Does ethno-territorial identity matter in populist party support? Evidence on the demand-side from 19 populist radical right and populist radical left national and regionalist parties

Abstract

ABSTRACT This article investigates to what extent citizens’ conceptions of nation-state identity and European identity contribute to the support for populist radical parties along the left-right and the national level and sub-state divide. Drawing on data European Social Survey data, it employs multinomial and logistical regression models to examine the connection between territorial identity and support for majority nationalist Populist Radical Right Parties (PRRP) (9 cases), national-level Populist Radical Left Parties (PRLP) (4 cases), sub-national PRRP (3 cases), and sub-national PRLP (3 cases). The overall findings confirm that nation-state identity and European identity have independent and significant effects. In several of the cases, a strong nation-state identity is positively related to support for (a) majority nationalist PRRP. A (negative) European identity is a central characteristic throughout the sample of majority nationalist PRRP and present in every single case. Sub-state PRRP supporters reject nation-state identity and, interestingly, in one case also European identity more than do other partisans. Identity effects, especially a negative nation-state identity, were present among PRLP supporters too. However, the evidence points to significantly less coherence.
