This thesis explores reasons why a voter would vote for a ¡§independent¡¨candidate in a city council¡¦s election. Since respondents in a telephone survey are not able to give their thoughts and description of vote intention thoroughly. given few survey questions .I therefore chose in-depth interview conducted before the election day to explore the real thoughts of the voters. My in-depth interview respondents are selected by telephones surveys and were interviewed regarding four topics, including party identification, political views, candidates and social networks. I find that partisanship is not the main factor of voting for an independent candidate. Instead, the key is his or her ability to serve the voters. The second factor is the ability to execute the public welfare policies and the third is education background and experiences in the field of public service. Fourth social network has limited effects on voters who were born in the 70¡¦s and 80¡¦s. Moreover, I discovered that the effects of the party ideology on voting behavior might differ across levels of elections. In particular, Kaohsiung voters will take the cue of party ideology at the city mayor¡¦s election, while this may not apply to a city council¡¦s election.
