On the other hand, the individual parties try to get as many members as possible. Therefore, the Danish parties are often referred to as mass parties. As a main rule, the parties do not make special demands on the persons who wish to become members. But the candidate in question shall, of course, obey the rules of the party, agree to and be loyal to the party programme. And then, of course he or she cannot be a member of different parties at the same time.
All members join a local branch or caucus.
The caucuses contribute to propagating the points of view of the party among the general public i.a. by getting followers. At the same time, the caucuses back party representatives in municipalities as well as in the Folketing. The big parties have local branches in all municipalities, the small parties have branches in the various counties and sometimes only in certain parts of the country. All the local branches together make out the national organization of the party. If the party is represented in the Folketing, these members make out an independent group, the parliamentary group, the members of which currently hold meetings on the work going on in the Folketing.
