About the election Short description of the context and results of the election.
President Mauricio Macri's "Let's Change" (Cambiemos) coalition (see note) increased its share of seats in both chambers of Congress but fell short of a majority. It holds over 100 seats in the 257-member Chamber of Deputies and 24 seats in the 72-member Senate. The coalition won in the traditional stronghold of Peronist forces, including Buenos Aires province and Santa Cruz. Former President Cristina Fernandez de Kirchner formed the Citizens' Unity (Unidad Ciudadana) party and was elected to the Senate. Following the elections, Peronist senators who distanced themselves from Ms. Fernandez de Kirchner (known as "Peronismo no K") formed a new parliamentary group, Justicialista, comprising 25 senators and 30 deputies. During the election campaign, the "Let's Change" coalition promised to continue its free-market reform agenda to revive the country's economy. Citizens' Unity argued that the government's policies have increased poverty and inequality in Argentina. Note: The "Let's Change" coalition included PRO (Republican Proposal), the Radical Civic Union (U.C.R.) and the Civic Coalition, amongst others.
