ABSTRACT
For the purpose of determining the relative influence of the three potentially most important social and demographic factors on party choice-social class, religion, and language-a comparison of Belgium, Canada, South Africa, and Switzerland provides a “crucial experiment,” because these three variables are simultaneously present in all four countries. Building on the major earlier research achievements in comparative electoral behavior, this four-country multivariate analysis compares the indices of voting and the party choice “trees” on the basis of national sample surveys conducted in the 1970s. From this crucial contest among the three determinants of party choice, religion emerges as the victor, language as a strong runner-up, and class as a distant third. The surprising strength of the religious factor can be explained in terms of the ufreezing” of past conflict dimensions in the party system and the presence of alternative, regional-federal, structures for the expression of linguistic interests.
