AMBATO / TUNGURAHUA — Mayor

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.

Historical competition

Competitiveness index for a verified actual-event sequence withheld. Actual-event and/or comparability review incomplete.

Provisional imported-series CI: 63.4/100. This uses the three displayed comparison cycles and retains the open event/boundary audit. It does not confirm the latest three actual completed elections.

Grouped party-share volatility: latest interval 29.8 points; earlier interval 58.9 points; two-interval mean 44.3 points.

Grouped Pedersen lower bound (percentage points). Six named standalone categories in CNE returns, including explicit short/expanded CREO, SUMA and Alianza PAIS labels. Mixed alliances, successor movements and other parties stay Other. This does not attribute Revolución Ciudadana votes to Alianza PAIS. Multi-mark and otherwise ineligible histories remain excluded. An interval is withheld if either election has no list mapped to an explicit named group. This is aggregate share change, not individual voter switching. Event review: Actual-event and/or comparability review incomplete

Current government and control: Unverified. Local government-risk forecast: unassessed.

Polling: no vetted current evidence included for this office.

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.
