Although there were fears of electoral fraud in Mexico's 2018 presidential elections, the results gave a mandate to AMLO. On 1 December 2018, Andrés Manuel López Obrador was sworn in as the new President of Mexico. After winning a landslide victory in the July 2018 presidential elections, he became the first leftwing president for decades. In June 2021 midterm elections, López Obrador's left-leaning Morena’s coalition lost seats in the lower house of Congress. However, his ruling coalition maintained a simple majority, but López Obrador failed to secure the two-thirds congressional supermajority. The main opposition was a coalition of Mexico’s three traditional parties: the center-right Revolutionary Institutional Party, right-wing National Action Party and leftist Party of the Democratic Revolution.
