Scholars studying the electoral breakthroughs of right-wing illiberalism have arrived at two general conclusions: while they largely rejected the hypothesis that this phenomenon is grounded in voters’ attitudinal shift, they have shown that those voting for the illiberal Right have distinguishing socio-economic and attitudinal characteristics. My analysis reconciles these two sets of findings by documenting the gradual emergence and transformation of the right-wing electorate in Poland in the period 1993–2018 and points to the consolidation of a right-wing partisanship as an organizing factor of the “illiberal moment.” Using the POLPAN panel dataset I find that populist and authoritarian attitudes indeed emerge in Poland in the twenty-first century to distinguish those supporting the Right more and more centered around the PiS party. These attitudes, however, have been incorporated in the context of partisan rivalry—right-wing voters, for example, are more supportive of limiting democratic procedures but only when the Right is in power. In the first decade of the twenty-first century PiS also politicized the lack of partisan consensus on the expansion of the welfare state. PiS incorporated this demand in its stance legitimizing the expansion of the welfare state through what was available in its ideological repertoire: national solidarity, national victimhood, and the idea of a sovereign nation-state joined under the umbrella of Catholic symbolism. This post-consensus polarization and asymmetrical political radicalization resembles the “illiberal moment” in Western Europe that followed the convergence between center-left and center-right parties but they lack a crystallized class-based political identity and social-democratic understanding of political economy to build on.
