Piñera ran for President of Chile in the 2009–2010 election. Since August 2009, he led in opinion polls, competing with Eduardo Frei Ruiz-Tagle, Marco Enríquez-Ominami and Jorge Arrate; all of whom are left-of-center candidates. On 13 December 2009 election, Piñera placed first in the results with 44.05% of the votes, while Frei placed second with 29.6% of the votes. Neither candidate received more than half of the total votes; therefore, according to the Constitution, Chileans returned to the polls for a final run-off election on Sunday, 17 January 2010.
