describe the role of political parties in influencing public policy.

Interest groups are also known as advocacy groups or lobby groups. Interest groups play a very important role in developing political and social systems. Some groups use direct action and civil disobedience to get officials on their side regarding their policies. Wealthier interest groups have been known to use financial gain in order to convince politicians to be on their side. In recent years, interest groups have used social media to get widespread support for their causes.
