# 2017 Argentine legislative election

Legislative elections were held in Argentina on 22 October 2017 to elect half of the Chamber of Deputies and one third of the Senate. The result was a victory for the ruling Cambiemos alliance, being the most voted force in 13 of the 24 districts.

## Background

The elections took place during the presidency of Mauricio Macri whose Cambiemos coalition also governed the City of Buenos Aires and Buenos Aires Province. As Cambiemos was a new coalition with few noteworthy political figures, several members of the cabinet were asked to resign from their positions and run for Congress in their respective districts instead.
Peronist factions were divided in two main groups; the Citizen's Unity, led by the former president Cristina Kirchner, led the parliamentary opposition to Macri's administration. Another group was composed of politicians from the Justicialist Party and the Renewal Front.

## Electoral system
### Chamber of Deputies

The 257 members of the Chamber of Deputies are elected by proportional representation in 24 multi-member constituencies based on the provinces (plus the City of Buenos Aires). Seats are allocated using the d'Hondt method with a 3% electoral threshold. In this election, 127 of the 257 seats are up for renewal for a four-year term.
