APA uses the Ware System for its presidential elections--a system that allows voters to rank their choices for the office rather than voting for just one candidate.

Under the system, voters rank the candidates in order of preference. If no candidate has a majority of the votes cast after the first count, ballots are then counted several times: On each count, the candidate with the lowest number of votes is eliminated from consideration, and the votes for that candidate are transferred to the voters' next choice. Ballots that indicate no additional choice are considered "exhausted."
