Su Tseng-chang

Su Tseng-chang, born on July twenty-eighth, nineteen forty-seven, is a prominent Taiwanese politician and lawyer, known for his significant contributions to the Democratic Progressive Party (DPP). He served as the premier of the Republic of China (Taiwan) from two thousand six to two thousand seven and again from two thousand nineteen to two thousand twenty-three, making him the longest-serving Democratic Progressive premier in history.

In two thousand five, Su held the position of chairman of the DPP and returned to this role from two thousand twelve to two thousand fourteen. His political journey includes serving as Chief of Staff to President Chen Shui-bian in two thousand four, alongside other notable politicians, forming what is known as the 'Big Four of the Democratic Progressive Party'.

Su's political ambitions have seen him actively campaign for the DPP presidential nomination in two thousand eight, where he finished second to Frank Hsieh. He later teamed up with Hsieh as the vice presidential nominee, although the DPP ultimately lost to the Kuomintang ticket. In two thousand ten, he ran for Taipei City Mayor but was defeated by the incumbent, Hau Lung-pin.

In two thousand eleven, Su campaigned for the DPP presidential candidacy again but lost to Tsai Ing-wen by a narrow margin. Following Tsai's loss to Ma Ying-jeou, Su was elected to succeed her as DPP chairman in two thousand twelve. His charismatic campaigning style earned him affectionate nicknames such as 'Lightbulb' and 'Go Go Go' from the Taiwanese media and DPP supporters.
