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) 4,029,927, of 4,697,224 votes cast by 2,348,612 voters (attendance, 'c') out of 2,987,584 registered ('te'); blank 319,565, null 347,732. 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'): RENATO CASAGRANDE (PSB) and EVAIR DE MELO (REPUBLICANOS), 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.
