Javier Milei’s libertarian movement, La Libertad Avanza (LLA), has achieved a huge electoral breakthrough in the 2025 midterm legislative elections in Argentina, winning nearly 40% of the vote and securing about one-third of the lower house, and moving close to similar strength in the Senate. This highlights that this milestone gives Milei a level of legislative leverage he lacked earlier. Controlling a third of the Chamber of Deputies means opposition parties can no longer easily rely on veto majorities, which changes the game in Argentina’s Congress. The article outlines how Milei’s shock-therapeutic agenda, like cutting taxes and state size, easing labour laws, cutting union power, now has real odds of becoming enforced rather than only proposed. The article also mentioned the low voter turnout, around 68%, suggesting political disengagement, and comments on the decline of the long-dominant Peronism, which lost ground across nearly all provinces.
This shift matters because it signals a potential re-engineering of Argentina’s political state, a party that once commanded a small minority now holds structural power to push massive reforms. The change reflects voter frustration with crisis prone Peronist governments, inflation and state dysfunction. Historically, Argentina has operated under Peronist dominance and heavy state intervention, so Milei’s win marks a break with that legacy. The lasting impact may be significant, because if LLA turns legislative potential into enacted reforms, Argentina could drift sharply toward liberal economics and weaken union-state ties. On the other hand, mistakes might provoke social backlash, given the country’s history of political fragility.
Stakeholders include the Argentine government, Milei and LLA, the opposition Peronist parties, and the broader electorate. The government should capitalize on its mandate by forging alliances in Congress, articulating reform pathways and visibly delivering economic stabilization to justify its new power. The opposition must reassess strategy, rebuild grassroots legitimacy and offer credible alternatives rather than rely solely on tradition. Voters should monitor reform outcomes and hold their representatives accountable, ensuring the shift isn’t just rhetorical but delivers tangible improvement.
This event connects to IB Global Politics concepts, because the election victory shows a shift in structural power (LLA gains legislative leverage), and reflects a change in hard power (their ability to enact policy) and soft power (their political legitimacy) within Argentina. Milei’s movement is attempting to gain authority over the country’s political-economic order, moving away from the out-dated Peronist model. The low turnout signals weakened legitimacy and participatory power among citizens. The case illustrates how power isn’t just about winning votes but how the state must act on promises, and how a new majority can translate votes into governance, altering a nation’s power dynamics.
