AI agent (blind) — Others: 2 %. The model cannot see candidates with neither party nor municipal base (new movements, personal brand) — it underrates them. Model →

Why

ANO's Ostrava runoff record is better than nationally but weak in governing years. Baránková's base is Poruba.

What to watch

Baránková leads by 5+ pp → ~62–35; Šimetka leads by 5+ → 85–88 %.
