TSE EA20 result file, round 1, generated 4 Oct 2026 21:08:18 Brasília time: final totalisation ('tf': 's', 'and': 'f'), 2,270 of 2,270 polling sections totalised on 4 Oct 2026 at 19:07:20 (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) 439,647; ballots = attendance ('c') 487,971; electorate ('te') 613,316; blank 8,926, null 39,398. No candidate won an absolute majority of valid votes: MAILZA ASSIS (PP) and ALAN RICK (REPUBLICANOS) 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 AC (governor, cargo 3, election 6259) shows the final totalisation ('tf': 's', 'and': 'f', all 2,270 polling sections) on 4 Oct 2026 at 19:07:20 Brasília time, recorded as 2026-10-04T22:07:20Z.
