Bringing background back in: A new Dutch party and the revival of socio-economic background voting

Western democracies have witnessed gradual decline of voting according to socio-economic background factors. However, the emergence of elderly parties suggests increasing mobilization along generational lines, which would partly reverse this pattern. While religion and class voting have decreased, such new generational divide might make age, education and income salient (again). However, to what extent is support for these parties driven by such mobilization—rather than by a-political protest, or by politics as usual? Focusing on 50Plus in the Netherlands, the most successful current Western elderly party, we find evidence for mobilization on a new divide. Many older, less educated voters who feel poor vote for 50Plus, irrespective of their feelings of mere protest or their position on dominant policy issues. Furthermore, perceptions of 50Plus substantially vary with age and income combined. Our findings suggest that 50Plus heralds the emergence of a novel divide. To what extent this divide revitalizes socio-economic background factors in Western politics remains to be seen
