Abstract

This note supplements the recent work of McCune and Wilson (Public Choice 196(1–2):19–50, 2023) by providing a complete analysis of spoiler effects under both plurality voting and Ranked-Choice Voting in the case of three (potential) candidates. The trick for definitively identifying all spoiler possibilities under both voting rules in the three-candidate case is to partition the set of all three-candidate preference profiles into eight types by cross-classifying the candidates in terms of their plurality status and Condorcet relationships. The resulting typology allows us to identify the winners in all possible two-candidate and three-candidate elections under both voting rules and therefore suffices to identify all spoiler effects. It implies, among other things, that the set of profiles that are vulnerable to spoilers under Ranked-Choice Voting is a proper subset of those vulnerable to spoilers under plurality rule.
