Some critics of IRV misunderstand the tally to think that some voters get far more votes than other voters. In Ann Arbor, Michigan, for example, arguments over IRV in letters to newspapers included the belief that IRV "presents minority candidate voters two votes", simply because some voters' ballots may perhaps count for his or her initial choice in the very first spherical as well as a lesser selection in a very afterwards spherical.
The regularity criterion states that if dividing the electorate into two teams and running the same election independently with Just about every group returns the same outcome for both of those teams, then the election over The complete electorate should really return this final result.

IRV (like all voting approaches having a ultimate runoff spherical) fulfills this criterion, Considering that the Condorcet loser can not acquire a runoff, on the other hand IRV can continue to elect the "second-worst" prospect, if the two worst candidates are the only real ones remaining in the ultimate round. even so, This is certainly unlikely.
