In [[Multi-Member System|sequential multi-member methods]] this concept become especially relevant due to the different rounds of tabulation. Specifically, a voter whose favorite has been elected should not have influence over subsequent rounds. On the other side, a voter who has not been fully statisfied should still have some level of influence. This means that systems which allocate votes such as [[Single transferable vote]] and [[Sequential Monroe]] violate vote unitarity if they allocate the whole vote weight to a candidate the voter did not express maximal endorsement for. In [[Ordinal systems]] it is not possible to know how much influence should be lost at each round since only relative endorsement is given. In [[Cardinal voting systems]] the influence of each voter in each round goes down proportionally in relation to the amount of representation they have won in previous rounds. |
