2018 marks a turning point in Mexican politics as MORENA rose to become a major political force and shifted the party system. MORENA, a left-leaning party founded by Andrés Manuel López Obrador and allies, capitalized on public frustration with corruption and governance. In that year’s elections, AMLO won the presidency with a large mandate, and Morena gained substantial representation in the legislature and in state governments, signaling a realignment away from the long-dominant PRI and the traditional PAN. This change reshaped who could win national power, influenced policy agendas, and altered coalition dynamics for years to come. The other options don’t fit the historical record for 2018: there wasn’t a new constitution adopted, Mexico’s fundamental charter remains the 1917 constitution with later amendments; there wasn’t a complete halt to electoral reforms; and Mexico did not join a new regional trade bloc in that year.
