Mexican politics is full of paradoxes. Morena dominates the country politically, but that strength needs to be confronted by the opposition if democracy is to deliver its best results. A party as dominant as Morena can eliminate the alternatives that are essential to political competition. During the era of the all powerful PRI, political thinkers of the time sought to promote opposition forces to prevent the system from being seen as a perfect dictatorship, as Mario Vargas Llosa described it. That led to political reform and eventually to the alternation of power. Mexico began its transition toward democracy.
Today, Morena enjoys an advantage that for decades seemed reserved for the PRI: a nationwide political structure, an enormous territorial presence, and a narrative that has succeeded in identifying the party with the transformation of the country. For that reason, it is vital that its adversaries develop attractive political proposals for a society that has chosen democracy.
The opposition will have a major opportunity in the 2027 midterm elections to present its political platform to voters. 2027 will be a crucial year for Mexican politics. The offices at stake will shape the immediate future of national politics. They include 500 federal deputy seats; 17 governorships; 1,098 state legislative seats; 18,507 municipal positions; and 437 municipal boards, trusteeships, and council seats, for a total of 19,609 positions to be contested.
The opposition parties represent such a diverse political spectrum that they are clearly distinct from one another. In this sense, Morena, the dominant party, is a left-wing, national-popular party. The Institutional Revolutionary Party (PRI), which held power for 71 consecutive years and then returned for another six under Enrique Peña Nieto, is a center and center-right party. The National Action Party (PAN) is a right-wing, center-right party that governed for two six-year terms. Movimiento Ciudadano (MC) is a center and center-left party. The Labor Party is a left-wing party closely aligned with Morena.
Other parties include the Mexican Ecologist Green Party (PVEM), an environmentalist and pragmatic party; PAZ, a right-wing, socially conservative party; and Somos México, a center-left, social democratic party. The latter two obtained their registration in July 2026 and will participate in next year’s elections.
Morena faces a paradox of its own: concentrating so much power can be a source of strength, but it can also become a risk. When a political force controls the executive branch, Congress, the judiciary, and most state and local governments, checks and balances cease to be a democratic formality and become a necessity.
For that reason, the future of Mexican politics depends not only on how much the opposition can grow at the polls. It depends on whether it can recover a simple but fundamental idea: opposing does not mean saying no to everything; it means offering a different way of governing; it means creating credible alternatives. Morena, for its part, will have to demonstrate that it can exercise a majority while accepting political criticism made in good faith and with a constructive spirit.
