Electorate
The electorate of the CHU has seen three decisive shifts, especially in its relation with the ARP, the other Protestant party. Although dates are given here, the changes were gradual
- Between 1908 and 1917 the CHU appealed to the aristocracy, the people with double names, nobility, land owners, high officers and high-ranking civil servants, who opposed universal suffrage.
- Between 1917 and 1967 the CHU appealed to members of the Dutch Reformed Church.
- Between 1967 and 1977, in the time of secularization and depillarization the party retained its conservative image.
