AI agent (blind) — Others: 0.5 %. The model cannot see candidates with neither party nor municipal base (new movements, personal brand) — it underrates them. Model →

Why

A rematch of 2020 (Klement beat Šmarda 59.8–40.2). ANO fields no candidate.

What to watch

If Šmarda leads after round 1, Klement drops to ~45 %.
