“…However, taking stock of the literature on PRR parties, Minkenberg (2017:12) has recently criticized that this scholarship tends to lack a broader theoretical framework or a comparative approach and neglects the extra-parliamentary dimension (see alsoVeugelers and Menard, 2018: 288), such as interactions between parties and their social and political environment. Some of these questions have been addressed in recent work (Bustikova, 2014; Mareš and Havlík, 2016; Minkenberg, 2015; Minkenberg, 2017; Pirro, 2014; 2015; Pytlas, 2015; Werkmann and Gherghina, 2018). Comparing PRR parties in CEE and Western Europe, studies underline the importance of left-wing economic orientation among CEE PRR parties (Bustikova, 2018; Pirro, 2017; Varga, 2018), the role of historical legacies and of territorial revisionism (de Lange and Guerra, 2009; Minkenberg, 2017; Pytlas, 2013) or the prominence of perceived threats from autochthonous ethnic minorities (Bustikova, 2014) as important characteristics of electoral mobilization.…”
