The government of Argentina, within the framework of a federal system, is a presidential representative democratic republic. The President of Argentina is both head of state and head of government. Executive power is exercised by the President. Legislative power is vested in the National Congress. The Judiciary is independent from the Executive and from the Legislature, and is vested in the Supreme Court and the lower national tribunals.
The Chamber of Deputies, officially the Honorable Chamber of Deputies of the Argentine Nation, is the lower house of the Argentine National Congress. It is made up of 257 national deputies who are elected in multi-member constituencies corresponding with the territories of the 23 provinces of Argentina by party list proportional representation. Elections to the Chamber are held every two years, so that half of its members are up in each election, making it a rare example of staggered elections used in a lower house.
The Honorable Senate of the Argentine Nation is the upper house of the National Congress of Argentina.
At the national level, Argentina elects a head of state and a legislature. The franchise extends to all citizens aged 16 and over, and voting is mandatory for all those who are between 18 and 70 years of age.
Most Provinces of Argentina held executive and legislative elections during 2011, electing governors and provincial legislatures. The only exceptions are Santiago del Estero Province, whose executive and legislative elections were elected in 2012; and Corrientes Province, whose gubernatorial election took place in 2013.
The Chamber of Deputies of Buenos Aires Province is the lower house of the Legislature of Buenos Aires Province, the largest and most populous of Argentina's provinces. It is made up of 92 deputies elected in eight multi-member constituencies known as Electoral Sections. The number of deputies that correspond to each of the electoral sections is proportional to their population, as observed in the results of every nationwide census conducted in Argentina every 10 years. Seats may only be added to adjust the proportionality of each section, but never reduced.
