Who really allies with MORENA? The voting record tells a different story

The accusation that Movimiento Ciudadano (MC) secretly allies with MORENA inverts the empirical reality of Mexican legislative politics. Analysis of congressional voting records from 2018-2026 reveals that MC has been the most consistent opposition party, while PRI provided the critical votes enabling MORENA's most controversial constitutional reforms—and a PAN senator delivered the decisive vote for the 2024 judicial reform that opponents called Mexico's greatest democratic setback.

The "MC-MORENA ally" narrative originates almost exclusively from the Va por México coalition (PRI-PAN-PRD) and appears designed to pressure MC into electoral alliances and deflect attention from documented instances of PRI and PAN providing crucial votes to MORENA. Meanwhile, 92% of MORENA's gubernatorial candidates came from PRI or PRD backgrounds, and at least 14 ex-PRI members now hold high positions in the MORENA-aligned government—equaling the entire PRI Senate caucus.

The 2022 Guardia Nacional vote proved PRI was MORENA's essential partner

The September 2022 extension of Armed Forces participation in public security represents the clearest evidence of a PRI-MORENA legislative alliance. MORENA lacked the two-thirds supermajority for this constitutional reform—until PRI broke from the Va por México coalition to provide 64 crucial deputy votes and at least 9 senator votes.

The Chamber of Deputies approved the reform 335-152 on September 14, 2022. PRI Deputy Yolanda de la Torre formally presented the initiative, and PRI senators including Sylvana Beltrones, Eruviel Ávila, and Manuel Añorve voted with MORENA. Only three PRI senators—Miguel Ángel Osorio Chong, Claudia Ruiz Massieu, and Beatriz Paredes—broke party ranks to vote with the opposition.

On this vote, MC voted entirely against, with coordinator Clemente Castañeda declaring: "Don't count on us for this atrocity." The pattern established in 2022 fundamentally contradicts the narrative that MC enables MORENA: when constitutional reforms required opposition support, PRI delivered while MC refused.

The 2024 judicial reform proves who actually defected

The September 2024 judicial reform—establishing popular election of judges—required exactly 86 Senate votes. The oficialista coalition held 85 after two PRD senators defected to MORENA before the session. The 86th vote came from PAN Senator Miguel Ángel Yunes Márquez, who staged a dramatic return to the chamber after requesting sick leave, delivered a speech declaring "I am neither a coward nor a traitor," and voted with MORENA.

The PAN immediately expelled Yunes and his father from the party. Yunes formally joined MORENA in February 2025.

How did each party actually vote on this reform?

MC voted unanimously against the judicial reform in both chambers and subsequently filed constitutional action 167/2024 challenging it. The controversial absence of MC Senator Daniel Barreda—who claimed he was "detained" in Campeche to prevent his vote—meant one fewer opposition vote, but Barreda had publicly committed to vote against and did not vote for the reform. The actual defector was a PAN senator.

Tracking the comprehensive voting pattern across major reforms

Analysis across twelve major controversial reforms from 2018-2025 reveals a consistent pattern where MC opposes MORENA while PRI and PAN show selective collaboration:

Reforms where ALL opposition parties voted against MORENA:

• Constitutional Electricity Reform (April 2022) – defeated
• Constitutional Electoral Reform (December 2022) – defeated
• Plan B Electoral Reform (February 2023)
• Judicial Reform (September 2024)
• Supremacía Constitucional (October 2024)

Reforms where PRI voted WITH MORENA while MC opposed:

• Guardia Nacional Extension (September 2022) – PRI provided supermajority
• Revocación de Mandato (2019) – PRI and PRD supported

The TEPJF reform of March 2023 shows the starkest contrast: MORENA, PRI, PAN, and PRD voted together to limit the Electoral Tribunal's powers. MC was the only party to vote against, releasing a statement: "PRI, PAN, and PRD join MORENA to weaken the Electoral Tribunal; Movimiento Ciudadano defends democracy."

The quantitative picture is striking. Despite holding only 67% of Senate seats, MORENA reforms obtained 80% average support during the first year of the current legislature, according to analysis by Mexicanos Contra la Corrupción y la Impunidad. This gap indicates opposition fragmentation—but the fragmentation comes primarily from individual defectors (Yunes, López Castro) and PRI's strategic collaboration, not from MC voting with the government.

