The conditional party mandate: A model for the study of mass and elite opinion patterns

Abstract.  This article explores the pattern of opinions within political parties. What is the level of issue congruence between voters and elected leaders? The article introduces two ideas for the analysis of mass and elite opinion patterns. First, the authors challenge the unidimensional conception of mass-elite linkages, and argue that the opinion structure of political parties may best be understood in the context of a multidimensional policy space. Second, they contest the proximity logic of the traditional party mandate model. In so doing, they propose the 'conditional party mandate model', arguing that 'direction' rather than 'proximity' attracts voters' interest and attention. The authors contend that in issues of principle significance for a particular party (so-called 'core issues'), the party's voters and representatives will proceed in the same direction, but the representatives will stress their position more strongly than the voters. In issues that are less significant to the parties, the relationship between the two levels will be fortuitous and less clear. The analyses, which are based on elite and mass survey data from the Norwegian political system, support the authors' hypotheses concerning positional issues. When the direction of an issue is given, representatives are more extreme than voters.
