Runoff voting

From Wikipedia, the free encyclopedia
(Redirected from Run-off vote)

Runoff voting can refer to:

  • Sequential-loser methods based on plurality (comparison of votes tallies) and eliminations:
    • Two-round system, a voting system where only the top two candidates from the first round continue to the second round.
    • Instant-runoff voting, an electoral system where votes rank candidates and if necessary last-place candidates are eliminated one by one until one candidate has a majority of votes.
    • Contingent vote, a preferential ballot version of the two-round system.
    • Exhaustive ballot, an iterated voting system where if necessary, numerous rounds of voting are held sequentially. Last-place candidates are eliminated one by one until a round of voting sees a candidate receive a majority of votes.
