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.
