Raul Daza

In 1969 Daza was elected congressman representing the Lone District of Northern Samar for one term until the declaration of Martial Law.

After the House of Representatives was abolished by President Ferdinand Marcos, Daza and his family went to the United States.[3]

In the U.S. Daza led opposition groups from his residence in Los Angeles, California.[4]

In August 1985, President Marcos stated Daza and other opponents living abroad may return to the Philippines but "must face any charges against them." Daza returned to the Philippines the following week with 14 other opposition leaders. Upon arrival Daza told reporters "Our motherland is in her darkest hour... the time has come for all true Filipinos, whether here or abroad, and regardless of class, calling or roots, to rally around her." At arrival he faced charges of subversion, arson and homicide in connection with his alleged involvement with the rebel "Light-A-Fire-Movement." Former Senator Jovito Salonga, who had returned earlier that year, told reporters that Daza would play a key role in organizing the Liberal Party for the elections.[4]

In 1986, he was appointed by Corazon Aquino as Deputy Minister of the Presidential Commission on Good Government until 1987 when he announced his candidacy as Representative of First District of Northern Samar.

After the restoration of the House of Representatives but in a new location at the Batasang Pambansa Complex, he ran for the First District of Northern Samar.

During the opening of the 9th Congress, he was eventually elected as Speaker Pro Tempore succeeding Antonio Cuenco. By 1995, he became Deputy Speaker for Visayas until 1998. He also became the President of Liberal Party in 1994 succeeding Wigberto Tanada. He held that position until 1999.

After his tenure as congressman, he was appointed Commissioner of the Presidential Commission on Constitutional Reforms from 1999 to 2000. In 2001, he won as governor of Northern Samar. He was re-elected in 2004 and 2007.

He was elected congressman again in 2010 and regained his seat from his son Paul after he swapped places with the latter. In 2013, he lost his congressional seat to Harlin Abayon. In 2016, he regained the seat from Abayon after the latter was disqualified by the House of Representatives Electoral Tribunal. This was reversed by the Supreme Court, but speaker Feliciano Belmonte Jr. did not heed the court's decision and paved way for Daza's return. During his return as congressman, he was part of the minority at age 82 after President Rodrigo Duterte's party PDP–Laban gained a supermajority in the House of Representatives.
