POL-371: Political Parties and Interest Groups

A study guide to SNHU's POL-371, the upper-level political science course on the groups that connect citizens to government.

Updated October 2026 · 5 min read

POL-371 at Southern New Hampshire University looks at political parties, interest groups, voting blocs, activist groups and special-interest mobilization. SNHU's catalog describes the course as an applied study of how these groups act as mediators between citizens and government.

A central question runs through the course: how effective are different groups at representing citizen interests and influencing voting behavior? Students find it demanding because it asks for evidence, not opinion. You must show how a group's strategy connects to a measurable pattern in voting or participation.

What POL-371 Covers

The catalog description names the groups and the purpose of studying them. Here is how those phrases translate into study topics.

Catalog phraseWhat to expect
Political partiesHow parties organize, nominate candidates, build coalitions and shape the choices voters see
Interest groupsHow organized groups lobby, mobilize members and try to influence policy
Voting blocs and activist groupsHow identifiable groups of voters and activists act collectively
Special-interest mobilizationHow narrow issues turn into organized political action
Voting trends and participationUsing evidence on turnout and vote choice to judge a group's influence
Civic engagementWhether group activity improves, or distorts, citizen participation

The phrase "applied approach" matters. Expect to analyze real organizations and real electoral patterns, not only to define terms.

Key Concepts Explained

Mediating Institutions

Parties and interest groups sit between voters and officials. They gather preferences, package them into platforms or demands, and carry them into government. A good answer asks what a group gains from that role and what it leaves out, such as people who are hard to organize.

The Collective Action Problem

Large groups with shared interests often struggle to organize because each member can benefit without contributing. Groups respond with member benefits, leadership, or a very focused goal. This idea helps explain why small, well-funded interests can look stronger than large, diffuse ones.

Illustrative example (invented): Imagine a trade association with 200 members, each gaining a large benefit from one rule change, and a consumer group of millions, each gaining a tiny amount. The association can coordinate and fund lobbying easily. The consumer group faces a free-rider problem. An analyst would link this difference to likely influence and then test it against actual policy outcomes.

From Influence Claims to Evidence

It is easy to say a group is influential. It is harder to show it. Stronger papers pick an indicator, such as turnout in a bloc, endorsement patterns or a vote on a bill, and explain why it is a fair measure and what it cannot prove.

Typical Assignments and How to Approach Them

Assignment details change by term, so rely on your own prompt and rubric. Courses of this type typically use the following formats.

Assignment typeWhat it testsHow to approach it
Group case analysisApplying theory to a named party or interest groupState your claim, then support it with a strategy and an outcome
Voting trend analysisReading participation or vote-choice evidenceName the data source, the pattern and a cautious interpretation
Civic engagement proposalLinking analysis to improvementOffer a realistic recommendation and its likely limits
Discussion postsConcise argument and peer responseMake one clear point with one source, then engage a classmate's point

Parties and Interest Groups Compared

Many weaker papers blur the two kinds of organization. A short comparison table keeps the distinction clear and gives you a ready framework for any case.

FeaturePolitical partyInterest group
Main goalWin elections and control governmentInfluence policy, whoever governs
Typical toolsCandidates, platforms, campaigns, coalitionsLobbying, endorsements, donations, member mobilization
AccountabilityVoters at the ballot boxMembers, donors and supporters
Common weaknessMust appeal to broad coalitionsMay represent narrow or unequal interests

Use the table as a starting point, then add exceptions. Some groups endorse candidates and look party-like, and some parties act mainly as vehicles for single issues. Pointing out such overlap shows careful thinking.

When you plan a paper, decide which row matters most to your argument. A paper on influence will lean on tools and accountability. A paper on civic engagement will lean on weakness and what each group does to include or exclude citizens.
