Lorenia Valles Sampedro leads trader sentiment for the 2027 Sonora gubernatorial race after Morena designated her state coordinator in late September 2026 following an internal poll among six aspirants. This positions her as the party's presumptive nominee to succeed incumbent Alfonso Durazo in a state where Morena holds the governorship and benefits from national alignment. Recent polling shows her with roughly 40% support, well ahead of potential opponents including Antonio Astiazarán Gutiérrez and Luis Donaldo Colosio Riojas. PT and PVEM have signaled backing for her, while other Morena figures received local nominations to preserve unity. Pre-campaigns open in December 2026 ahead of the June 2027 vote, with opposition parties still finalizing candidates and possible alliances. These developments underpin the market's emphasis on Valles as the frontrunner while leaving room for shifts once formal nominations and campaigns begin.
