Class voting for radical-left parties in Western Europe: The libertarian versus authoritarian class trade-off

Which classes vote for radical-left parties (RLPs) in Western Europe? Previous research indicates that RLPs are strong among production workers and socio-cultural professionals, though not necessarily among both at the same time. Starting from the observation that these two classes take opposite stances on cultural issues, we trace variation in class voting back to RLPs’ positions on the cultural dimension. Combining voter-level data from the European Social Survey (2002–2018) with information on the positions of 23 RLPs from the Chapel Hill Expert Survey, we report robust evidence of a libertarian versus authoritarian class trade-off: RLPs with less libertarian positions receive relatively less support from socio-cultural professionals and relatively more support from production workers. These findings add to evidence that class voting varies with party positions. Ours is the first study to demonstrate this for RLPs, showing how, in the early 21st century, cultural positions matter for class voting.
