It is commonplace to see political parties as fundamentally constrained by public opinion. By contrast, this paper argues that party competition amplifies mass ideological polarization over public policy. Specifically, the investigation concerns the relationship between mass-level ideology and ethnic exclusionism (the call for harsh immigration policies). As party competition intensifies, this relationship strengthens. The party competition thesis is tested by performing a comparative study of Denmark and Sweden. Unlike their Danish counterparts, Swedish political parties have, most of the time, refused to take opposed stands on immigration policy. In effect, the empirical data show that the individual-level association between self-reported ideology and ethnic exclusionism is considerably stronger in Denmark than in Sweden. To investigate the party competition effect in depth, both longitudinal analyses and a cross-sectional analysis are performed. Data cover the period 1990-2008.

The empirical range of populist ideologies is identified through a frame analysis of party materials and connected to the varying political and cultural opportunities of different kinds of parties. However, it is argued that at the same time a common reliance on some common populist tenets constituted an innovative strategy of the Italian right, and that as an ideology one of...
