LONDON — The political landscape in Argentina is bracing for a significant structural shift as the administration of President Javier Milei intensifies its push to overhaul the nation’s electoral framework. At the heart of this contentious debate is the potential elimination of the Primarias Abiertas, Simultáneas y Obligatorias (PASO)—the mandatory, open, and simultaneous primary elections that have defined Argentine politics for over a decade.
The movement to dismantle the current system is gaining momentum, fueled by a potent combination of fiscal austerity arguments and a desire to reshape the country’s political competition. Leading the charge in recent discussions is Diego Santilli, a prominent political figure, who has underscored the massive economic burden these elections place on the public treasury. Santilli has asserted that the current primary system costs Argentine citizens approximately $250 million, framing the reform not merely as a political maneuver, but as a necessary measure of economic responsibility.
As the Milei administration seeks to implement its “chainsaw” approach to state spending, the debate over the PASO has become a litmus test for the government’s ability to navigate the complex relationship between the federal executive and provincial governors. While the administration views the reform as a way to streamline democracy and reduce waste, critics and provincial leaders warn of potential disruptions to local political stability and the loss of a mechanism designed to ensure broad-based political participation.
The Economic Argument: The $250 Million Question
The primary catalyst for the current push to reform the electoral system is the staggering cost associated with organizing national primary elections. In a country grappling with significant inflation and a rigorous fiscal adjustment program, the expenditure required to facilitate the PASO has become an easy target for the Milei administration. By framing the elections as a drain on public resources, the government is attempting to align electoral reform with its broader mandate of reducing the state’s footprint.

Diego Santilli’s recent statements have brought this figure to the forefront of the national conversation. By citing the $250 million cost, proponents of the reform are appealing to a public that is increasingly sensitive to government spending. The argument suggests that the resources currently diverted to these massive, synchronized voting events could be better utilized in areas of direct social or economic relief. For the Milei administration, eliminating the PASO is a logical extension of its commitment to fiscal discipline.
However, the complexity of calculating these costs cannot be understated. The figure of $250 million encompasses a wide range of expenditures, including the logistics of nationwide polling stations, the printing of millions of ballots, the staffing of electoral bodies, and the massive security apparatus required to oversee the process. While the administration argues these costs are redundant, opponents suggest that the primary system provides a unique value in vetting candidates and preventing political fragmentation during the general election.
Understanding the PASO: A Pillar of Argentine Democracy
To understand why the elimination of the PASO is so controversial, one must first understand the mechanism itself. Established under Law 26.569, the Primarias Abiertas, Simultáneas y Obligatorias were designed to modernize the Argentine electoral process. Before their implementation, political parties often selected candidates through internal, closed-door processes that were frequently criticized for being opaque and prone to factionalism.
The PASO system introduced three critical elements:
- Open (Abiertas): Any citizen registered to vote can participate in the primaries, regardless of their formal affiliation with a specific political party. This allows for a broader range of voices to influence the selection of candidates.
- Simultaneous (Simultáneas): All political parties hold their primary elections on the same day across the country, creating a unified electoral calendar.
- Mandatory (Obligatorias): Participation is required by law for all eligible voters, ensuring that the primary results carry significant democratic weight.
The intended benefit of the PASO was to “cleanse” the political field, ensuring that only the most viable and widely supported candidates move forward to the general election. By forcing parties to compete in a public arena, the system was meant to increase transparency and accountability. However, critics argue that the mandatory nature of the vote forces citizens to participate in political processes they may find irrelevant, and that the high cost of the simultaneous nationwide vote is an inefficient way to achieve these democratic goals.
The Political Chessboard: Governors and the Federal Tension
The push to reform the PASO is not occurring in a vacuum; it is unfolding against a backdrop of intense friction between the Casa Rosada and Argentina’s provincial governors. In the Argentine federal system, governors wield significant power, often acting as the primary interlocutors between their provinces and the central government. Many of these leaders rely on the current electoral framework to maintain their local political structures and influence.

