His political career was marked as one of the most violent periods in the history of Cavite, which was at its height during the years of 1946–1955 in a bloody struggle with his long-time rival Justiniano Montano.

After World War II, he became governor, backing numerous presidential candidates under the Liberal Party during elections, resulting in an intense struggle with Montano and his supporters.

Camerino's adviser during this time as governor was Yoshiaki Muto, who was also the interpreter for General Masaharu Homma, and was responsible for saving the lives of many Filipinos from Japanese persecution.

[3] In 1946, Camerino, with his remaining influence backed the Liberal Party candidate Manuel Roxas, giving him a 27,000 vote margin.

[3] On 1 January 1953, an assassination attempt was made on Camerino's life at the Lyric Theater in Manila while watching a movie by Crispulo Colmenar, who was caught after being wounded by a bodyguard.

President Quirino called Camerino a day after as he was recovering in the Philippine General Hospital, making statements deploring the political violence in Cavite resulting in the assassination attempt.

However, the Supreme Court found no sufficient evidence to conclude that Camerino was involved in the crime and was acquitted on 26 June 1954 and affirmed 5 years later in 1959.

[4][9][8] After the death of Magsaysay on 17 March 1957, he was succeeded by Carlos P. Garcia, who showed compassion for Camerino and pardoned him for his suspected involvement in the electoral violence of 1953.

[4][11] On 25 April 1972, Cavite Vice Governor Dominador Camerino left his sickbed at the Makati Medical Center to take up the peace and order situation in his province and to renew his request for the release of funds for the repair of roads damaged by a series of typhoons.

[19][20] Additionally, during the term of Homer Saquilayan as City Mayor, two monuments dedicated to Camerino previously made by the Kapisanang Bagong Kaliwanagan were transferred to the municipal hall of Imus.

He was barely 16 when he was married to a barrio lass, Tomasa Cuello, by whom he begot three children; namely, Leonida, Lourdes, who died in infancy, and Rosa.

[1][3] On 29 August 1978, a movie titled 'Camerino' was released on the cinemas, which starred famous actor Ramon Revilla Sr., who was the main character of the film.
