Recent fractures in Colima's party alliances, including PVEM senator Virgilio Mendoza's October 9 resignation from state leadership and call for an opposition front with PAN, PRI, and MC, have fragmented the field ahead of the June 2027 legislative elections. Morena's designation of Rosa María Bayardo as state coordinator and receipt of the largest share of public campaign financing reinforce its position, yet polls show party preferences clustered between Morena (around 35%), PAN, PRI, and smaller shares for MC, PVEM, and PT. These developments sustain tight implied probabilities across multiple contenders for the congress majority, as potential coalitions, candidate registrations starting in December, and local factors such as municipal performance could shift seat outcomes before the April campaign period.
