Avoidance, ambiguity, alternation: position blurring strategies in multidimensional party competition

In a multidimensional environment, parties may have compelling incentives to obscure their preferences on select issues. This study contributes to a growing literature on position blurring by demonstrating how party leaders purposively create uncertainty about where their party stands on the issue of European integration. By doing so, it theoretically and empirically disentangles the cause of position blurring—parties’ strategic behavior—from its intended political outcome. The analysis of survey and manifesto data across 14 Western European countries (1999–2019) confirms that three distinct strategies—avoidance, ambiguity, and alternation—all increase expert uncertainty about a party's position. This finding is then unpacked by examining for whom avoidance is particularly effective. This study has important implications for our understanding of party strategy, democratic representation, and political accountability
