Term plurality rule Definition: A voting rule in which decisions are made based on a plurality of the votes cast. A plurality is defined as the most votes obtained when more than two candidates or options exist, but none receives a majority. If, for example, two of three candidates running for office receive 33 percent of the vote, then the third candidate with 34 percent receives the plurality.
