TSE EA20 result file, round 1, generated 21 Oct 2026 17:40:52 Brasília time: final totalisation ('tf': 's', 'and': 'f'), 7,106 of 7,106 polling sections totalised on 4 Oct 2026 at 20:05:51 (Brasília time, UTC-3). 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) 2,608,059, of 3,078,018 votes cast by 1,539,009 voters (attendance, 'c') out of 2,021,869 registered ('te'); blank 225,530, null 244,429. 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'): REINALDO AZAMBUJA (PL) and CAPITÃO CONTAR (PL), 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. Observed: the TSE result file for MS (senator, cargo 5, election 6259) shows the final totalisation ('tf': 's', 'and': 'f', all 7,106 polling sections) on 4 Oct 2026 at 20:05:51 Brasília time, recorded as 2026-10-04T23:05:51Z.
