Abstract
The case of Nosamo has already shown that voluntarily organized online voter groups can bypass party organization and can greatly affect party politics and electoral outcomes. Inspired by the success of Nosamo, political fan clubs that compete with each other have appeared and are triggering changes in the political process. The increased political use of ICTs has aroused controversies on whether they would strengthen or weaken representative democracy. This paper tries to analyze political fanclub's influence of the party politics in the perspective of party decline theory. This paper is organized as the following: first, organizational characteristics and functions of political fan clubs are analyzed; second, the impacts of political fan clubs on changes in the parties are presented.
