PVEM split could leave Mexico’s governing bloc short of Senate supermajority
Virgilio Mendoza Amezcua has resigned as head of the Green Party in Colima, and may also leave its Senate group.
The possible departure could weaken the governing alliance of Morena, the Green Party and the Labor Party in Mexico’s Senate.
Morena has 66 senators, while the Green Party could provide 12 votes after accounting for Mendoza’s possible exit and one senator who votes against the allies.
The Labor Party has six senators, giving the bloc a possible total of 84 votes.
That would leave it two votes short of the qualified majority needed to pass constitutional reforms.
Mendoza had been considered a possible candidate for Colima governor, but the Green Party confirmed its alliance with Morena and support for Morena’s candidate, Rosi Bayardo.
The sources do not say whether Mendoza will leave the Senate group or what will happen next.
Senator Virgilio Mendoza Amezcua’s resignation from the Green Party’s leadership in Colima and possible departure from its Senate bloc could leave Mexico’s governing coalition short of a supermajority.
The coalition could have 84 Senate votes, two short of the number needed for a qualified majority, according to El Financiero.
Morena has 66 senators, while its allies include 14 Green Party senators and six from the Labor Party.
The estimate falls to 12 Green Party votes because Luis Armando Melgar votes against the allies and Mendoza may leave the bloc.
Mendoza resigned after the Green Party confirmed its alliance with Morena and backed Rosi Bayardo for Colima governor.
