CEVAP:

Interest group dynamics are complex. Dependency on large membership for support makes them vulnerable to limited interests of citizens to participate. Because of the large membership of the group, support for financial matters are required. Also, receiving the attention of elected officials who are responsible for policies addressed are required. Some groups draw support from greater numbers of citizens than directly involved in the issues supported. Levels of participation may be exaggerated. Subsequently, some issues may be relevant to minority interests but can win the support of the majority of citizens.
