Lobbies are groups that seek to influence politicians and public policy through various means including their members' votes, organizing skills, and campaign contributions. They are distinct from political parties, which aim to win elections and govern, and from social movements, which are broader collective efforts to promote or resist change in society. Voluntary organizations can encompass a wide range of groups, not all of which are focused on political influence.
