This paper provides a framework to evaluate the primary system utilized by the two main political parties of Taiwan in the mayoral elections of Taipei and Kaohsiung cities. The finding of this evaluation is that there is a significant conflict of values between party democracy and chances of victory. This conflict should be managed in order to consolidate the effectiveness, efficiency, adequacy, equity, responsiveness, and appropriateness of the party nomination system. In addition, this paper also addresses eight signals or indicators in order to transform the existing primary system into a more integrated system with higher equality in order to prevent conflict among party members or cliques.
