Elected seats, from the TSE results. This is the composition that came out of the ballot boxes, not the one the chamber had over the legislative term: anyone who switched parties after the election does not change this number. The count adds up those elected, without recalculating the quotient, so it matches the legal size of the chamber. A single party has an absolute majority.

Votes by party (all, including those that elected no one)

Each party by its total votes (candidate votes + party-list votes), including those that won no seat.

Each senator is elected in their own state. This list brings together those elected in all states only to make it easier to look them up. Since states differ in size, the votes cannot be compared directly.

Choose a state above to see all candidates. Senator is elected by state: each state has its own race, and the national result is their sum.

Only two parties ran in these elections: ARENA and MDB. The previous party system was abolished by Institutional Act No. 2 of 1965, and Complementary Act No. 4 established that only two organizations could register candidates. The multiparty system was restored by the 1979 reform, and this database records 5 parties in 1982 and 29 in 1986.
