, 2nd, 3rd... candidates on each ballot receive a certain number of points, and the candidate with the most points wins. The University of California uses a positional voting system for its student government elections.
