Sheinbaum’s Electoral Reform: A Power Play Within Mexico’s Ruling Alliance

Mexican President Claudia Sheinbaum has proposed a constitutional electoral reform aimed at reshaping Mexico’s political landscape. While presented as a measure to reduce electoral fraud, cut costs, and strengthen financial oversight, the reform appears to be a strategic maneuver to consolidate power within her MORENA party and assess the loyalty of its allies, the Labor Party (PT) and the Green Party.

The Core of the Proposed Reform

The proposed reform centers on modifying proportional representation in Congress, often referred to as “plurinominales.” Sheinbaum seeks to require candidates for these proportional representation seats to secure votes directly from citizens, rather than relying on party lists. This change would impact the number of seats allocated through proportional representation in the Chamber of Deputies, maintaining a total of 500 seats with 300 filled by majority vote and 200 through proportional representation [1]. The reform aims to regulate the apply of artificial intelligence in campaigns and restructure vote-counting procedures [1].

A Shifting Power Dynamic

The current governing coalition, known as “4T” (Fourth Transformation), is comprised of MORENA, the PT, and the Green Party. While MORENA initiated the reform, its success hinges on the support of these allied parties. Historically, the PT has aligned with leftist parties, while the Green Party has demonstrated a more pragmatic approach, aligning with various political forces over time. Both parties have benefited from proportional representation, gaining access to elected positions and public funding.

Sheinbaum’s proposal to reduce the number of plurinominal seats and tighten party financing threatens the PT and Green Party’s access to these benefits. This has led to resistance from both parties, as approving the reform could diminish their legislative weight and negotiating power.

Measuring Loyalty and Consolidating Control

Despite potentially lacking the necessary votes for approval, Sheinbaum moved forward with presenting the reform to Congress. This suggests the proposal’s primary objective may not be its passage, but rather to gauge the loyalty of her allies and expose potential betrayals. By forcing the PT and Green Party to take a stance, Sheinbaum aims to identify those willing to cooperate and those who might prioritize their own interests.

The reform presents a dilemma for the allied parties. Supporting the reform would consolidate MORENA’s leadership at their expense, while opposing it would position them as obstacles to Sheinbaum’s “transformation” agenda. The decision hinges on their perceived electoral strength, particularly at the local level.

Potential Outcomes and Implications

If Sheinbaum fails to secure the necessary votes, she risks losing some governorships but could strengthen MORENA’s position in the long run. A failed reform could as well jeopardize the “4T” coalition’s qualified majority in Congress, potentially hindering the passage of future legislation. However, Sheinbaum appears willing to accept this risk in order to initiate detaching the “4T” brand from the PT and Green Party, ultimately monopolizing it within MORENA.

The proposed reform could have implications for upcoming elections, potentially opening the door for alternative candidates from MORENA to challenge incumbents from the PT and Green Party in key regions. This could lead to a complete breakdown of the “4T” alliance and a fierce electoral battle in 2027.

Is This Reform Stillborn?

While some analysts view the electoral reform as unlikely to pass, understanding its underlying political motivations reveals a more complex picture. The reform’s true impact may not be on the electoral system itself, but on the dynamics within the ruling alliance. It is a strategic move to reshape the political landscape and consolidate MORENA’s power, even at the cost of fracturing its coalition.
