Morena maintains the strongest position in trader assessments for the Sinaloa Congress election outcome, reflecting its dominant share of party affiliations—over 343,000 members compared to far smaller bases for rivals like the Partido Sinaloense and PRI—along with control of the current 65th Legislature. Recent sessions saw Morena-aligned groups secure the Mesa Directiva by consensus and approve an interim governor with a 31-vote majority, underscoring legislative influence ahead of the 2027 contest. Opposition parties including PAN, PRI, and MC have criticized power concentration and explored alliances, while external calls for unity against Morena highlight competitive pressures. National coalition trends with PT and PVEM allies further bolster Morena's implied probability, though security challenges and upcoming candidate selection processes introduce variables that could affect final seat distribution.
