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.^[3]

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.^[4] Another group was composed of politicians from the Justicialist Party and the Renewal Front.^[5]
