Mexico's ruling Morena party is on the verge of securing a two-thirds supermajority in the Senate following the defection of two opposition senators from the Democratic Revolution Party (PRD). The new members, Araceli Saucedo and José Sabino Herrera, joined Morena, which will allow the party to push through controversial constitutional reforms, including a judicial reform proposal to elect judges. This shift comes after the PRD lost its national party registration due to failing to secure 3% of the vote in recent elections. President-elect Claudia Sheinbaum welcomed the senators, describing their move as historic, while critics labeled them as 'traitors' to democracy. The proposed reforms have raised concerns among investors and prompted reactions from the U.S. and Canada due to fears of executive overreach and judicial independence undermined by electoral pressures. Congress is set to convene soon to debate these significant reforms.
