General elections were held in the City of Buenos Aires on 22 October 2023, coinciding with the general election being held nationwide. The Chief of Government (mayor), half of the City Legislature and all 150 members of the communal boards were elected to four-year terms.
In the mayoral election, Jorge Macri, of the ruling PRO party, won in the first round of voting with 49.67% of the vote. According to the city's constitution, a candidate for Chief of Government must achieve over 50% of the vote in order to win in the first round, but the second-most voted candidate, Leandro Santoro of Union for the Homeland, dropped out of the race for the second round and ceded victory to Macri.
This was the seventh general election in the City of Buenos Aires since the adoption of the 1996 Constitution, which granted autonomy to the city and allowed it to vote for its own Chief of Government. It was also the second election in which the Single Electronic Ballot (Boleta Única Electrónica, BUE) voting system was implemented, after 2015.
The 2019 elections in Buenos Aires had resulted in the re-election of incumbent Chief of Government Horacio Rodríguez Larreta with a record 55.90% of the vote in the first round. Rodríguez Larreta's party, Republican Proposal (PRO) and its Juntos por el Cambio alliance also remained the largest force in the City Legislature. [1]
On 13 April 2023, Rodríguez Larreta issued a decree making the 2023 elections in Buenos Aires concurrent with the national general election. [2] Rodríguez Larreta was constitutionally barred from running for re-election a second time, and instead launched his presidential run. [3]
This was the second election in which the Single Electronic Ballot (Boleta Única Electrónica, BUE) voting system was implemented, after 2015. It was, however, the first time the BUE system was implemented in a local election concurrent with a national election, which meant two different voting systems were used in the same election day.
