Interest in voting systems and voting system reform is growing in the United States. Voting systems—the procedures by which we cast votes and elect our public officials—are a crucial part of the democratic election process. The decision to use one kind of voting system rather than another has far-reaching political consequences. Among other things, voting systems help to determine which officials are elected to run our governments, the variety of parties that voters have to choose from at the polls, whether political minorities can win any representation, and whether the majority will rule.
