The power in dispute
Political parties, interest groups, and social movements

The author suggests that political parties, in current times, have lost their capacity to fulfill some of their traditional functions: articulating and aggregating interests. This phenomenon is associated with a more autonomous civil society, which has begun to act within the political system through various collective identities —interest groups and social movements— to claim new and diverse rights and, above all, greater social justice, gradually assuming some functions that were previously exclusive to political parties.
