The Issue Agenda, Party Competence and Popularity: An Empirical Analysis of Austria 1989-2004

This article analyses the effects of the issue agenda and of party competence on party popularity. Based on the salience and the issue ownership literatures, shifts in party support may be attributable to two factors: changing voter perceptions of issue salience and shifts in perceived party competence. We thus hypothesize that (1) a party's popularity increases if the public issue agenda changes in its favour such that its "best" issues become more important to voters and (2) that voters' changing perceptions of party competence account for shifting party popularity. Using annual macro data on voter perceptions of the issue agenda, party competence and popularity in Austria, we find no support for the first hypothesis. Rather, voter perceptions of party issue competence vary considerably and this variation accounts for the parties' level of popular support. This suggests that party competition plays out more by what politicians actually do and what impression they give about their deeds and competence than by exercising influence on the issue agenda.
