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.

Majority race: whoever gets the most votes wins, with no party quotient. The Senate renews two thirds and one third of its seats in alternating elections: that is why the number of seats changes from one election to the next.

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