AI agent (blind) — Others: 1 %. The model cannot see candidates with neither party nor municipal base (new movements, personal brand) — it underrates them. Model →

Why

Láska has a personal brand, but the parties that backed him in 2020 now back his rivals. Split centre-right field.

What to watch

Láska first → ~65–70 %; Láska third → out. Endorsements between rounds.
