According to the latest CNA wire, for the DPP, districts are looking hot or cold. Legislators are likely to all shoot for districts they consider as safe as possible when registration opens next week. According to the DPP Taipei Branch Chair Lee Cheng-yi (李政毅), nobody wants to sign up to run in Districts 6, 7 or 8.
He said the party would probably send assassins to such districts to take care of them. I say they should send those legislators who had been critical of the DPP.
He also left room for cooperation with the TSU and said the primary process would be finished by June. :( That's a long time away.
DPP chairman Yu Shyi-kun has mentioned he's working hard to settle these questions and tries to make negotiations for 3 of those 22 difficult districts a day (立委協調的部分，他也在做，一天還協調三個選區，他都盡力而為).
There's eight legislative districts in Taipei city, so if DPP people are unwilling to run in three of them is very frowny face.
In any case, here's the list of who has expressed interest in running in Taipei:
District 1 (Beitou/ N. Shilin [Tianmu]) -- Former city councilor Chen Cheng-teh (陳正德)、Lin Cho-shui (林濁水), Luo Wen-chia (羅文嘉), Kao Chien-chih (高建智)
District 2 (Datong/ S. Shilin) -- Wang Shih-Cheng (王世堅), Hsiao Bi-khim (蕭美琴), and possibly Lan Mei-chin (藍美津)
Distrist 3 (Zhongshan/N. Songshan) -- Kuo Cheng-liang (郭正亮)
District 4 (Neihu/Nangang) -- Hsu Kuo-yung (徐國勇)
District 5 (Wanhua/ N. Zhongzheng) -- Tuan Yi-kang (段宜康)
District 6 (Da'an) -- nobody ...
District 7 (Xinyi/S. Songshan) -- nobody ...
District 8 (Wenshan/ S. Zhongzheng) -- nobody ...
