Political parties in Brazil play a crucial role in the country's democratic system. The Brazilian political landscape is characterized by a multi-party system, with numerous parties representing a wide range of ideologies and interests. Major parties include the Workers' Party (PT), Brazilian Democratic Movement (MDB), and Social Liberal Party (PSL), among others. These parties participate in elections at various levels, influencing legislation and governance. Elections in Brazil are held every four years, with voters selecting representatives for the National Congress, state assemblies, and local governments. Political parties are essential for organizing electoral campaigns and mobilizing support. They also contribute to the formation of coalitions, which are often necessary to achieve a majority in the Chamber of Deputies and the Senate.
