An Interest-Groups<\/a> is a formal organization of individuals or entities that attempt to influence Public-Policy<\/a> to benefit specific causes or industries. Unlike Political-Parties<\/a>, which focus on electing candidates to office, interest groups focus on influencing those already in power. As noted by Britannica<\/a>, these groups are fundamental to the process of Representative-Democracy<\/a>.<\/p> Groups are often categorized by their goals. Economic-Interest-Groups<\/a> include Labor-Unions<\/a> and trade associations like the U.S.-Chamber-of-Commerce<\/a>. Public-Interest-Groups<\/a> advocate for the collective good, such as the Sierra-Club<\/a> for the environment or Common-Cause<\/a> for government reform. Professional groups, such as the American-Bar-Association<\/a>, represent specific vocations.<\/p> The primary method of influence is Lobbying<\/a>, which involves providing information to legislators. Groups also engage in Electioneering<\/a> by providing financial support through Political-Action-Committees<\/a> (PACs). The Supreme-Court<\/a> case Citizens-United-v-FEC<\/a> significantly expanded the ability of these groups to spend money on political communications, a shift detailed by The Federal Election Commission<\/a>. Furthermore, groups use Litigation<\/a> to challenge laws in court, often filing Amicus-Curiae<\/a> briefs.<\/p> Political science offers three main theories regarding interest group influence: Pluralism<\/a>, which views group competition as beneficial; Elitism<\/a>, which suggests wealthy interests dominate; and Hyperpluralism<\/a>, which argues that an excess of groups leads to gridlock. The concept of the Iron-Triangle<\/a> explains the stable relationship between interest groups, Congressional-Committees<\/a>, and the Bureaucracy<\/a>.<\/p>Types of Interest Groups<\/h2>
