Abstract The transformation of the Belgian party system has unfolded asymmetrically: while conservative and far-right parties have thrived in Flanders, the populist right vote has not (yet) been mobilized in Francophone Belgium. Focusing on the demand side of electoral politics, this article explores whether these disparities on the supply side mirror distinct political dimensions and cleavages in both regions. By using an innovative methodology of (class-specific) multiple correspondence analysis, we find that the Flemish and the Francophone political space are largely alike – both in terms of the composition of their political dimensions as in their cleavage structure. However, we also find that Francophones adhere to a distinctive welfare consensus, which prevents working-class embourgeoisement and likely moderates the electoral fortunes of the far right. Overall, our results challenge the common stereotypes of a ‘conservative Flanders’ and a ‘progressive Wallonia’.
