Alternative models of issue voting: The case of the 1991 and 1995 elections in Belgium

Abstract. Previous research has indicated that the success of the directional model of issue voting depends on levels of political sophistication and how party position is measured. Using 1991 and 1995 Belgian Election Surveys, the predictive power of proximity and directional measures are compared controlling for both variables. It is shown that when one uses overall mean placements, instead of mean placements by level of political sophistication, the proximity effect declines most among the highly sophisticated voters. The article also compares the performance of the proximity and directional measures across party systems. Contrary to theoretical expectations, party–system differences between Flanders and Wallonia do not affect the explanatory power of either of these measures. It is only in the cases of the liberal, socialist and extreme right parties that the directional measure is clearly superior. A closer analysis of this result indicates that the relative success of the directional measure is due to the limited number of issues from which those parties draw support.
