This article aims at unifying the theory of spatial votin and the theory that is variously called conceptualization, information, or sophistication. Following Down's early insight on uncertainity as well as recent developments in both literatures, I argue that it is of critical importance that spatial voting models explicitily incorporate information effects. For this purpose, I develop a heterogeneity. This model is applied to the Taiwan Eleection and Democratization Study's 2004 post-presidential election survey data. In 2004, Taiwan's political landscape was dominantly defined by the Green vs Blue ideological cleavage, and the candidates wwere preceived as taking divergent positions. This article investigates the effects of information and activism on the spatial structure and their implications on candidates' strategies. My findings confirm the existance of these effects on voter uncertainty in the frmework of spatial analysis. |
