**Morena holds a leading position in the Sinaloa state congress race at 64% implied probability, ahead of PRI at 26% and smaller shares for PVEM, PT, PAN, and MC.** The June 6, 2027, concurrent election will renew the full local legislature alongside the governorship and other posts. Morena benefits from its established territorial structure, recent internal selection of Imelda Castro as state coordinator, and ongoing candidate registration for federal and local positions. Scandals tied to former governor Rubén Rocha Moya and U.S. accusations have created headwinds and prompted interim leadership changes, yet party preference polls continue to place Morena ahead of a fragmented opposition. Potential PRI-PAN or broader alliances could narrow gaps in specific districts, while high undecided rates in recent surveys leave room for shifts before formal campaigning intensifies. Trader consensus reflects Morena’s current organizational edge in a state it has controlled since 2021.
