KMT presidential primary On 20 April 2015, Hung registered for the KMT presidential primary held prior to the
2016 presidential elections. She pledged for fair and open election process under a democratic mechanism. Hung passed the 30% approval rating threshold in three KMT presidential primary polls on 14 June 2015, with an average approval rating of 46.20%. She was officially nominated as the KMT presidential candidate during the National Party Congress on 19 July 2015 at
Sun Yat-sen Memorial Hall in Taipei. During her speech, she promised peace, openness, equal distribution of wealth and morality to the people of Taiwan if she were elected. She would also push for a peaceful
cross-strait relations based on the
1992 Consensus.
Presidential campaign Hung started her campaign in
Taichung on 23 July 2015. During an interview with a local radio station, Hung stated she would take the interests of the people into account, as well as the
ROC constitution, when making decisions. She promised to sign a peace agreement that would improve military trust between Taiwan and China. She hoped that the mainland will allow Taiwan more opportunities to join international organizations and thereby boost its regional economic strength. She also pledged to improve the economy through job creation and build a just and equal society. Hung's campaign has been compared to the
New Party's
pro-Chinese unification stance. Her China policy, known as "one China, same interpretation," aims to have the People's Republic of China recognize the government of the Republic of China without recognizing the ROC as a state. President Ma Ying-jeou has supported this view, calling it no different from his own "one China, different interpretation" based on the
1992 consensus, though Kuomintang chairman Eric Chu has opposed it. Hung's run for president had been continually beset by rumors that she would withdraw from the race prior to the elections, an action Hung denied considering. On 26 July 2015, the spokesperson of Hung's campaign team Jack Yu (游梓翔) said that he would tender his resignation on 1 August 2015 to return to his teaching position at
Shih Hsin University. However, he stayed on as adviser to Hung's public and media relations team. With a KMT-sanctioned poll revealing that Hung's support was at 13% in early October 2015, Central Standing Committee member Chiang Shuo-ping proposed a party congress be called to review Hung's candidacy. Due to her poor performance in polls, 91% of delegates at the congress, held on 17 October, chose to replace Hung as KMT presidential candidate. KMT chairman Eric Chu was selected as the replacement candidate. Hundreds of Hung's supporters gathered outside
Sun Yat-sen Memorial Hall to protest the party congress being held inside the building. On 22 October, Hung announced that she would return all campaign contributions made since 23 September, a total of NT$11.83 million, to 2,633 donors. After her presidential campaign came to a close, New Party chairman
Yok Mu-ming attempted to convince Hung to switch parties and run for the legislature as a New Party candidate. Hung rejected this offer in November 2015, announcing her intention to stay with the KMT, but not to run a legislative reelection campaign in 2016. Hung later wrote a book about her presidential campaign, titled
Unfinished Presidential Road. In December, Chu invited Hung to lead the group of advisers he had assembled for his campaign. ==Kuomintang chairmanship==
