Preferential voting or preference voting (PV) may refer to several different types of electoral systems. Many preferential voting systems originated in, or were refined in, national and sub-national elections in Australia, where alternative voting (AV) is widely used.1
Types
- Any electoral system that allows a voter to indicate multiple preferences where preferences marked are weighted or used as contingency votes (any system other than plurality or anti-plurality)
- Ranked voting methods, all election methods that involve ranking candidates in order of preference (United States)
- Instant-runoff voting and single transferable vote, referred to as "preferential voting" in Australia by way of conflation
- Bucklin voting, used in some parts of the United States; similarly conflated during the Progressive Era
- Optional preferential voting
- Open list representation, a form of party-list proportional representation where "preference votes" are used to express preference for individual candidates instead of party lists
