The electoral threshold, or election threshold, is the minimum share of all the votes cast that a candidate or political party requires to achieve before they become entitled to representation or additional seats in a legislature. This limit can operate in various ways, e.g. in party-list proportional representation systems where an electoral threshold requires that a party must receive a specified minimum percentage of votes, either nationally or in a particular electoral district, to obtain seats in the legislature. In Single transferable voting the election threshold is called the quota and it is possible to pass it by use of first choice votes alone or by a combination of first choice votes and votes transferred from other candidates based on lower preferences. In mixed-member-proportional (MMP) systems the election threshold determines which parties are eligible for top-up seats in the legislative body.
The Workers' Party is a centre-left to left-wing political party in Brazil that is currently the country's ruling party. Some scholars classify its ideology in the 21st century as social democracy, with the party shifting from a broadly socialist ideology in the 1990s. Founded in 1980, PT governed at the federal level in a coalition government with several other parties from 1 January 2003 to 31 August 2016. After the 2002 parliamentary election, PT became the largest party in the Chamber of Deputies and the largest in the Federal Senate for the first time. With the highest approval rating in the history of the country, President Luiz Inácio Lula da Silva is PT's most prominent member. Dilma Rousseff, also a member of PT, was elected twice but did not finish her second term due to her impeachment in 2016. The party came back to power with Lula's victory in the 2022 presidential election.
The Green Party is a political party in Brazil. It was constituted after the military dictatorship period and, like other green parties around the world, is committed to establishing a set of policies on ensuring social equity and sustainable development. One of the party's founding members was the journalist and former anti-dictatorship revolutionary Fernando Gabeira, Alfredo Sirkis and Carlos Minc. The founding of the Rio de Janeiro section of the Brazilian Green Party was led by a delegation from the southern Brazilian state of Santa Catarina, composed among others by Olga Maria Carvalho Luz, Luiz Henrique Gevaerd Odebrecht, Marcos Bayer, and Consuelo Luz Lins.
The National Congress of Brazil is the legislative body of Brazil's federal government. Unlike the state legislative assemblies and municipal chambers, the Congress is bicameral, composed of the Federal Senate and the Chamber of Deputies. The Congress meets annually in Brasília from 2 February to 22 December, with a mid-term break taking place between 17 July and 1 August.
The Liberal Party was a conservative political party of Brazil, it merged into the Party of the Republic in 2006. The Pentecostal Universal Church of the Kingdom of God heavily influenced the party after 1999. In the 2002 election, José Alencar of the PL was the running mate of Lula da Silva and became the vice president. At the legislative elections, 6 October 2002, the party won 26 out of 513 seats in the Chamber of Deputies and three out of 81 seats in the Senate of Brazil and supported Luiz Inácio Lula da Silva's government. Some of its members were investigated following corruption allegations and suspected involvement in the so-called "Mensalão scandal". The Universal Church has now partially left PL to create a new party named Brazilian Republican Party (PRB) in 2005.
Progressistas is a centre-right to right-wing political party in Brazil. Founded in 1995 as the Brazilian Progressive Party, it emerged from parties that were successors to ARENA, the ruling party of the Brazilian military dictatorship. A pragmatist party, it supported the governments of presidents Fernando Henrique Cardoso, Luiz Inácio Lula da Silva, Dilma Rousseff, Michel Temer and Jair Bolsonaro. Largely it was the party of the politics of Paulo Maluf, a former governor and mayor of São Paulo. Of all political parties, in corruption investigation Operation Car Wash, the Progressistas had the most convictions.
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.

As no presidential candidate received more than 50% in the first round of voting, a second round was held on 31 October to choose a successor to Luiz Inácio Lula da Silva of the Workers' Party (PT), who was constitutionally ineligible to run for a third term as he has already served two terms after winning the elections in 2002 and being re-elected in 2006.
