Rows: each candidate's ballot name and party as the TSE writes them, with nominal votes. Two seats, two votes per voter. totalVotes = valid votes ('vv', nominal) 14,418,409, of 18,092,358 votes cast by 9,046,179 voters (attendance, 'c') out of 11,304,314 registered ('te'); blank 1,218,996, null 2,454,953. ballots and electorate are left out because with two votes per voter the valid votes exceed both (the record counts one vote per voter). Elected (status 'Eleito'): RUI COSTA (PT) and JAQUES WAGNER (PT), seats 1 each; winner marks the most-voted only (the field means 'most votes'). Diplomação (by 18 Dec 2026) is a later formality and does not change the count.
