TSE EA20 result file, round 1, generated 10 Oct 2026 15:09:50 Brasília time: final totalisation ('tf': 's', 'and': 'f'), 37,675 of 37,675 polling sections totalised on 10 Oct 2026 at 15:07:39 (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. totalVotes = valid votes ('vv', nominal only: no party-label votes for this office) 8,394,627; ballots = attendance ('c') 9,845,867; electorate ('te') 12,842,517; blank 501,537, null 949,703. Elected in round 1 (absolute majority of valid votes, Constitution art. 28 with art. 77): DOUGLAS RUAS (PL), status 'Eleito'. Diplomação (by 18 Dec 2026) is a later formality and does not change the count. Observed: the TSE result file for RJ (governor, cargo 3, election 6259) shows the final totalisation ('tf': 's', 'and': 'f', all 37,675 polling sections) on 10 Oct 2026 at 15:07:39 Brasília time, recorded as 2026-10-10T18:07:39Z. That is a re-totalisation after polling day; the file does not show the time of the first one.
