**The party also secured majorities in the state of Mexico and Baja California legislatures.**

On Monday, Mexico's Morena party won the legislative elections in three key states. The victories covered the state of Mexico, Baja California and Oaxaca. The results gave Morena control of all three state congresses.

In Oaxaca, Morena outpaced the Institutional Revolutionary Party, the Ecologist Green Party and the Labor Party to claim the Congress The party's slate secured a clear plurality of seats.

The State of Mexico election saw Morena defeat candidates from the Green Party, the Citizens' Movement and the National Action Party. Morena's candidates captured the majority of seats in the lower house. The win reinforced the party's dominance in the nation's most populous state.

Baja California's Congress also turned to Morena, with the party surpassing the National Action Party, the Green Party and the Citizens' Movement. Morena's vote share translated into a governing majority. The result extended the party's reach to the country's northwestern border.

## Analysis

Morena's sweep of three legislatures strengthens its position in the federal system. Controlling the congresses of the state of Mexico, Baja California and Oaxaca gives the party a broader platform to coordinate state policies with national priorities. The added seats may also affect the balance of power in the Chamber of Deputies if state legislators influence federal party lists. However, the expansion does not eliminate opposition representation entirely.

In Oaxaca, the shift from parties such as PRI, PVEM and PT to Morena could redirect state spending toward the president's agenda. The change may also reshape the political calculus for indigenous and rural constituencies that historically backed opposition groups. The durability of this realignment remains uncertain.

The victories come ahead of upcoming mid-term elections, raising questions about how the party will manage internal factions and voter expectations. Maintaining cohesion across disparate regions like the central state of Mexico, the northern Baja California and the southern Oaxaca will test party organization. Opposition parties may regroup to contest future contests, but their reduced presence in these legislatures limits immediate leverage. The longer-term impact will depend on how effectively Morena translates legislative control into policy outcomes.
