A first-preference is a voter's most-preferred candidate.[1][2][3][4] In certain ranked systems such as first preference plurality, ranked-choice voting (RCV), and the single transferable vote, first preferences for a candidate are considered most important and prioritized heavily. This incentivizes pandering to the political base or "core support" as a result of the center squeeze effect. Methods like Condorcet voting, rated voting, and the Borda count do not exhibit such effects. Methods like anti-plurality voting and Coombs' method have the opposite effect, being dominated by a voter's bottom rankings and so tending to elect the "least offensive" candidates.
First-preference votes are used by psephologists and the print and broadcast media to broadly describe the state of the parties at elections and the swing between elections.[4][5][6] The term is much-used in Australian politics, where ranked voting has been universal at federal, state, and local levels since the 1920s.
