TSE EA20 result file, round 1, generated 16 Oct 2026 11:46:19 Brasília time: final totalisation ('tf': 's', 'and': 'f'), 27,547 of 27,547 polling sections totalised on 4 Oct 2026 at 21:11:34 (Brasília time, UTC-3). 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) 11,465,782, of 13,394,848 votes cast by 6,697,424 voters (attendance, 'c') out of 8,516,465 registered ('te'); blank 1,089,553, null 837,203. ballots and electorate are left out because with two votes per voter the valid votes exceed both (the record counts one vote per voter). Not in the rows, as the TSE does not count them as valid: votes for RIC JONES (PCO, 2,310, 'Anulado sub judice'). Elected (status 'Eleito'): SANDERSON (PL) and MARCEL VAN HATTEM (NOVO), 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 RS (senator, cargo 5, election 6259) shows the final totalisation ('tf': 's', 'and': 'f', all 27,547 polling sections) on 4 Oct 2026 at 21:11:34 Brasília time, recorded as 2026-10-05T00:11:34Z.
