TSE EA20 result file, round 1, generated 22 Oct 2026 15:05:52 Brasília time: final totalisation ('tf': 's', 'and': 'f'), 10,225 of 10,225 polling sections totalised on 22 Oct 2026 at 15:04:50 (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) 2,021,200; ballots = attendance ('c') 2,239,386; electorate ('te') 2,703,064; blank 76,589, null 136,522. Not in the rows, as the TSE does not count them as valid: votes for GERALDO CARVALHO (PSTU, 1,858, 'Anulado sub judice'); LOURDES MELO (PCO, 1,296, 'Anulado'); PROFESSOR JURITY (DC, 1,102, 'Anulado'); RAVENNA DA INCLUSÃO (DEMOCRATA, 819, 'Anulado'). Elected in round 1 (absolute majority of valid votes, Constitution art. 28 with art. 77): RAFAEL FONTELES (PT), status 'Eleito'. Diplomação (by 18 Dec 2026) is a later formality and does not change the count. Observed: the TSE result file for PI (governor, cargo 3, election 6259) shows the final totalisation ('tf': 's', 'and': 'f', all 10,225 polling sections) on 22 Oct 2026 at 15:04:50 Brasília time, recorded as 2026-10-22T18:04:50Z. That is a re-totalisation after polling day; the file does not show the time of the first one.
