The Lingayen-Lucena corridor is the part of Luzon in the Philippines, between Lingayen (in Pangasinan) to Lucena, comprising the province of Pangasinan, and the regions of Central Luzon, Metro Manila and CALABARZON, where national elections are claimed to be won. The corridor comprises about 40% of the vote.
Between Lingayen in the north and Lucena in the southern part of Luzon is the part of the Philippines that is described as the most urbanized. This is where the high concentration of television and radio makes advertising in those mediums to be critical in winning votes.
Aside from being easily reached by candidates either via television or radio, it also has the highest number of internet connections, is the primary market of national dailies, and is the wealthiest area in the country. The corridor, which contains up to 40% of voters in the country, has been used as a sample in opinion polls to gauge how candidates are faring.
The voters in the corridor, which has been described as the so-called "market vote", was described in 2003 by Antonio Gatmaitan, political strategist for Eduardo Cojuangco, Jr.'s failed 1992 presidential bid, as the place where anyone can win, and if one can win there, he can win nationally. Market votes are votes which cannot be commanded by political kingpins; this is opposed to the so-called "command votes", which can be delivered by political kingpins.
In 2004, Gatmaitan introduced the corridor plus Naga, Legazpi, Cebu City, Bacolod, Iloilo City, Davao City, Cagayan de Oro and Zamboanga City which together comprises almost 52% of the voters.
