What type of government does Argentina have?

Argentina is a federal presidential republic with 23 provinces and the Autonomous City of Buenos Aires. The president holds executive power and governs with a cabinet. The bicameral National Congress comprises the Senate and Chamber of Deputies.

Who is the current president of Argentina?

Javier Milei has been President of Argentina since December 2023. A libertarian economist, he won a decisive runoff against Sergio Massa with about 56% of the vote.

What are the main political parties in Argentina?

The main forces are La Libertad Avanza (Milei's libertarian party), Peronism/Justicialist Party (centre-left to left, historically dominant), and Juntos por el Cambio/PRO (centre-right opposition). Argentine parties frequently splinter and realign.

Peronism (based on Juan Peron's legacy) is Argentina's most enduring political movement, blending populism, labor rights, and nationalism. The Justicialist Party is its formal party vehicle. It has governed Argentina for most of the period since the 1940s.

What is Milei's agenda?

Milei's agenda centers on radical deregulation, dollarization debates, slashing public spending, closing government agencies, and liberalizing Argentina's economy. He governs as a minority president and has relied heavily on executive decrees.

The Presidency, Federalism, and the Peronist Machine

Argentina's constitution creates a federal presidential republic with twenty-three provinces and the Autonomous City of Buenos Aires. The president is directly elected for a four-year term with one possible consecutive reelection, and exercises broad executive powers including the ability to issue necessity and urgency decrees (decretos de necesidad y urgencia, or DNUs) that carry the force of law unless both chambers of Congress explicitly reject them. This decree power has been used aggressively by presidents of all ideological orientations — Menem, Kirchner, Macri, Fernández, and now Milei — and represents one of the most significant concentrations of executive authority in any presidential democracy. The practical effect is that Argentine presidents can govern by decree on economic policy, regulatory reform, and even institutional restructuring, with Congress serving as a reactive check rather than a proactive legislator.

Argentine federalism is formally robust but practically shaped by a profound fiscal imbalance: the national government collects most tax revenue and redistributes it to provinces through a revenue-sharing system (coparticipación) whose formula is a perpetual source of political conflict. Provincial governors are powerful political actors who control patronage, police forces, and local judiciaries, and who deliver or withhold legislative votes in Congress depending on their relationship with the president. This makes provincial politics — particularly in the Peronist heartland of Buenos Aires province — a critical site of power that national politics cannot bypass. The Justicialist (Peronist) Party is less a party than a political movement with organizational capacity that no rival has ever matched: its network of labor unions, social organizations, municipal operatives, and provincial machines gives it structural advantages in mobilization and governance that persist even when Peronism loses presidential elections.
