**Verónica Díaz Robles leads the Zacatecas gubernatorial market at 80.5% implied probability ahead of the June 2027 election, with Ulises Mejía Haro at 8.5% and all other listed candidates at 0.4% or lower.** Her positioning stems from Morena’s national leadership designating her in mid-September 2026 as state coordinator for the defense of the transformation, following internal surveys that placed her first. This role effectively designates her as the party’s presumptive nominee in a state where Morena and its allies hold the governorship under David Monreal and command the strongest partisan preference. Earlier 2026 polling had shown Mejía Haro ahead in raw preferences among Morena identifiers, but the leadership decision resolved the contest in Díaz’s favor despite reported internal pushback from other aspirants. With the formal nomination process still ahead and the general election more than eight months away, traders treat the recent party consolidation around Díaz as the dominant signal for her eventual victory.
