The term "hare system" refers to a voting system that is used to elect multiple candidates. It is named after the mathematician Thomas Hare who first proposed the idea in the mid-19th century. There are several synonyms for the term, including the Single Transferable Vote (STV), the Proportional Representation with the Single Transferable Vote (PR-STV), and the Preferential Voting System. All of these terms refer to a voting system that allows voters to rank their candidates in order of preference rather than simply selecting one candidate. The Hare system and its synonyms are often used in elections where multiple candidates are vying for a limited number of positions.
