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.
