Who leads, who follows? Re-examining the party-electorate linkages on European integration

Abstract: This article re-examines and evaluates the link between electorates' opinions and national political parties' positions on European integration, i.e. the extent to which political parties lead and/or follow public opinion on this issue. Applying a method for causal modelling (Granger causality tests) to panel data concerning political parties' positions and voters' opinions in 15 countries from 1973 to 2003, I find (contrary to previous investigations of this relationship) that there is little empirical support for an electoral connection or reciprocal causation between party positions and electorates' opinion regarding European integration. Parties have an influence on voter opinions, but are at the same time unresponsive to changes in voter opinion.
