General Information

At stake in this election:

  • 19 seats in the Senate (Senado)

Description of government structure:

  • Chief of State: President Sebastian PIÑERA
  • Head of Government: President Sebastian PIÑERA
  • Assembly: Chile has a bicameral National Congress (Congreso Nacional) consisting of the Senate (Senado) with 38 seats and the Chamber of Deputies (Camara de Diputados) with 120 seats.

Description of electoral system:

  • In the Senate (Senado) 38 members are elected through a closed party-list majority system to serve 8-year terms. Chile uses a binomial closed-list system, with 19 two-member districts in the Senate. Each electoral bloc (coalition or independent party) proposes 2 candidates per district. If the bloc that achieves a plurality obtains more than twice as many votes as the runner-up, it is awarded both seats. Otherwise, 1 seat is awarded to the candidate with the most votes in the most successful bloc, and 1 is awarded to the candidate with the most votes in the runner-up bloc. Half of the Senate stands for re-election every 4 years.
