TSE EA20 result file, round 1, generated 4 Oct 2026 21:18:59 Brasília time: final totalisation ('tf': 's', 'and': 'f'), 4,384 of 4,384 polling sections totalised on 4 Oct 2026 at 20:59:57 (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) 1,650,411, of 1,927,620 votes cast by 963,810 voters (attendance, 'c') out of 1,180,433 registered ('te'); blank 93,579, null 180,376. ballots and electorate are left out because with two votes per voter the valid votes exceed both (the record counts one vote per voter). Not in the rows, as the TSE does not count them as valid: votes for HELIO RODRIGUES BOLSONARO (DEMOCRATA, 3,254, 'Anulado sub judice'). Elected (status 'Eleito'): EDUARDO GOMES (PL) and ALEXANDRE GUIMARÃES (MDB), 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 TO (senator, cargo 5, election 6259) shows the final totalisation ('tf': 's', 'and': 'f', all 4,384 polling sections) on 4 Oct 2026 at 20:59:57 Brasília time, recorded as 2026-10-04T23:59:57Z.
