What is Elections in Brazil?

Brazil elects on the national level a head of state—the president—and a legislature. The president is elected to a four-year term by absolute majority vote through a two-round system. The National Congress has two chambers. The Chamber of Deputies has 513 members, elected to a four-year term by proportional representation. The Federal Senate has 81 members, elected to an eight-year term, with elections every four years for alternatively one-third and two-thirds of the seats. Brazil has a multi-party system, with such numerous parties that often no one party has a chance of gaining power alone, and so they must work with each other to form coalition governments.
