2010 Philippine presidential election

The 2010 Philippine presidential and vice presidential elections were held on Monday, May 10, 2010. The ruling President of the Philippines, Gloria Macapagal Arroyo, was ineligible to seek re-election as per the 1987 Constitution, thus necessitating an election to select the 15th President.

Incumbent Vice-President Noli de Castro was allowed to seek re-election, though he could have possibly sought the presidency. As he didn't offer himself in any manner of candidacy at the election, his successor was determined as the 13th Vice President of the Philippines. Although most presidential candidates have running mates, the president and vice president are elected separately, and the winning candidates may be of different political parties.

This election was also the first time that the Commission of Elections (COMELEC) implemented full automation of elections, pursuant to Republic Act 9369, "An Act Authorizing The Commission on Elections To Use An Automated Election System In The May 11, 1998 National or Local Elections and In Subsequent National And Local Electoral Exercises".

The results of the congressional canvassing showed that Senator Benigno Aquino III of the Liberal Party won by a plurality, although he had won with the highest percentage of votes since 1986, but not enough to have the largest margin of victory, even in elections held after 1986.

Meanwhile, in the election for the vice-presidency, Makati Mayor Jejomar Binay of the Partido Demokratiko Pilipino-Lakas ng Bayan (PDP-Laban) defeated Senator Mar Roxas of the Liberal Party in the third-narrowest margin in the history of vice presidential elections. Aquino and Binay were proclaimed in a joint session of Congress on June 9, and took their oaths on June 30, 2010. Roxas filed an electoral protest to the Presidential Electoral Tribunal (PET; the Supreme Court) on July 10, 2010.
