Sistema eleitoral proporcional de lista aberta: críticas da ciência política ao sistema eleitoral do Brasil

The open-list proportional electoral system is used in democracies such as Brazil for the election of its legislative representatives. This system, however, has been subject to criticism in political science, both in Brazil and internationally, due to its effects on party structure, voter behavior, and the political process in general. This article examines the main theoretical criticisms of the open-list proportional system, discussing issues such as party fragmentation, campaign personalization, distortion of the popular will, intraparty competition, difficulty in electoral accountability, and the tendency toward personalist voting.
