The rise of the opposition party in Taiwan: explaining Chen Shui-bian’s victory in the 2000 Presidential election

The 2000 Taiwan presidential election drastically changed Taiwan’s political landscape. For the first time in Taiwan, an opposition party candidate, Chen Shui-bian, won the presidential race, receiving 39.3% of the popular vote. To understand the factors that determined the election’s outcome, we analyze survey data from the 2000 presidential election. First, we study whether a divided ruling party was the cause of the opposition party candidate’s victory. That is, would the ruling party have lost if one of the trailing candidates had opted not to run? Second, there were charges following the election that the Kuomintang misled people into believing their candidate was still leading in the polls, when he was really running third, and this misinformation led people to vote differently than they would have otherwise, possibly giving the election to the opposition party candidate. We examine the validity of this claim by measuring the degree to which strategic voting could have influenced the outcome. Third, to understand the underlying dimensions of the electoral competition in Taiwan and to understand each candidate’s electoral support, we run a multivariate statistical model to study how strategic voting, candidate personalities, party identification, and issues influenced respondents’ vote choices. Finally, we discuss the effects of election polling data on election outcomes.
