Entry into politics

Macias’ entry into politics started when he was elected as one of the delegates to the 1971 Constitutional Convention, the body that drafted the 1973 Constitution of the Philippines. In 1975, he acquired a post in the Provincial Council in the Province of Negros Oriental, and was subsequently elected as Vice-Governor in 1980. From 1984 to 1986, he was one of the delegates representing Negros Oriental to the Regular Batasang Pambansa as a member of Kilusang Bagong Lipunan, then the ruling party during the administration of President Ferdinand Marcos. From 1985 to 1986, he served as Deputy Health Minister of the then Ministry of Health.^[3]

Macias was elected Governor in 1988 and continued to hold on to the post for three consecutive terms until 1998. After the expiration of his term, he ran for Congress and was elected as a Representative of the 2nd District of the Province. He served for three consecutive terms until 2007 when in the same year he was again elected as Governor of the Province. In the 2010 May elections, Macias won a second term but died of liver cancer before taking his oath of office.^[2][4] His body was cremated and the ashes flown to Dumaguete where a three-day wake was held in the Provincial Capitol. His ashes were subsequently brought to the Municipality of Siaton, Macias' hometown.^[5]

Macias was succeeded in office by outgoing vice governor Jose Baldado in an interim capacity for the remainder of his term until then vice governor-elect Agustin Perdices took office.
