The Reshaping of Mexico’s Political Elite in the 21st Century
The architecture of Mexico’s political system has undergone a tectonic transformation that can’t simply be understood as a change of party labels in power, but rather as a process of institutional and human transvasement from the historic Institutional Revolutionary Party (PRI) toward the National Regeneration Movement (Morena). This phenomenon, intensified after Andrés Manuel López Obrador’s electoral victory in 2018, represents the mass migration of a political elite that—having been shaped within the culture of tricolor hegemony—found in the so-called Fourth Transformation project a new space for professional viability and electoral survival. Analyzing this shift requires a deep look that goes beyond the superficial «grasshopper jumping» and delves into the transfer of territorial networks, operational know-how, and patronage structures that the PRI perfected over more than seventy years of near-absolute control over national public life.
The origin of this migration isn’t linear. It shows up in different geological layers of Mexican politics: from the historic cadres who broke with the PRI in 1988 to form the Democratic Current, all the way to the governors and senators who abandoned the tricolor ship in 2024, facing the inevitability of a new six-year term dominated by the ruling party. This investigation details, level by level, the presence of PRI genetics in Morena’s veins, emphasizing that the federal government’s chain of command, the legislative chambers, and state governorships are now made up—in significant proportion—of figures whose ideological and operational training was forged in the party they now claim to be fighting.
The Presidential Figure: The Genome of Revolutionary Nationalism
Andrés Manuel López Obrador is simultaneously the harshest critic of the «neoliberal period» and one of the most prominent heirs of the PRI’s political culture from the 1970s. His entry into the party in 1976 wasn’t accidental; it happened during poet Carlos Pellicer’s Senate campaign in Tabasco, at a time when the PRI represented the only path to institutional participation in the country. During his time as a member, López Obrador rose to become president of the PRI’s State Executive Committee in Tabasco and held positions in the Tabasco Indigenous Institute and at PROFECO, absorbing a statist and nationalist vision that defines much of his current government agenda.
López Obrador’s departure from the PRI in 1988, joining Cuauhtémoc Cárdenas’s National Democratic Front, marked the beginning of a thirty-year journey toward power, but it didn’t eliminate his pragmatism when it came to incorporating former PRI cadres into his movement. Since founding Morena in 2014, the president has operated under the premise that «political redemption» is possible for those who, having served the previous regime, decide to join the transformation—which has facilitated the entry of thousands of militants from every rank.

The Federal Cabinet: Operational Experience and Institutional Bridges
The formation of López Obrador’s cabinet in 2018 was a testament to his willingness to integrate technocratic and operational PRI elites. The presence of figures like Esteban Moctezuma Barragán—who was a key player in Ernesto Zedillo’s government—sent a message of stability to markets and the traditional bureaucracy. Moctezuma, shaped in the PRI of the 1970s, brought an institutional vision that was essential in the early years of the Ministry of Public Education before being sent as ambassador to Washington.
Another emblematic case is Marcelo Ebrard Casaubón, whose career was built under the wing of Manuel Camacho Solís in the PRI of the Federal District. Ebrard, secretary general of the PRI in Mexico City in 1992, represents the reformist wing that—after being pushed out by Carlos Salinas’s group—moved to the left, always maintaining a network of contacts and political sophistication inherited from his years in the tricolor. His role as Secretary of Foreign Affairs and later as a central figure in the 2024 internal race underscores the relevance of cadres with PRI origins in the movement’s strategic decision-making.
The Ministry of the Interior has also been a consolidation space for former PRI members. Adán Augusto López Hernández, whose membership in the Tabasco PRI lasted 25 years, became the president’s go-to political operator, using the negotiation and territorial control tools from his original training to keep governors and legislators in line.

The Legislative Branch: The 25-Senator Caucus and the Operational Bloc
In the Senate, the influence of PRI political culture is glaring. An estimated 25-plus members of Morena’s caucus in the LXIV and LXV legislatures have direct roots in the PRI. This group isn’t homogeneous; it ranges from regional leaders who control peasant and worker structures to former cadres from the foreign service and financial administration. The majority leader for much of the six-year term, Ricardo Monreal Ávila, is the clearest example of this transition. Monreal, who was a PRI member from 1975 to 1998, serving as a deputy and senator for the tricolor, knows the unwritten rules of Mexico’s system intimately, which allowed him to put together supermajorities by negotiating with his former party colleagues.
The transvasement has continued even after Morena’s consolidation. In 2023 and 2024, the PRI’s internal crisis under Alejandro Moreno Cárdenas’s leadership caused an exodus of high-profile senators who—under the banner of the «Progressive Alliance»—joined the ruling party’s project. Figures like Alejandro Murat Hinojosa (former governor of Oaxaca), Eruviel Ávila (former governor of the State of Mexico), and Jorge Carlos Ramírez Marín (a PRI pillar in Yucatán) formalized their support for Claudia Sheinbaum’s candidacy, bringing with them decades of legislative experience and electoral mobilization networks.

