Single transferable vote: Difference between revisions

 

STV passes [[PSC]] regardless of the method used to decide which candidate is to be eliminated next, because for a solid coalition comprising k quotas, once all but k of the candidates in the coalition are eliminated, at least one of the k remaining candidates will have a quota of 1st choices and win, with their surplus transferring if necessary such that another of the k candidates wins, etc. It passes the [[Droop proportionality criterion]] when the [[Droop quota]] is used, making it one of the few commonly discussed PR methods that guarantees that a majority will always win at least half of the seats.

 

STV has several variations that can be discussed. For example, Meek and Warren STV are variants of STV that attempt to make the process fairer, but at the cost of needing to be computerized to compute the result.