MORENA's composition reveals the real PRI connection

The accusation that MC is MORENA's hidden partner ignores the documented reality that MORENA is substantially composed of former PRI members. According to 2021 analysis, 92% of MORENA's gubernatorial candidates had backgrounds in PRI, PRD, or both—only one candidate (Marina del Pilar Ávila) originated within MORENA itself.

Prominent PRI politicians who switched to MORENA include:

• Julio Menchaca (Governor of Hidalgo): 35 years in PRI before switching in 2017
• Américo Villarreal (Governor of Tamaulipas): 34 years in PRI before switching in 2017
• Cynthia López Castro: Won Senate seat for PRI in 2024, switched to MORENA within two months
• Alejandro Murat: Former PRI Governor of Oaxaca, now chairs Senate Foreign Relations Committee for MORENA

At least six former PRI governors received diplomatic posts from AMLO and Sheinbaum after their states fell to MORENA: Claudia Pavlovich (Sonora) became consul in Barcelona, Quirino Ordaz (Sinaloa) became ambassador to Spain, and Omar Fayad (40 years in PRI) became ambassador to Norway. PRI leadership accused these governors of "delivering their states in exchange for impunity."

The July 2025 count showed 14 ex-PRI members holding high positions aligned with MORENA—equaling the entire PRI Senate caucus.

Where the MC accusation originates and what evidence exists

The "MC is MORENA's ally" narrative comes primarily from three sources: PRI President Alejandro "Alito" Moreno, PAN President Marko Cortés, and PRD leadership. Their specific accusations:

• Moreno has called MC "esquiroles" (scabs), "employees of MORENA," and Dante Delgado "the biggest traitor of this country"
• Cortés labeled MC "the Judas of the opposition" in June 2022
• Va por México collectively accused MC of running a "servile campaign" to divide the opposition (May 2023)

The evidence accusers cite consists mainly of: MC's refusal to join the Va por México coalition since 2020; MC's historical alliance with AMLO from 2006-2012; a June 2021 Proceso investigation alleging a secret December 2020 pact; and MC's independent 2024 presidential candidacy (Jorge Álvarez Máynez, 10.32% of vote), which split opposition votes.

MC's response has been consistent: Dante Delgado published an open letter to AMLO in February 2021 calling his presidency "authoritarian" and declaring "we are not accomplices"; MC argues that being attacked by both MORENA and Va por México proves their independence; and they point to their voting record opposing MORENA's major reforms.

The critical weakness in the accusation is the voting evidence. On every major controversial constitutional reform—judicial reform, Guardia Nacional militarization, supremacía constitucional—MC voted against MORENA while it was PRI that provided enabling votes in 2022 and a PAN senator who provided the decisive vote in 2024.

Two exceptions reveal MC's pragmatic rather than submissive approach

MC has voted with MORENA on two notable occasions, which accusers cite as evidence. First, the April 2022 lithium nationalization reform: MC voted in favor while PRI and PAN walked out in protest. Second, the September 2025 Guardia Nacional ratification reform: MC voted in favor while PAN and PRI opposed.

On lithium, MC's position aligned with resource nationalism that enjoys broad public support. On the 2025 ratification reform, MC justified their vote by arguing the reform "corrects the omission" of parliamentary control over military appointments and strengthens Congress as a "democratic counterweight."

These exceptions reveal a pragmatic party willing to support specific measures on their merits rather than automatic opposition. Crucially, both votes occurred on reforms that did not require supermajorities—meaning MC's votes were not decisive for passage. This contrasts sharply with PRI providing the essential supermajority votes for the 2022 militarization reform and Yunes providing the essential 86th vote for judicial reform.

Conclusion

The empirical record contradicts the accusation that Movimiento Ciudadano is MORENA's hidden ally. On every major controversial constitutional reform from 2018-2026, MC voted with the opposition bloc. The parties that actually provided crucial votes enabling MORENA's most contentious reforms were PRI in 2022 (Guardia Nacional extension) and PAN in 2024 (judicial reform via Yunes defection). Meanwhile, MORENA's composition—92% ex-PRI/PRD gubernatorial candidates, 14 ex-priístas in high positions, six former PRI governors receiving diplomatic posts—demonstrates the institutional convergence that the "MC ally" narrative obscures.

The accusation appears designed to pressure MC into joining Va por México and to deflect from the documented voting record showing PRI-MORENA cooperation on security militarization. MC maintains strategic independence that serves its institutional interests—refusing coalitions, occasionally voting pragmatically—but their consistent opposition to MORENA's signature constitutional reforms means calling them "MORENA's ally" requires ignoring the actual evidence of who voted how, when it mattered most.
