Read the complete original research briefing

One previous institutional election, 17 August 2025. CNE proclaimed the mayor and five principal/five substitute councillors on 5 September 2025. The complete named roster is retained; final votes and party allocation remain unavailable. There are no two older elections of these new offices. 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 first-election statistical return and elected roster are imported. Its ballot-total and dataset-code notes remain visible. Later replacements and current control still require dated verification.

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 local poll supplied.

7. Unresolved issues and sources

One previous institutional election, 17 August 2025. CNE proclaimed the mayor and five principal/five substitute councillors on 5 September 2025. The complete named roster is retained; final votes and party allocation remain unavailable. There are no two older elections of these new offices. 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 first-election statistical return and elected roster are imported. Its ballot-total and dataset-code notes remain visible. Later replacements and current control still require dated verification. 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.

  • structural exception · open

    New-unit structural history exception: Only one earlier election exists for this new office. Its official party-vote vector and elected-candidate statistics are imported. Two older cycles are structurally inapplicable. Source ballot-total discrepancies and dataset-specific code joins remain documented. Predecessor votes are not assigned to this office.

  • other · open

    Official statistical ballot-total discrepancy: Published suffragants 8,130 exceed party votes + blank + null (8,129) by 1. Source values are retained; no missing vote is allocated.
