Recent polling in Sinaloa shows Morena holding a narrow edge in party preference at around 29%, closely trailed by PAN at 28% and PRI at 22%, reflecting a competitive landscape for state congress seats in the 2027 elections. Ongoing talks of opposition coalitions between PAN and PRI, potentially including other parties, could consolidate support and narrow Morena's advantage if formalized. Security challenges tied to organized crime and recent political transitions, including the interim governorship, heighten voter focus on stability. These elements sustain tight implied probabilities across leading parties, with trader consensus sensitive to alliance developments and local turnout patterns.
