Proportional systems are used for many elections in the United States. Two cities use choice voting. More than 60 localities use cumulative voting, and more than 100 localities use limited voting. Until 1980, Illinois used cumulative voting to elect state representatives, and the Chicago Tribune and many other state leaders support its return. Proportional systems are used to elect most delegates to the Democratic national convention and many delegates to the Republican national convention.
Several states require corporations to elect their boards with cumulative voting.
Nearly every well-established democracy in the world uses a proportional system without the problems with coalitions experienced in Italy and Israel. Representation thresholds as low as four percent still promote two major parties. The Voters' Choice Act simply allows states to explore other options. Such exploration certainly is warranted. Our voter turnout is among the world's lowest.
