Right now, there are two places in the US that use Approval Voting: Fargo, North Dakota, and St. Louis, Missouri. Both cities have seen extremely high satisfaction with Approval Voting with voters saying they enjoyed the process and that they would like to continue using it. Significantly, both cities have seen a large percentage of voters decide to approve of multiple candidates, meaning the added function of Approval Voting is being utilized to produce more representative elections.
