Ju Gau-jeng

Ju co-founded the Democratic Progressive Party in 1986, and was responsible for writing the party charter. He was elected to the Legislative Yuan for the first time that year. Shortly after taking office, Ju gained the nickname Rambo for his combative personality, which frequently led to him physically fighting other lawmakers. Ju ran for election in 1989 without the support of the Democratic Progressive Party, and managed to retain his legislative seat. For mounting an independent campaign, Ju was expelled from the DPP in February 1990 and founded the Chinese Social Democratic Party in 1991. He contested the 1992 legislative elections as a CSDP candidate, which he won. As the only member of his party, Ju chose to caucus with the New Party. By 1993, Ju had again decided to switch affiliations. Though he briefly considered joining the Kuomintang, he was named the New Party candidate for governor of Taiwan Province in August 1994. As a result, Ju consolidated the CSDP with the New Party on 28 December 1994. He lost the gubernatorial election to incumbent James Soong, but subsequently was reelected to parliament as a member of the New Party in 1995. Ju was expelled from the New Party in 1997, and not reelected as an independent candidate in the 1998 legislative election. Ju and Hsu Hsin-liang created the Tangwai round-table forum in February 2003. After his retirement from politics, Ju taught law at Peking University.
