Electorate
The CDA is mainly supported by religious voters, both Catholics and Protestants. These tend to live in rural areas and tend to be elderly. In some periods, however, the CDA has functioned as a centrist party, attracting people from all classes and religions.
Geographically, the CDA is particularly strong in the provinces of North Brabant, Limburg and Overijssel and in the Veluwe and the Westland areas. In the 2006 elections the CDA received the highest percentage of votes in the municipality of Tubbergen, Overijssel (66,59% of the vote). The CDA is weaker in the four major cities (Amsterdam, Rotterdam, The Hague and Utrecht) and in Groningen and Drenthe.
