=== '''Vote unitarity''' ===
One generalization of the Equally Weighted Vote for the multi-winner or proportional context is [[Vote unitarity|vote unitarity]]. ThereThe is some controversy over whether or how relevant it is in that context, but thebasic idea is that when a voter is "maximally satisfied" with one representative (they gave one of the winners a perfect score), theyvote should notstay haveequally anyweighted influence on selectingthroughout the otherelection winnerstabulation. NoteA thatvoters thereinfluence areon nuanceselecting to this; if, say, every voter gives one of thesubsequent winners ashould perfectdirectly score, then instead of everyone's vote having no influencedepend on the other winners, vote unitarity tries to ensure some kindamount of proportionalsupport decreasethey ingave voting power such that every voter still has a significant amount of influence on thefor remainingprior winners.

There is an important nuance to this with regards to [[Surplus Handling]]; if, say, every voter gives one of the winners a perfect score, then instead of everyone's vote having no influence on the other winners, vote unitarity tries to ensure some kind of proportional decrease in voting power such that every voter still has a the correct amount of influence on the remaining winners. The simplest implementation of this is with [[Sequentially Spent Score]].
 
 
In summary, there is a proportional relationship between how much support the voters give to the winners and the amount of influence that is removed from the voters, to ensure that every voter has a chance to fairly elect someone they prefer. The prominent [[Reweighted Range Voting]] method fails vote unitarity.
