The Argentine Constitution of 1853 mandates a separation of powers into executive, legislative, and judicial branches at the national and provincial level. The political framework is a federal representative democratic republic, in which the President is both head of state and head of government, complemented by a pluriform multi-party system.

Executive power resides in the President and the Cabinet. The President and Vice President are directly elected to four-year terms and are limited to two terms. Cabinet ministers are appointed by the President and are not subject to legislative ratification. The current President is Cristina Fernández de Kirchner, with Julio Cobos as Vice President.

Legislative power is vested in the bicameral National Congress, comprising a 72-member Senate and a 257-member Chamber of Deputies. Senators serve six-year terms, with one-third standing for re-election every two years. Members of the Chamber of Deputies are elected to four-year terms by a proportional representation system, with half of the members standing for re-election every two years. A third of the candidates presented by the parties must be women.

The judiciary is independent of the executive and the legislature. The Supreme Court has seven members appointed by the President in consultation with the Senate. The judges of all the other courts are appointed by the Council of Magistrates of the Nation, a secretariat composed of representatives of judges, lawyers, the Congress and the executive.

Though declared the capital in 1853, Buenos Aires did not become the official Capital until 1880. The 1994 amendment of the Argentine Constitution included a limited form of devolution to Buenos Aires. The national government reserved control of the Argentine Federal Police (the federally-administered city force), the Port of Buenos Aires, and other faculties, however.

Argentina is divided into twenty-three provinces (provincias; singular provincia) and one Autonomous City. Buenos Aires Province is divided into 134 partidos, while the remaining Provinces are divided into 376 departments (departamentos).

Departments and Partidos are further subdivided into municipalities or districts. With the exception of Buenos Aires Province, the nation’s provinces have chosen in recent years to enter into treaties with other provinces, forming four federated regions aimed at fostering economic integration and development: Center Region, Patagonic Region, New Cuyo Region, and the Argentine Greater North Region.
