Piauí — Governor
54 state ballots plus eight specifically called municipal mayor/vice tickets. Municipal dates are 25 October or 6 December 2026. State and local actual-event sequences, annulments, source comparability and current control retain office-specific review gaps. Roraima 2010 is recovered from official section files; the June 2026 supplementary proclamation remains unresolved. Rio’s 2022 votes and seats are verified against the signed March 2026 recount, with 70 named elected deputies.

National polling context: National presidential poll; context for subnational races — Datafolha; fieldwork 2026-09-01 to 2026-09-02. Sample 2,002; reported margin of error ±2.00 percentage points.

National polling context: National presidential approval; context for subnational races — AtlasIntel / Bloomberg; fieldwork 2026-07-22 to 2026-07-27. Sample 5,021; reported margin of error ±1.00 percentage points. Earlier comparison wave; named officeholder and question wording retained. Poll report
National polling context: National presidential approval; context for subnational races — AtlasIntel / Bloomberg; fieldwork 2026-08-25 to 2026-08-30. Sample 5,014; reported margin of error ±1.00 percentage points. Rounded approval fell from 48% to 45%, and disapproval rose from 51% to 53%. This supplies a national headwind indicator for Lula-aligned candidates, but Brazilian state coalitions differ and individual state polling takes precedence. Overview values are rounded to whole percentage points. Poll report
First round 4 October 2026; governor runoff 25 October where required. TSE ordinary-election returns aggregated once from state files, excluding the duplicate national BR file. Party votes are not governing coalition control. Legislative votes include nominal plus valid list votes. Judicial retotalizations and changed party labels require review. The 2014 file uses legacy nominal/list fields; later files separately identify valid, converted and subjudice votes. This is an explicit definition-comparability limitation.
