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 (American literature)
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.
