Read the complete original research briefing

Council and parish votes before 2023 are candidate marks; 2023 is a closed-list ballot. Do not compare these vote shares as a continuous series. The 29 November 2026 ordinary cohort is reconciled to the CNE register. August precinct-distribution electors are a dated administrative count, not historical turnout or votes. Territorial boundary comparability, intervening outcomes and current control remain separate checks.

Source-reported control: Unverified. Current tenure requires separate dated evidence.

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.

Electoral register observations

Dated elector counts stay distinct from turnout and are not summed across overlapping contests.

6. Polling context

No local poll supplied.

7. Unresolved issues and sources

Council and parish votes before 2023 are candidate marks; 2023 is a closed-list ballot. Do not compare these vote shares as a continuous series. The 29 November 2026 ordinary cohort is reconciled to the CNE register. August precinct-distribution electors are a dated administrative count, not historical turnout or votes. Territorial boundary comparability, intervening outcomes and current control remain separate checks. The ordinary register is reconciled: 23 prefectures, 222 mayoralties, 222 municipal councils and 825 parish boards match the signed July 2026 call/list and August CNE codes. Borbón’s mayor/council and Miss Ecuador’s parish board are separate March 2027 first contests. Historical boundary comparability and some new-parish final returns remain open. Calacalí has final completion evidence but only preliminary rounded shares and secondary seat affiliations. Six first-election party vectors and elected rosters are recovered for the four 2024 parishes and Sevilla Don Bosco in 2025. Four small ballot-total discrepancies remain explicit. Shuar Pastaza remains preliminary. Fifteen July/August parish electorate differences are retained as dated observations.
