What is the link between socioeconomic disadvantage and vote choice? The literature on this question is fragmented and points to motivations based on welfare policy, immigration policy or anti‐establishment sentiments. To test which of these motives explains differences in voting behaviour between classes, a conjoint experiment in which fictitious candidates present randomly assigned positions was designed. The experiment evaluated the relative importance of the position on welfare, immigration and anti‐establishment as well as candidates’ occupational background. By splitting the analyses into lower, middle‐ and upper class voters, it was found that lower class voters are most distinct from other voters in their preferences for anti‐establishment candidates. Strikingly, lower class voters even support welfare retrenchment, as long as it is an anti‐establishment candidate proposing it. The experiment also found a general tendency to vote against career politicians across classes and remarkably few differences regarding immigration preferences.
