Vote unitarity: Difference between revisions

Since [[Single Transferable Vote]] allocates voters it obeys vote unitarity. [[Reweighted Range Voting]] on the other hand only reduces influence fractionally so a voter who got a candidate they gave max score in the first round they ballot weight is reduced to 1/2. This violates the principle of one person one vote since this person would essentially be allowed to vote with half weight in later rounds. Proponents of [[Single Transferable Vote]] would use this argument for its superior fairness over [[Reweighted Range Voting]]. [[Keith Edmonds]] wanted to design a score reweighting system which was not simple allocation but also preserved the amount of score used through sequential rounds. He was also unhappy with [[Allocation systems | Allocated Score]] since somebody who only gave a score of 1 to the winner could lose all future influence. [[Single Transferable Vote]] is essentially an allocation system so it also has this failing. [[Sequentially Spent Score]] is the sequential [[Multi-Member System | Multi-Winner]] [[Cardinal voting systems | Cardinal voting system]] built on [[Score voting]] ballots to follow this principle.
