Su Jia-chyuan, the opposition Democratic Progressive Party (DPP) mayoral candidate in the municipality of Taichung City, officially launched his campaign office in that central Taiwan city Sunday. He promised to conduct an honest campaign to win support by projecting his visions for the city rather than by trying to belittle his opponent. He expressed gratitude to DPP Chairwoman Tsai Ing-wen, who joined him in unveiling a name plaque for the office, saying that it was very kind of Tsai to take time off from her own campaign for mayor of Xinbei City to attend the opening of his campaign office. Su, a former DPP secretary-general, vowed to do his best to win the election and lead the central Taiwan city to compete with Xinbei City, which he said hopefully will be led by Tsai. Former Government Information Office Minister Lin Chia-lung, who agreed to serve as Su's campaign manager after an unsuccessful bid for his party's nomination in Taichung, said at the opening that Tsai did a great job in the selection process because Su is the party's best chance of winning the election. Tsai praised Lin as a promising DPP star who puts the interests of the party before his own. With Lin's help, Su's victory is assured, she said. She said that a scandal which exposed a close association between senior police officers and gangsters in Taichung cast a cloud over the city, but that Su, a former interior minister and Pingtung County magistrate, would work to ensure the safety of life in the city. In response, Su said that when he was magistrate of Pingtung County, he kept close tabs on the social order situation there and was always informed within one hour of any incidents, not after four days. He was referring the fact that his Kuomintang rival in the mayoral race, the incumbent Taichung Mayor Jason Hu, was not aware of the extent of the recent scandal until four days after it erupted. Although there are various DPP factions in Taichung, they have all rallied behind his candidacy, Su said. He promised to forbid his aides from engaging in any personal character attacks during the campaign. Also on Sunday, Legislative Speaker Wang Jin-pyng who was elected in Kaohsiung County, promised to give full support to the Kuomintang mayoral candidate in that southern county, Huang Chao-shun. However, Wang said he cannot serve as Huang's campaign manager because of his demanding job in the legislature. 'I can only help her to campaign in Kaohsiung on weekends, therefore, I'd rather to serve as the nominal director of her campaign office.' Wang said. Although the incumbent Kaohsiung Mayor Chen Chu is considered the favorite in the race, Wang said Huang has chance because the KMT won three of the four legislative seats in Kaohsiung County two years ago.
