Linkage Institutions

Channels that connect citizens to government and policymakers: political parties, elections, interest groups, and the media.

Fifteenth Amendment (1870)

Prohibited denying the right to vote based on race, color, or previous condition of servitude.

Seventeenth Amendment (1913)

Provided for the direct election of U.S. senators by voters rather than by state legislatures.

Nineteenth Amendment (1920)

Twenty-Sixth Amendment (1971)

Lowered the national voting age to 18 for all citizens.

Voter Turnout

The percentage of eligible citizens who actually vote; influenced by education, age, income, registration laws, and efficacy.

Rational-Choice and Retrospective Voting

Rational-choice voting is based on perceived self-interest; retrospective voting judges incumbents on past performance.

Prospective and Party-Line Voting

Prospective voting is based on what a candidate promises to do; party-line voting means supporting a single party's candidates.

Political Party Functions

Parties recruit candidates, mobilize voters, organize government, and provide a label that structures voter choice.

Two-Party System

A system dominated by two major parties, reinforced by single-member districts and winner-take-all (plurality) elections.

Third Parties

Minor parties that rarely win but can raise issues, influence major-party platforms, and act as spoilers.

Critical (Realigning) Election

An election that produces a major, lasting shift in the party coalitions and balance of power.

Electoral College

The body of electors that formally elects the president; each state's total equals its representatives plus senators, and most use winner-take-all.

Incumbency Advantage

The electoral edge held by current officeholders due to name recognition, funding, and constituent services.

Interest Groups

Organizations that seek to influence public policy on behalf of shared goals through lobbying, litigation, and mobilization.

Political Action Committee (PAC)

An organization that raises and spends limited, regulated money to elect or defeat candidates.

Super PAC

A group that can raise and spend unlimited money on independent expenditures but cannot coordinate directly with candidates.

Citizens United v. FEC (2010)

Ruled that limiting independent political spending by corporations and unions violates free speech, enabling super PACs.

Federal Election Campaign Act & Soft/Hard Money

Campaign finance law regulating contributions; hard money is regulated donations to candidates, soft money is less-regulated party spending.

Media as a Linkage Institution

The press informs the public, sets the agenda, frames issues, and serves as a watchdog over government.

Iron Law / Free Rider Problem

The free-rider problem occurs when people enjoy a group's benefits without joining, weakening interest-group participation.

Voter Registration Requirements

State rules on deadlines and ID; the National Voter Registration Act (Motor Voter, 1993) eased registration at DMVs.

Same-Day and Automatic Registration

State reforms that raise turnout by removing the registration hurdle; adopted unevenly, illustrating federalism in election law.

Voter ID Laws

State requirements to show identification; supporters cite fraud prevention, critics cite disparate impact on poor and minority voters.

Structural Barriers to Turnout

Tuesday voting, registration deadlines, and felony disenfranchisement lower U.S. turnout relative to peer democracies.

Political Efficacy and Turnout

Voters who believe their vote matters (efficacy) and who are contacted by campaigns are far more likely to turn out.

Demographics of Turnout

Older, wealthier, more educated, and married citizens vote at higher rates; youth turnout is lowest but rose in 2018-2020.

Midterm Drop-Off

Turnout falls sharply in midterms; the president's party typically loses House seats.

Party Platform

Statement of positions adopted at the national convention; signals coalition priorities though candidates are not bound.

Candidate-Centered Campaigns

Shift from party-run to candidate-run campaigns driven by primaries, television, and independent fundraising.

Party Realignment vs. Dealignment

Realignment shifts coalitions durably (1932); dealignment is voters drifting from both parties toward independence.

Winner-Take-All and Duverger's Law

Single-member plurality districts encourage two parties because third-party votes yield no seats.

Proportional Representation

Seats allocated by vote share, common abroad; would enable multiparty systems but is not used for Congress.

Third-Party Influence

Third parties shape agendas by forcing major parties to absorb their issues (e.g., Populists, Perot's deficit focus).

Open vs. Closed Primaries

Closed primaries limit voting to registered party members; open primaries allow any voter and invite crossover voting.

Caucus

Party meeting where participants publicly select delegates; lower turnout and more activist-dominated than primaries.

Frontloading

States moving primaries earlier for influence, compressing the nomination calendar and favoring well-funded candidates.

Superdelegates

Democratic party officials with automatic convention votes; their role was reduced after 2016.

Swing (Battleground) States

Competitive states that receive disproportionate campaign attention because of winner-take-all electoral votes.

Faithless Elector

Elector who votes contrary to the state's popular vote; states may bind electors (Chiafalo v. Washington, 2020).

Bipartisan Campaign Reform Act (2002)

McCain-Feingold banned soft money to national parties and restricted electioneering ads; partly weakened by Citizens United.

Independent Expenditure

Spending on political speech not coordinated with a candidate; unlimited after Citizens United, disclosed variably.

501(c)(4) 'Dark Money'

Social-welfare nonprofits that spend on politics without disclosing donors, unlike PACs and Super PACs.

Amicus Curiae Brief

Friend-of-the-court filing by interest groups to influence judicial decisions, an example of litigation as a strategy.

Grassroots vs. Inside Lobbying

Grassroots mobilizes citizens to pressure officials; inside lobbying uses direct contact, testimony, and drafting bills.
