Due to the social turbulence that resulted from the fierce partisan competition, the Taiwanese people usually tend to refrain from voicing their political opinions in public or in unfamiliar settings. Through the secondary analysis of the survey data on the 2006 Taipei mayoral election, the current study intended to explore how the voters in Taipei think of the issue of the Red Shirt Movement and their willingness to speak out on political affairs. The result showed there is little difference in proportion between those who agree and those who disagree with the Red Shirt Movement. Yet most of the respondents were unwilling to talk about politics in public settings. Furthermore, it was found that the extent to which people were involved in the Red Shirt Movement, the perception of then-President Shui-Bian Chen's integrity, and the amount of attention to the election news in newspaper were positively associated with respondents' willingness to speak out on political issues. Besides, respondents' ethnic background was found negatively related to their willingness to express political opinions. However, there is no significant association between respondents' attitudes toward the issue of the Red Shirt Movement and their willingness to talk about political affairs in public settings. It is apparent that, through these results, the current study has to face the deficiency both in data and in theoretical applicability.
