Party opportunism among local politicians after Taiwan's power transition

This paper probes into a hypothesised opportunism towards political party affiliation among local politicians in Taiwan since the power transition from Kuomintang (KMT) to Democratic Progressive Party (DPP) rule began in 2000. Longitudinal changes in election candidates' party affiliation are analysed to see what happened to the KMT's supposedly strong base of local politicians after the change of governing party. The research finds a generally high propensity of election candidates' changing or dropping their party affiliation between elections, and an increased propensity among KMT candidates after 2000. However, defections to other parties are more common in higher elections. In grassroots elections, many candidates flow in and out of their party affiliation depending on the political circumstances, but they rarely change party. Several years after the DPP gained power in presidential elections, the new ruling party is still struggling to build a strong local party organisation.
