Preface
Economist Oskar Morgenstern, one of the founders of the theory of games, once wrote, "An experience of human development, it that where where mathematics has entered in a truly significant way, it has never been driven out again."

Voting methods lie at the intersection of political science, economics, and mathematics. Whether a group is electing a leader or choosing a course of action, their decision may depend on the voting method used as well as on the issues and the preferences of the voters.
