Chilean presidential election, 2009

The first round of the Chilean presidential election of 2009–2010 was held on Sunday December 13, 2009. Based on the two-round system, since none of the candidates secured the absolute majority needed to take the presidency outright, a run-off between the two most-voted candidates —center-right Sebastián Piñera and center-left Eduardo Frei Ruiz-Tagle— was held on Sunday, January 17, 2010. Piñera, who won the runoff with about 51.6% of the vote, succeeded Michelle Bachelet on March 11, 2010. Parliamentary elections took place on the same day.
