The Flemish-nationalist party Volksunie ceased to exist in 2001. Due to deep divisions within the party, it was decided to organise a referendum in which each party-member could vote for a project, outlining the future of the party. Since none of the three projects managed to obtain a 50 %-majority, a requisite to preserve the party name, the name Volksunie disappeared and the party was split up in two new parties. In this article we tried to answer the question which members voted for which project. A mail survey was held among a sample of Volksunie-members. Explanations for voting behaviour were found in characteristics of voters, their viewpoints on issues and their appreciation of notable party leaders. Finally, we analysed the second preference-party of the Volksunie-members in order to estimate with which existing parties the two new parties could possibly form future alliances.
