TSE EA20 result file, round 1, generated 24 Oct 2026 12:42:07 Brasília time: final totalisation ('tf': 's', 'and': 'f'), 21,418 of 21,418 polling sections totalised on 24 Oct 2026 at 12:41:15 (Brasília time, UTC-3). The file shows only its latest totalisation: this race was re-totalised after polling day, and the time of the first totalisation is not in the file. 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) 9,292,778, of 11,810,472 votes cast by 5,905,236 voters (attendance, 'c') out of 7,216,989 registered ('te'); blank 1,124,608, null 1,393,086. 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'): HUMBERTO COSTA (PT) and MARÍLIA ARRAES (PDT), 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 PE (senator, cargo 5, election 6259) shows the final totalisation ('tf': 's', 'and': 'f', all 21,418 polling sections) on 24 Oct 2026 at 12:41:15 Brasília time, recorded as 2026-10-24T15:41:15Z. That is a re-totalisation after polling day; the file does not show the time of the first one.
