Morena Secures House Supermajority, Falls Short in Senate as Mexico Braces for Historic Changes

Mexico's electoral body has confirmed ruling party Morena and its allies will hold a supermajority in the lower house, but fall short of the same in the Senate. The confirmation marks a significant political shift as the country prepares for constitutional reforms and its first female president, Claudia Sheinbaum.

Mexico's electoral authority confirmed on Friday that ruling party Morena and its allies achieved a two-thirds supermajority in the lower house. This guarantees 364 seats, enabling constitutional amendments without opposition consensus.

However, in the Senate, Morena will control 83 of 128 seats, falling just short of an 85-seat supermajority. The opposition had argued that the ruling coalition deserved fewer seats, but the electoral body ruled otherwise.

INE's presiding counselor Guadalupe Taddei emphasized that electoral results are determined by citizens' votes. The upcoming legislative session will see attempts to pass various constitutional reforms, including controversial judicial and electoral changes, ahead of Claudia Sheinbaum's historic presidency starting in September.
