Presidential elections in the Philippines

During the Philippine Revolution, several leadership elections for the Katipunan were later on described as precursors of presidential elections. One example of this is the Tejeros Convention of 1897, where Emilio Aguinaldo successfully removed erstwhile Katipunan leader Andres Bonifacio. From that point on, it was Aguinaldo who would lead the revolution, declare independence from Spain, and convened the Malolos Congress. The Malolos Congress elected Aguinaldo as president on January 1, 1899, passed a constitution on January 22, and Aguinaldo and the First Republic was inaugurated on January 23, 1899. The First Republic existed until Aguinaldo's capture by the Americans on March 23, 1901.

The first presidential election by popular vote was on September 15, 1935, after the ratification of the 1935 Constitution of the Philippines; Manuel Quezon of the Nacionalista Party emerged as the victor, defeating previous president Emilio Aguinaldo (Aguinaldo was elected president by the Malolos Congress). As a commonwealth then of the United States, the constitution decreed that the president shall have one term of six years without reelection. In 1940, it was amended to allow one reelection, but with the term shortened to four years; this setup was first used in the second election in 1941 with Quezon being reelected.

However, World War II intervened and thus suspended the elections of 1945. The Empire of Japan set up the Second Philippine Republic that elected José P. Laurel as president by the National Assembly in 1943. After the Japanese were defeated, Congress rescheduled the much-delayed election in 1946. Manuel Roxas of the newly formed Liberal Party won the election a few weeks prior to the granting of independence by the United States. In 1949, the first election for the newly independent republic was held with President Elpidio Quirino winning; Quirino succeeded Roxas, who died while in office. Thereafter, elections were held every four years every second Tuesday of November of the election year, with the winning president and vice president inaugurated on December 30 succeeding the election. The alternation between the Nacionalistas and the Liberals characterized an apparent two-party system of the Third Republic.

In the operation of the 1935 constitution, there were nine presidential elections; excluding the first election where there were no incumbents, the incumbent was beaten four times (1946, 1953, 1961, 1965), the incumbent won upon ascending to the presidency from a vacancy twice (1949, 1957), and two incumbents won a second term after being elected to a first term as president (1941, 1969).

In 1972, President Ferdinand Marcos declared martial law and ruled by decree. At this time, a new constitution was ratified in 1973 in which the office of the vice president being abolished. and that the president shall be elected by the National Assembly amongst themselves, although once elected, the president will cease to be a member of the National Assembly and any political party (similar to the British Speaker of the House of Commons). With the members of the National Assembly having no term limits, the president may serve indefinitely. In 1977, before parliament was elected, a presidential referendum affirmed that Marcos will stay as president and prime minister even after parliament has been organized.

In 1981, via constitutional amendment, the president is again elected via popular vote, with a term of office of six years starting at the thirtieth of June of the year of the election. In the succeeding election on June 16, 1981 (third Monday of June); Marcos was again elected, with much of the opposition boycotting the election. In addition, the amendment also renamed the National Assembly into its Filipino translation as "Batasang Pambansa." In 1984, another amendment reinstated the office of the vice president. The election of the vice president is similar to the United States presidential election, in which a vote for the president is also a vote for the vice president, although this was later changed to a separate vote for each position. Marcos' Kilusang Bagong Lipunan (New Society Movement or KBL) won every presidential election of the Fourth Republic until 1986.

In 1986, Marcos called for an early or "snap" election (the next scheduled election was in 1987) and was, including his running mate Arturo Tolentino, declared the winners. The People Power Revolution erupted that drove Marcos out of power, and Corazon Aquino, the runner-up, assumed the presidency. A new constitution was ratified in 1987 that was essentially identical with the provisions of the amended 1973 constitution as long as the election of the president and vice president is concerned, with the presidential election occurring at the second Monday of May and the inauguration every June 30 of the election year. The 1992 election was the first election under the new constitution and elections are held every six years thereafter. Fidel V. Ramos won the 1992 election with just 23% of the vote, the lowest plurality in history; it also ushered in the multi-party system of the Fifth Republic. Thereafter, no winner has won via a majority, although each has had an increasing percentage of votes with every succeeding election. Joseph Estrada won in 1998 in what was described as landslide, getting just under 40% of the votes, while second place Jose de Venecia getting 16%. President Gloria Macapagal-Arroyo, who succeeded Estrada at the outcome of the 2001 EDSA Revolution, was the first sitting president to run since 2006 and defeated Fernando Poe, Jr. in the closest margin in history. Benigno Aquino III won in 2010 with 42% of the vote in what was also called as a landslide, defeating Estrada who had 26% of the vote, and seven others. Rodrigo Duterte won with just under 40% of the vote, but with a 14% margin of victory from second-placer Mar Roxas in 2016.

In the operation of the 1987 constitution, incumbents who have in office for more than four years are barred to defend their seats, but all but one (1992) candidate endorsed by the incumbent lost, and one defended the seat after ascending to the presidency (2004).

Starting in 1941:

Every president who is eligible to run for president ran again, except in 1992 where Corazon Aquino did not run.

Vice presidents who became president upon vacancy of the latter office ran four times, and won as presidents in their own right in 1949, 1957 and 2004, and lost In 1946.

Starting in 1941:

• 1946, 1949, 1957: Erstwhile vice president became president after death of the previous president
• 1981: Office of the vice president did not exist at time of election
• 1986: No incumbent prior to election

Four vice presidents ran for the presidency after their vice presidential term ended. Two of them won, in 1961, beating the incumbent president, and in 1998. Two of them, in 1992 and in 2016, lost

Two vice presidents ran for another office after their vice presidential term ended; both won: in 1953, the vice president ran and won for senator, finishing first, and in 1965 where the vice president ran for a seat in the House of Representatives.

Two vice presidents defended the seat, with both succeeding in 1941 and 1969.

Two vice presidents did not pursue other office after their vice presidential term ended.
