Morena and Allies Secure Supermajority in Mexico's Lower House

Mexico's electoral authority confirmed that the ruling party Morena and its allies will hold a two-thirds supermajority in the lower house, following a debate over seat distribution. With 364 seats, Morena surpasses the 334-seat threshold needed for constitutional amendments without opposition consensus.

Mexico's electoral authority has confirmed that the ruling party Morena and its allies will hold a two-thirds supermajority in the lower house, effective from the upcoming session in September. This decision follows a lengthy debate over the seat distribution.

The electoral authority, INE, announced that Morena and its allies secured 364 seats in the lower house. This comfortably exceeds the two-thirds majority, or 334 votes, needed to amend the constitution without requiring consensus from the opposition parties.

The formal ratification of the June 2 election results came after objections from opposition parties, who argued that the ruling coalition should have fewer seats. They based their argument on an interpretation of the electoral system that prioritizes representation by individual parties rather than by coalitions.
