Ulises Mejía Haro leads trader pricing at 47.5% for the June 2027 Zacatecas gubernatorial election, ahead of Verónica Díaz Robles at 28.5% and Alfonso Ramírez Cuéllar at 10.5%, as Morena maintains a substantial statewide preference edge. Recent GobernArte surveys show Mejía Haro consolidating his position in Morena's internal selection process with roughly 38-42% support among party voters, widening his advantage over other aspirants. The broad field of listed contenders and modest spreads reflect the early timeline, ongoing candidate vetting within parties, and limited general-election polling. Final nominee choices, opposition coalition dynamics, and any shifts in Morena's organizational strength ahead of the June 6 vote could widen or narrow gaps in implied probabilities.
