US Interest Groups, Political Parties, and Electoral Systems

Interest Group

An organization (also called a 'lobby') that tries to influence public policy without sponsoring candidates under its own name.

Faction (Madison)

Madison's term for interest groups in Federalist #10. Groups united by a common interest adverse to the rights of others — dangerous but inevitable; suppressing them would destroy liberty.

Most Durable Source of Faction

The unequal distribution of property — those with more property have stronger incentives to organize and protect their interests.

Tocqueville on IGs

Americans' tendency to join voluntary associations reflects a healthy, vibrant democracy.

Interest Group Entrepreneur

An individual who invests time and resources to organize a group around a shared interest. Example: Cesar Chavez founding the United Farm Workers Union.

3 Variables for IG Formation

1) An adverse change creates awareness/motivation. 2) Quality of leadership. 3) Higher socioeconomic status increases likelihood of joining.

Economic IGs

Business groups, trade associations, corporations. E.g., Chamber of Commerce, CA Farm Bureau, Business Roundtable.

Labor IGs

Represent workers and unions. E.g., United Auto Workers, California Faculty Association. Note: Union membership has dropped while income inequality has risen.

Professional Associations

Promote autonomy and interests of professionals. E.g., American Medical Association, National Education Association.

Public/Citizen IGs

Advocate on specific public rights or issues. E.g., NRA (2nd Amendment), Sierra Club (environment), ACLU (civil liberties).

Governmental IGs

Associations of elected or appointed officials. E.g., National Conference of Mayors, Congressional Black Caucus.

Ideological/Single-Issue IGs

Focused on a specific ideology or issue. E.g., Christian Coalition, Howard Jarvis Taxpayers Association.

Direct Lobbying

Hiring professional lobbyists to represent the IG directly before legislators. ~11,862 registered lobbyists in D.C.; ~42% of former Congresspeople become lobbyists.

Indirect (Grassroots) Lobbying

Mobilizing the public to contact their elected officials — letter-writing, phone calls, email campaigns.

Information Campaigns

Efforts to shift public opinion by bringing the IG's views to the public's attention through media and advertising.

Coalition Building

IGs with compatible interests team up for greater political influence. E.g., solar companies + environmentalists.

Legal Action

Using the courts to achieve policy goals — especially used by public interest/citizen groups.

PACs (Political Action Committees)

Raise and contribute money to candidates. National PACs can give $5,000 per candidate per election cycle. ~7,500 active PACs gave ~$435M to Congress candidates.

Political Party

An organization that sponsors candidates for political office under its own name — unlike IGs, the party label appears on the ballot.

Party Functions

1) Nominate candidates. 2) Structure the voting choice. 3) Propose alternative government programs. 4) Coordinate government officials.

One-Party System

A system where only one party controls government with no real competition. E.g., Former USSR, China.

Two-Party System

A system dominated by two parties. E.g., United States (Republicans and Democrats).

Multi-Party System

Most other democracies — enabled by proportional representation.

Single-Member Districts / Plurality Voting

Winner-take-all elections — whoever gets the most votes wins. Punishes third parties even if they win 20% nationally, because they still get 0 seats.

Proportional Representation

Europe's system — parties get seats proportional to their vote share, enabling multi-party systems.

Dualist Theory

The US has always had a fundamental duality of interests (North/South, labor/business, liberal/conservative) sustaining exactly two parties.

Social Consensus Theory

Americans broadly agree on capitalism, the Constitution, and meritocracy — reducing the need for ideologically radical parties.

Psychological/Sociological Theory

Americans are socialized into the two-party system through family and community — party loyalty is a learned identity.

Electoral College

Requires 270 electoral votes — minor parties with no regional base cannot realistically compete.

Closed Primary

Only registered party members may vote in the party's primary.

Open Primary

Any registered voter may participate in either party's primary.

Blanket/Jungle Primary

All candidates from all parties on one ballot. In Louisiana, 50%+1 wins outright without a general election.

Top-Two Primary (CA)

All candidates on one ballot — the top two vote-getters advance to the general election regardless of party.

Bolter Parties

Splinter off from a major party (e.g., Theodore Roosevelt's Progressive Party — won 27.4% in 1912; Dixiecrats split from Democrats).

Farmer-Labor Parties

Represent agricultural and working-class interests. E.g., People's Party / 'Populist Party.'

Ideological Protest Parties

Challenge prevailing political/economic doctrines. E.g., Socialist Party, Libertarian Party.

Single-Issue Parties

Organized around one specific issue. E.g., Free Soil Party (opposed slavery expansion), Prohibition Party (ban alcohol).

Role of Third Parties

Address issues ignored by major parties; they rarely win but can influence outcomes and force major parties to adopt their issues.

Responsible Party Model

Four principles: 1) Parties present distinct policy programs. 2) Voters choose based on programs. 3) Winning party implements its program. 4) Voters hold the party accountable in the next election.

Reality vs. Model

Most voters choose based on candidate personality/identity, not party program — weakening the responsible party model.
