The '''Coombs' method''', created by [[Clyde Coombs]], is a [[voting system]] used for single-winner [[election]]s [[preferential voting|in which each voter rank-orders the candidates]]. It sortis ofvery workssimilar liketo [[Instant Runoff Voting]] (a US term; it is known as Preferential Voting in some other countries) in reverse.

==Procedures==

Each voter rank-orders all of the candidates on their ballot. If at any time one candidate is ranked first (among non-eliminated candidates) by an absolute majority of the voters, then this is the winner. As long as this is not the case, the candidate which is ranked last (again among non-eliminated candidates) by the most (or a [[plurality]] of) voters is eliminated. (Conversely, in [[Instant Runoff Voting]] the candidate ranked first (among non-eliminated candidates) by the least amount of voters is eliminated.)
