Read the complete original research briefing
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.

5. Officeholder evidence
Dated roster observations are not automatically current tenure. The source current-office flag means this office is tracked now, not that the last winner still holds it.
No officeholder observation supplied.
6. Polling context
No local poll supplied.
National context is listed on the polling page. It is not a local forecast.
7. Unresolved issues and sources
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. Roraima legal certification, Rio and other specific replacement/current-control cases remain open. Eight municipal replacement tickets are tracked; ordinary municipal renewals are outside the window. Public-vote baselines for Alagoas and Amazonas are supplied separately from their indirect selections. Roraima’s primary 2010 cycle is recovered; the June 2026 proclamation is still unresolved. Rio’s signed 2026 legislative retotalization verifies the imported 2022 votes and seats, with 70 named elected deputies added; later membership and governing-coalition control still need dated verification.
