According to Taiwan media reports on March 19, the DPP’s Nantou County Mayor’s primary election was approved by the Executive Director of the Central Joint Service Center of the Administrative Organization, Cai Peihui, , but the polls were changed to coordinate the decision of candidates, which made the outside world puzzled. The Kuomintang Nantou County Mayor candidate Xu Shuhua questioned that the Democratic Progressive Party originally said that the Nantou County Mayor primary election was based on the poll results, but did not announce the change of the polls to coordinate decisions, which violated the democratic election procedures. Cai Peihui also lost her position and could not be called "the strongest candidate for the Democratic Progressive Party."
Xu Shuhua said that Cai Peihui was a candidate for the Nantou County Magistrate whom Tsai Ing-wen was "selected" two years ago. She used the resources of the whole party to create benefits for Cai Peihui. Unexpectedly, Jiji Town Mayor Chen Jiheng also strives to run for the Nantou County Magistrate, disrupting the DPP's election layout.
The Central Election Meeting of the DPP decided to hold a primary election poll, and decided that Cai Peihui or Chen Jiheng would qualify. The two also visited the grassroots level to win the support of the people of Nantou County, and emphasized that the polls would be used to select the "DPP's strongest candidate."
Originally, the DPP should have announced the poll results today to decide who wins. Unexpectedly, the DPP abandoned the polls and instead announced that Chen Jiheng retired from the election and Cai Peihui represented the election as the county magistrate. She believes that such an approach violates electoral democratic procedures. She also suspected that there was something wrong with the poll results. Maybe Cai Peihui's poll was not as expected, but under Tsai Ing-wen's will, the whole party could only announce the decision to "coordinate" to run for election on behalf of the Democratic Progressive Party.
She said that no matter who represents the DPP to run for election, she respects her opponents, but the DPP abandons the poll results and instead decides candidates in a coordinated manner. It is difficult to resolve the doubts of county citizens. Cai Peihui also lost her position. In the next county magistrate election, it is difficult to claim to be the strongest candidate for the DPP.
