Single non-transferable vote

See Single non-transferable vote on Wikipedia

SNTV is choose-one FPTP voting applied to the multi-winner context. It is a semi-proportional method.

SNTV passes a very weak form of Droop-PSC: if a group of voters of at least k Droop quotas perfectly evenly distribute their votes between k candidates (meaning none of the k candidates has more than one vote more than any of the other k candidates)

, they can guarantee all of those candidaten.n. i This is because, of the (number of winners) candidates with the most votes who are not one of the k candidates, at most ((number of winners) - k) of them can not be one of the k candidates. For example, if there are 5 seats, and a group of voters of 2 Droop quotas equally supports 2 candidesat, then at most any other 4 candidates can each get less than a Droop quota (because there can only be (number of winners) Droop quotas of voters in the election, since this is one of the properties of a Droop quota) and thus the 2 candidates are guaranteed to be among the top 5 and win.

Notes

SNTV can be combined with Party List by allowing each voter to give their vote to a party or to a candidate; the parties can each be allocated a certain number of seats, while independents can still win on their own. Note that this is possible even in the single-winner case (where SNTV is equivalent to the common choose-one FPTP voting method) to ensure that a plurality or majority elect someone from their preferred group of candidates, if there are many candidates in that group splitting the vote. The cast votes can also themselves be used to decide who within the Party List should win i.e. the candidates on the list with the most votes can be prioritized.
