A voting system used in single-member district systems and single-office elections in which voters can vote for, or approve of, as many candidates as they wish. Each candidate approved of receives one vote and the candidate with the most votes wins. The winner need not garner a majority of the votes.
Approval voting is a voting system used for elections, in which each voter can vote for as many or as few candidates as the voter chooses. It is typically used for single-winner elections, but can be extended to multiple winners. (However, multi-winner Approval voting does not return proportional results.)
