Party loyalty and voter mobility in the four National Assembly elections in the 1980s and 1992 are investigated. The consequences of the low level of party loyalty to the major parties, the fragile party system and frequent amendment of the electoral systems are examined. Components of Korean political culture are understood as the basic framework in the analysis. The consequences of low party loyalty and nonvoters' electoral behavior are also examined. The major find;'lgs in this study are the low level of party loyalty and the existence of a volatile electorate in the 1980s. Party loyalty for the DJP was low in 1985 (54.7 percent) and dropped even further in 1988 (41.7 percent). The DJP did not have a large group of loyal supporters in the 1980s although it was able to consistently obtain about one third of the valid votes cast in these elections. The electorate is not to be blamed for their volatile electoral behavior. Their low party loyalty and volatility resulted from the insufficient and inadequate function and performance of the party leaders and their parties. Changes in the electoral system and party structure have led to the emergence of strong regionalism, insufficient performances of parties, and the low level of voter loyalty. This low party loyalty, in turn, became one of the major causal factors for the mergers of political parties in 1990 and 1991. These mergers of viii parties differ from those of the 1950s and 60s in terms of their motives and patterns. The uncertainty management approach replaced the traditional and power approaches in explaining the merger phenomenon. In other words, the political leaders felt the necessity of uncertainty management after the 1988 National Assembly elections because of unsatisfactory election results. Merger politics are the current form of Korean politics. Besides the level of low party loyalty and fragile electoral behavior, one of the major findings is that components of political culture regulated the electoral dynamics in Korea in the 19805 and the early 1990s. It is concluded that the political culture regulation theory was examined and supported in this study. The voter mobility tables for the 1988 and 1992 National Assembly elections show that the merger of three parties in 1990 strengthened the 1988 ruling party voters' loyalty to the ruling DLP in 1992. It has increased from 41.7 percent in 1988 to 55.9 percent in 1992. ix TABLE OF CONTENTS ACKNOWLEDGMENTS v ABSTRACT vii LIST OF TABLES xii LIST OF FIGURES xiv LIST OF MAPS xv LIST OF ABBREViATIONS xvi CHAPTER 1.
