Morena holds a commanding position in trader sentiment for the Sinaloa state congress outcome due to its dominant party infrastructure, including over 343,000 registered affiliates compared to far smaller bases for rivals like PAS or PRI. Recent internal Morena surveys and independent polling ahead of the 2027 elections show the party and its allies (PT and PVEM) leading with around 43% preference, well ahead of PAN, PRI, and MC. The current Morena-led majority in the 65th Legislature continues to consolidate control, as evidenced by the September 2026 consensus election of the Mesa Directiva and the October 2026 interim gubernatorial appointment. Opposition parties face structural disadvantages from lower affiliation numbers and fragmented support, while ongoing security challenges in the state have not shifted the established party balance reflected in the latest measurements.
