TSE EA20 result file, round 1, generated 15 Oct 2026 09:08:09 Brasília time: final totalisation ('tf': 's', 'and': 'f'), 6,969 of 6,969 polling sections totalised on 4 Oct 2026 at 20:22:29 (Brasília time, UTC-3). 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) 1,651,394; ballots = attendance ('c') 1,817,921; electorate ('te') 2,243,988; blank 74,774, null 89,910. Not in the rows, as the TSE does not count them as valid: votes for RICO PINHEIRO (PRTB, 671, 'Anulado sub judice'); ELISSON (AGIR, 1,172, 'Anulado sub judice'). No candidate won an absolute majority of valid votes: CELINA LEÃO (PP) and LEANDRO GRASS (PT) go to the runoff of 25 Oct 2026 (status '2º turno'), so no winner is marked. Diplomação (by 18 Dec 2026) is a later formality and does not change the count. Observed: the TSE result file for DF (governor, cargo 3, election 6259) shows the final totalisation ('tf': 's', 'and': 'f', all 6,969 polling sections) on 4 Oct 2026 at 20:22:29 Brasília time, recorded as 2026-10-04T23:22:29Z.
