[2] In September 1988, Peping Cojuangco, a stalwart of PDP–Laban, recruited national and local politicians allied with former President Ferdinand Marcos and Kilusang Bagong Lipunan (KBL) into the party.

[8] Ramos was backed by President Corazon Aquino while Mitra, who placed fourth, had the support of the late Manila Archbishop Jaime Sin.

In 1997, Raul Roco and Gloria Macapagal Arroyo, two of LDP's Senate stalwarts, resigned from the party and formed their own political organizations.

[10] Arroyo, however, was convinced by Jaime Cardinal Sin to discontinue her presidential plans and run for vice president as the running-mate of Lakas presidential standard-bearer Jose de Venecia Jr.[11] The LDP, now led by Edgardo Angara, formed a coalition with PDP–Laban, Pwersa ng Masang Pilipino and the Nationalist People's Coalition to form Laban ng Makabayang Masang Pilipino.

[13] In the 2004 elections, LDP was critically divided into two factions: the Angara wing led by Senator Edgardo Angara that supported the presidential bid of actor Fernando Poe Jr., and the Aquino wing led by Makati representative Agapito Aquino that supported the presidential campaign of Senator Panfilo Lacson.

With no signs that the two feudimg factions would come to an agreement, the Commission on Elections decided to informally split LDP into the Aquino and Angara wings.

[22] For the presidential and vice-presidential elections, LDP supported the Nacionalista–NPC ticket of Angara's Senate colleagues Manny Villar and Loren Legarda.

[23][24] Villar lost to Liberal Party's Benigno Aquino III, while Legarda trailed in the vice presidential race which was won by PDP–Laban's Jejomar Binay.

In early 2016, party president Angara initially expressed LDP's intention to support the independent presidential campaign of Grace Poe for 2016.

[29] On September 24, 2018, Sonny Angara was elected as LDP president at an organizational meeting and fellowship dinner held at the Manila Golf and Country Club.

[31] In 2021, Sonny Angara eyed a national alliance with HNP, as Sara Duterte was poised to run for president due to her strong performance in pre-election surveys.
