Chen Shui-bian
Democratic Progressive Party
Known for his advocacy of independence, Chen recently softened his nationalist campaign talk and now promotes building closer trade ties with mainland China. He says he would seek independence only if China invades.
"I promise I will not bring Taiwan to the brink of war," he pledges.
Like fellow presidential contender Lien Chan, Chen supports establishing shipping links with China and possibly later lifting restrictions on direct flights to the mainland. He says he would consider allowing Taiwan banks to open branches in China.
As mayor of the capital Taipei from 1994 to 1998, Chen gained a reputation of being tough on corruption. He also became known for his media stunts, which included surprise visits with TV crews to government offices to look for officials taking unauthorized days off.
Once a maritime lawyer, Chen made his name defending political dissidents during Taiwan's martial law era, which ended in 1987. Frustrated by seeing his clients repeatedly convicted by the state, Chen entered politics as a Taipei city councilor in 1981 and was elected to the Legislative Yuan, or parliament, in 1989.
