In 1969, he ran in Buriram as an independent candidate and managed to win. He was then reelected many times. In 2007 Chai was elected to the National Assembly of Thailand as a People's Power Party representative, however, he was previously affiliated with many political parties, including Justice Unity Party, Chart Thai Party, Solidarity Party and Thai Rak Thai.^[2][3]
