An interest group is an organized group of people who share policy goals and try to influence government decisions through lobbying, mobilizing the public, and supporting candidates. In AP Gov, interest groups are the core evidence for the pluralist model of democracy (Topic 1.2).
An interest group is an organized group of individuals who share common objectives and actively work to shape public policy. Think of the NRA, the Sierra Club, the AARP, or the Chamber of Commerce. Each one represents a slice of society (gun owners, environmentalists, retirees, businesses) and pressures government to act on that slice's behalf. They do this by lobbying officials, mobilizing voters, building coalitions with other groups, and funding campaigns through PACs.
Here's the AP-specific part. Interest groups aren't just a Unit 5 vocabulary word. They're the living proof of pluralist democracy, one of the three models of representative democracy in Topic 1.2. Pluralism says policy gets made through competition among many nongovernmental groups, and no single group dominates because they all check each other. Madison saw this coming in Federalist No. 10. He called these groups "factions" and argued a large republic would keep any one faction from taking over. Interest groups are factions with office space and lobbyists.
Interest groups sit at the heart of Topic 1.2 (Types of Democracy) in Unit 1 and support learning objective AP Gov 1.2.A, which asks you to explain how models of representative democracy show up in real U.S. institutions and debates. When the exam asks you to identify pluralist democracy in action, the correct answer almost always involves interest groups competing to influence policy. The concept also anchors the Federalist No. 10 vs. Brutus No. 1 debate, one of the required foundational document matchups. Madison's argument that a large republic controls factions is basically an argument that interest group competition is healthy. Brutus No. 1 worried that in a huge republic, ordinary people lose their voice, which previews the modern critique that wealthy, well-organized groups drown out everyone else (that critique is elite democracy talking).

Pluralist Democracy and Federalist No. 10 (Unit 1)
Interest groups are the modern version of Madison's "factions." Federalist No. 10 argues you can't eliminate factions without destroying liberty, so the fix is a large republic where so many groups compete that none can dominate. That's pluralism in a powdered wig.
Lobbying (Unit 5)
Lobbying is the main tool in the interest group toolbox. The group is the organization; lobbying is what it does, directly contacting legislators, bureaucrats, and even courts (through amicus briefs) to push its agenda.
Political Action Committee (PAC) (Unit 5)
A PAC is the fundraising arm an interest group uses to legally donate money to campaigns. The interest group sets the policy goals; the PAC writes the checks. Don't treat them as the same thing on the exam.
Grassroots Mobilization (Unit 5)
When an interest group can't win by lobbying insiders, it goes outside, organizing ordinary people to call representatives, protest, and vote. This is where interest groups overlap with the participatory model of democracy, not just the pluralist one.
Multiple-choice questions love using interest groups as the textbook example of pluralist democracy. Common stems ask which scenario "best illustrates the pluralist model," what checks any single group from gaining too much power (answer: competition among groups), and why both Madison in Federalist No. 10 and pluralist theory would like the same constitutional structures. You should also be ready for the critique angle, since MCQs ask what pluralism fails to account for (unequal resources mean wealthy groups punch above their weight, and many citizens belong to no group at all). On SAQs, interest groups show up as a mechanism linking public opinion to policy. The 2018 SAQ on whether majority opinion shapes policy change is the classic setup, where interest group activity is a strong example of how policy can move toward (or away from) what the majority wants.
Both organize people to influence government, but the goals differ. A political party tries to win elections and run the government by getting its candidates into office. An interest group doesn't run its own candidates; it tries to influence whoever wins, on a narrower set of policy issues. Quick test: parties want to control government, interest groups want to influence policy. The NRA doesn't nominate anyone for president, but it absolutely cares how the president votes on guns.
An interest group is an organized group with shared policy goals that pressures government through lobbying, mobilization, and campaign support.
Interest groups are the key evidence for the pluralist model of democracy, which says policy emerges from competition among many nongovernmental groups (AP Gov 1.2.A).
Madison's "factions" in Federalist No. 10 are essentially interest groups, and his large-republic solution is the founding-era version of pluralist theory.
The pluralist check on power is competition itself: many groups fighting each other keeps any one group from dominating.
The main critique of pluralism is inequality, since well-funded groups have far more access and influence than poor or unorganized citizens.
Interest groups influence elections but do not nominate or run their own candidates, which is what separates them from political parties.
An interest group is an organized group of people who share policy goals and work to influence government decisions, mainly through lobbying, grassroots mobilization, and campaign donations via PACs. Examples include the NRA, AARP, and the Sierra Club.
Parties run candidates and try to control government; interest groups influence whoever is in office on a narrower set of issues. The Democratic Party nominates candidates, while the Sierra Club lobbies them on environmental policy.
No. A PAC (Political Action Committee) is the legal fundraising arm an interest group uses to donate to campaigns. The interest group is the broader organization; the PAC handles the campaign money.
He thought factions were dangerous but unavoidable, since banning them would destroy liberty. In Federalist No. 10 he argued a large republic would contain factions by forcing so many of them to compete that none could dominate, which is the logic behind pluralist democracy.
Pluralist democracy, which emphasizes group-based activism by nongovernmental interests competing to influence policy. Critics counter with the elite democracy view, arguing wealthy groups dominate while unorganized citizens get ignored.
