The Class Basis of Switzerland's Cleavage between the New Left and the Populist Right

This article argues that a full grown cleavage has surfaced in Swiss politics, separating a libertarian‐universalistic (the New Left) from a traditionalist‐communitarian camp (the Populist Right). Based on survey data of Switzerland's parliamentary election 2007, it examines the cleavage's micro‐foundations and shows that the class constituencies of the New Left (the Social‐Democratic and Green Parties) and the Populist Right (the Swiss People's Party) present the almost exact mirror image of each other. The former draws disproportionate support from the salaried middle class, notably socio‐cultural professionals, whereas the latter is rallied by small business owners, production and service workers. Although anchored in the employment structure, this divide is not primarily about the economy and resources, but about culture and identity. It thus strongly correlates with opposing cultural attitudes. While small business owners and workers prefer cultural demarcation and defend national traditions, salaried professionals strongly favour international integration and multi‐culturalism.