The Governors: Taking Over Tricolor Strongholds
Morena’s expansion across Mexico’s state map has largely been achieved by running «grasshopper cadres» who already had their own structures within the PRI. Of the 23 governorships that Morena currently controls, a significant percentage are led by politicians who spent decades in the tricolor’s ranks before switching to the López Obrador movement.
Hidalgo is perhaps the most dramatic case. For 93 years, the state was governed uninterrupted by the PRI, becoming the ultimate symbol of the old regime’s stability. However, in 2022, Morena won the governorship with Julio Menchaca Salazar—a man who was a PRI member from 1980 to 2015, serving as a magistrate and local deputy under the tricolor banner. Menchaca’s victory didn’t represent the defeat of Hidalgo’s elite, but rather their pragmatic relocation under new party labels.
In the north, Alfonso Durazo Montaño recovered Sonora for Morena after having served 21 years in the PRI, where he became a figure close to Luis Donaldo Colosio. His ability to bring together local political groups—many of them PRI-rooted—was key to his victory and the subsequent stability of his administration. In Sinaloa and Nayarit, governors like Rubén Rocha Moya and Miguel Ángel Navarro Quintero also have long histories in the traditional political system, which has allowed them to navigate the complex waters of regional politics with tools learned from the «old school.»

Municipal Dynamics and Territorial Control
The municipal level is where the transvasement from PRI to Morena becomes most granular and operational. To win mayorships in rural and suburban areas, Morena has systematically resorted to co-opting PRI precinct leaders and mayors who guarantee control of local «machines.» In states like Mexico, Guanajuato, and Oaxaca, a mayor’s migration from PRI to Morena usually brings along their entire slate of council members and public works directors—ensuring the electoral machinery stays intact despite the change in color.
In Mexico City, the case of Adrián Rubalcava in Cuajimalpa is telling. Rubalcava, who built a PRI stronghold in one of the capital’s most contrasting areas, broke with the party in 2023 after not being considered for the Head of Government candidacy. His integration into Claudia Sheinbaum’s platform gave Morena an electoral base that had traditionally eluded them, showing that local cadres’ loyalty is usually more tied to the survival of their power networks than to strict ideological principles.

Structural Analysis of the 2024 Migration: The «Progressive Alliance»
The most recent and perhaps most cynical phenomenon of this transition is the formation of the «Progressive Alliance» in late 2023. This group, made up of former governors, senators, and deputies who until just months earlier defended the PRI’s brand, announced their full support for Morena not because of programmatic alignment, but as a response to the «closed-mindedness» of the national leadership headed by Alejandro Moreno.
This movement is key to understanding the supermajority in Congress. The addition of figures like Eruviel Ávila and Alejandro Murat not only brings votes but also dismantles the last command structures the PRI had left in strategic states like the State of Mexico and Oaxaca. For Morena, the cost of bringing in these figures—frequently accused of corruption by the movement itself in earlier years—is offset by the elimination of effective competition and the consolidation of a predominant-party regime.
The cadre migration rate can be modeled under game theory logic, where the incentive to stay in a shrinking opposition party is infinitely smaller than the incentive to join a ruling coalition with access to resources and institutional protection. Mathematically, the probability of defection P(d) increases as the electoral capital of the party of origin C_o decreases and the power of the receiving party C_r increases:
P(d) = f(1/C_o, C_r) × I
Where I represents institutional inertia. In the PRI’s post-2018 case, C_o has reached historic minimums, making defection a rational behavior for the political elite.
The Impact on Morena’s Identity and Future
The massive integration of former PRI members raises deep questions about Morena’s identity. While the official discourse remains one of breaking with the past, the operational reality shows a continuity of PRI-style politics: corporatism, clientelism, and presidential centralism. The transvasement has allowed Morena to inherit the «governability» that the PRI once offered, but at the price of diluting its reformist and social-democratic profile.
As the PRI heads toward possible electoral irrelevance, Morena is consolidating as the new «big Mexican party»—an umbrella that shelters old elites under a new narrative. The story of the coming years will largely be the story of how these PRI-origin cadres fight for internal control of Morena against the ideological founders from the left, in a struggle to define the direction of presidential succession and regime consolidation.
Conclusions
This research reveals that the metamorphosis of Mexico’s party system has been more of an elite recycling process than a replacement. From Andrés Manuel López Obrador himself to the senators who joined in 2024, the common thread of national politics remains the DNA of the Institutional Revolutionary Party. Morena has proven to be an extremely efficient vehicle for relocating this political class, guaranteeing a power transition that—while rhetorically noisy—maintains the fundamental command and control structures that have characterized the Mexican state for the last century.
The membership matrix presented here is an X-ray of this change of skin: an elite that doesn’t disappear, but rather transforms itself to persist in the exercise of power under the emblem of hope and national regeneration.
