More than 20 legislators of the opposition Democratic Progressive Party (DPP) on Wednesday announced their support for DPP Chairperson Tsai Ing-wen's re-election bid. The legislators -- including Lai Ching-te, Su Chen-ching, Pan Meng-an and DPP Policy Committee Executive Director Ker Chien-ming -- voiced their support at a news conference after former Taipei County Magistrate Yu Ching registered April 9 to run in the election for DPP chief slated for May 23. Entertainer-turned-DPP Legislator Yu Tien told the press conference that at present, Tsai should focus on readying herself for her April 25 debate with President Ma Ying-jeou on a proposed trade pact with China, rather than spend time on a re-election bid. Yu said that Tsai can rest assured because all members of the DPP legislative caucus will campaign for her to solicit support from grassroots party members. Ker said that the legislators' move is aimed at allowing Tsai to concentrate on the debate. The DPP currently holds 30 legislative seats.
