Some policies matter more: party salience and interest group access to political parties in Western democracies

Political parties and interest groups play important roles in incorporating societal interests into democratic decision-making. Recent studies have analysed the causes of interactions between individual political parties and interest groups and of interest groups' choices to seek access to one or more parties. Meanwhile, we know less about why some parties grant access to a range of interest groups while others focus on a few. This article theorises about party strategies and suggests that party salience – that is parties' emphasis on different policy areas – affects the range of interest groups to which they grant access. I combine interest group survey data from six European democracies with data from party manifestos and use regression analyses to test this hypothesis. I find that parties provide access to multiple interest groups representing various interests in legislative politics and, above all, in policy areas that are salient to them. Thus, parties are more likely to be aware of diverse interests' perspectives on policies in areas they prioritise. The results have important implications for our understanding of the consequences of party–interest group interactions in democracies.
