== Activism around FPTP ==
Much electoral activism has centered around providing alternatives to FPTP voting.
== As a multi-winner method ==
FPTP can be extended to the multi-winner case either as [[
While the [[single non-transferable vote]] is not in itself a proportional method, coordinated strategy by parties can make it behave like party list, which is proportional. However, the strategy needs to be carefully executed, and thus SNTV may encourage patron-client relationships in which a powerful legislator can apportion votes to his or her supporters.
== Notes ==
Line 22 ⟶ 27:
In the single-winner context, Approval is almost a [[Pareto criterion|Pareto]] improvement (pun) over FPTP; it preserves its simplicity and good qualities while adding in others, such as passing [[Favorite Betrayal]]. In the multiwinner context, [[SNTV]] is more proportional than [[Bloc vote|Bloc Approval voting]], so a [[Cardinal PR]] method using Approval ballots may work better.
▲FPTP can be extended to the multi-winner case either as [[SNTV]] or [[Plurality-at-large voting]]. An in-between form is limited voting, which gives a voter the ability to choose fewer candidates than the number of seats to be filled, but usually lets voters pick more than one candidate. The general principle in any multi-winner extension of FPTP is that a voter can support at most as many candidates as there are seats to be filled.
One of the biggest complaints against FPTP is that it has a [[spoiler effect]]. This is most easily visualized by observing that FPTP passes the [[majority criterion]] but not the [[mutual majority criterion]]:
Line 44 ⟶ 47:
Note that [[Asset voting]] can be thought of as a way to modify FPTP to better reflect voters' wishes, because it allows voters who are unrepresented by the FPTP winner to form majority coalitions for their preferred candidate among the losers. In effect, instead of voters being forced to group behind only two candidates whatsoever, Asset allows voters to do this, and then if they dislike the winner of the top two, they can recombine behind other candidates in new [[Head-to-head matchup]]<nowiki/>s.
