About the election

The Union for the Homeland (UP), the governing coalition led by Mr. Sergio Massa, became the largest force in both chambers of Congress following the 2023 elections. UP won 48 of the 130 seats at stake in the 257-member Chamber of Deputies, and holds 108 seats in all. Together for Change (JxC/Juntos), led by Ms. Patricia Bullrich, holds 94 seats, while “Freedom Advances” (LLA), led by Mr. Javier Milei, has 38 seats. The UP won the highest number of seats in 2023 (10 out of 24) in the 72-member Senate, holding 33 seats. Juntos became the second largest force with 21 seats, followed by LLA, which entered the Senate for the first time.

No candidate was elected in the first round of the presidential elections held in parallel with the parliamentary polls (see note). Mr. Massa (UP), a Peronist and former Minister of Economy, and Mr. Milei (LLA), former deputy and TV economic commentator, advanced to the run-offs. On 19 November, Mr. Milei, who defines himself as an anarcho-capitalist and anti-establishment candidate, won the run-off elections. On 10 December, Mr. Milei was sworn in as the new President of Argentina, succeeding President Alberto Fernández (UP).

Ms. Victoria Eugenia Villarruel (LLA) was sworn in as the new Vice-President (who is also the Senate President), succeeding Ms. Cristina Elisabet Fernández de Kirchner.

During election campaigning, the major parties focused on economic issues, such as inflation, dollarization (meaning Argentina would use US dollars as its currency instead of the peso), climate change and abortion rights.

Note :

To avoid a run-off election, presidential candidates need to obtain 45% of the vote, or 40% plus holding at least a 10% advantage over their nearest rival.