The debate over the PASO has become a proxy for a larger struggle over political autonomy and the distribution of federal funds. Some governors view the central government’s attempt to alter the electoral rules as an encroachment on provincial sovereignty. The political impact of eliminating the primaries varies wildly by region. In provinces where traditional political machines are well-established, the PASO serves as a vital mechanism for consolidating power and managing internal party disputes.
The tension is exacerbated by the internal dynamics within the libertarian movement itself. As President Milei’s La Libertad Avanza party seeks to expand its reach, the way in which candidates are selected and presented becomes a matter of intense internal debate. The relationship between the presidency and the governors will likely determine whether the proposed electoral reforms can successfully navigate the legislative hurdles in the Argentine Congress.
Winners and Losers: The Impact of Reform
If the government succeeds in eliminating or significantly altering the PASO, the political landscape of Argentina will undergo a profound transformation. The shift will create distinct “winners” and “losers” among the various political factions, fundamentally changing how power is contested and consolidated.
Potential Winners
Newer Political Movements: For emerging parties and “outsider” movements, the current PASO system can be a double-edged sword. While it provides a platform to reach a wide audience, the high barrier of entry and the need for massive logistical support can favor established parties. A move toward optional or less formal primaries could allow newer movements to consolidate their bases more efficiently without the massive overhead of a national primary.
Established Political Machines: Paradoxically, large, well-funded political organizations may also benefit. Without a mandatory, open primary to vet candidates, these parties may regain more control over their internal selection processes, allowing them to present “pre-approved” candidates in the general election, thereby reducing the risk of unexpected upsets.
Potential Losers
The Electorate and Political Transparency: The most significant “loser” in many analysts’ views would be the transparency of the democratic process. The elimination of open primaries could lead to a “closed-door” style of politics where candidates are chosen by party elites rather than the broader citizenry. This could lead to a decrease in political engagement and a sense that the electoral process is less representative of the public will.
Political Diversity: The PASO system, despite its flaws, allows for a diversity of candidates to emerge from within parties. Without this mechanism, the political field may become more predictable and less dynamic, as the ability for grassroots candidates to challenge established party leaders is diminished.
The Proposed Compromise: Optional Primaries
Recognizing the potential for intense legislative resistance, the Milei administration is reportedly considering a middle-ground approach. Rather than a total abolition of the primary system, some policymakers are suggesting the implementation of optional primaries. Under this model, the state would no longer mandate a nationwide, simultaneous election. Instead, individual political parties would have the autonomy to decide whether they wish to hold their own primaries to select candidates.
This “optative” model would address the government’s primary concern regarding fiscal waste, as the cost of organizing these elections would shift from the state to the individual political parties. It would also respect the autonomy of political organizations, allowing them to maintain their preferred selection processes. However, this compromise would also raise new questions about electoral equity, particularly regarding how smaller parties with fewer resources would compete against larger organizations that can afford their own internal voting processes.
Key Takeaways
- The Fiscal Driver: The Milei administration is using the $250 million cost of the PASO as a central argument for electoral reform.
- The Core Conflict: The reform pits the central government’s austerity goals against the political interests and sovereignty of provincial governors.
- Systemic Change: Eliminating the PASO would move Argentina away from its current “open and mandatory” primary model toward a potentially more fragmented or party-controlled system.
- The Compromise: A shift toward “optional” primaries is being discussed to balance cost-cutting with political autonomy.
Conclusion and Next Steps
The battle over Argentina’s electoral rules is far from over. The proposal to eliminate the PASO represents a fundamental challenge to the country’s democratic architecture, touching on issues of fiscal responsibility, political transparency, and federalism. As the Milei administration continues to press its agenda, the coming months will be critical in determining whether these reforms can secure the necessary legislative support or if the political friction with provincial leaders will stall the initiative.
The next significant checkpoint in this developing story will be the upcoming legislative sessions in the Argentine Congress, where the specific details of the electoral reform bill—whether it proposes total abolition or a move toward optional primaries—will be formally debated and contested. Observers should watch for the official presentation of the reform package and the subsequent reactions from the various provincial governorships.
