title: Kuomintang
context: In 2005, then-party chairman Lien Chan announced that he was to leave his office. The two leading contenders for the position included Ma Ying-jeou and Wang Jin-pyng. On 5 April 2005, Taipei Mayor Ma Ying-jeou said he wished to lead the opposition KMT with Wang Jin-pyng. On 16 July 2005, Ma was elected as KMT Chairman in the first contested leadership in KMT's 93-year history. Some 54% of the party's 1.04 million members cast their ballots. Ma garnered 72.4% of vote share, or 375,056 votes, against Wang's 27.6%, or 143,268 votes. After failing to convince Wang to stay on as a vice chairman, Ma named holdovers Wu Po-hsiung, Chiang Pin-kung and Lin Cheng-chi (林澄枝), as well as long-time party administrator and strategist John Kuan as vice-chairmen. All appointments were approved by a hand count of party delegates.
