THESE FOUR "LINKAGE INSTITUTIONS" CONNECT CITIZENS TO GOVERNMENT — ALONG WITH:
Voter Turnout
Campaign Finance
Third Parties
Modern Campaigns
Electoral College
Linkage institutions translate what citizens want into what government does — and shape how citizens see government.

SLIDE 2 · EXPANDING THE FRANCHISE
Voting Rights Timeline
1870
15th Amendment
Bars denying the vote
based on race
Barrier: poll taxes,
literacy tests, grandfather
clauses persisted
1920
19th Amendment
Women win the
right to vote
Barrier: women of
color still blocked by
race-based barriers
1961
23rd Amendment
Grants Washington
D.C. 3 electoral votes
Barrier: D.C. still has
no voting member
of Congress
1964
24th Amendment
Bans poll taxes in
federal elections
Barrier: some states
kept poll taxes for
state/local elections
1965
Voting Rights Act
Bans literacy tests;
federal preclearance
Barrier: preclearance
formula gutted by
Shelby Co. v. Holder ('13)
1971
26th Amendment
Lowers voting
age to 18
Barrier: registration
deadlines still limit
youth turnout
Six milestones widened who could vote — but each left structural barriers for the next reform to address.
"Old enough to fight, old enough to vote" drove the 26th Amendment during the Vietnam War draft.

SLIDE 3 · WHY PEOPLE VOTE THE WAY THEY DO
Four Models of Voting Behavior
Rational-Choice Voting
Voters weigh costs & benefits and pick
whichever candidate/policy most
benefits their own self-interest.
Ex: a small-business owner votes for the
candidate proposing small-business tax cuts
Retrospective Voting
Voters judge the incumbent (or their
party) on how well things went during
their time in office — a report card.
Ex: voting out an incumbent because
the economy struggled during their term
Prospective Voting
Voters choose based on a candidate's
future promises and proposed policies —
what they say they'll do next term.
Ex: choosing a candidate for their
stated healthcare plan for next term
Party-Line Voting
Voters choose based on party
identification rather than evaluating
each candidate or issue individually.
Ex: a lifelong Democrat votes a straight
Democratic ticket down the whole ballot
Most real voters blend all four models — the AP exam asks you to identify which one a scenario illustrates.

SLIDE 4 · TURNOUT PATTERNS
Voter Turnout — Who Votes, and Why
TURNOUT RISES WITH AGE, EDUCATION & INCOME
Age
65+ ~72%
18–24 ~48%
Education
College grad ~74%
No college ~51%
Income
Top quintile ~76%
Bottom quintile ~46%
AP Tip
Know the direction of each relationship —
exact percentages matter less than trends.
Why Turnout Is Depressed
• Low political efficacy — feeling your
vote/voice doesn't matter
• Advance registration deadlines
and paperwork requirements
• Strict voter ID laws
• Limited polling locations/hours,
long lines in some precincts
• Tuesday, workday Election Day
• Felon disenfranchisement laws
(vary widely by state)
• No same-day registration in
many states

SLIDE 5 · WHAT PARTIES DO
The Five Core Functions of Political Parties
1
Mobilize &
Educate Voters
Register voters,
explain the ballot,
and drive turnout
on election day.
2
Develop Party
Platforms
Write policy
positions that give
voters a clear
choice of vision.
3
Recruit
Candidates
Find, train, and
support people to
run for office up
and down the ballot.
4
Run & Manage
Campaigns
Handle messaging,
fundraising, and
get-out-the-vote
operations.
5
Organize the
Legislature
Sort members into
caucuses, assign
committees, and
pick leadership.
Parties are one of the two major linkage institutions that connect citizen preferences to government action.
The Review Hub · AP Government Unit 5
SLIDE 6 · PARTIES IN FLUX
Why Parties Change and Adapt
Candidate-Centered Campaigns
Candidates now build their own staff,
donor lists, and media strategy — often
independent of the party organization
that once ran party-centered campaigns.
Weakens party control over nominees
Critical / Realigning Elections
Sharp, lasting shifts in which groups
support each party — new coalitions
form around a major crisis or issue and
the new alignment persists for decades.
Ex: 1932 — New Deal realignment
Shifting Coalitions
As the electorate's demographics —
race, education, geography, religion —
change, parties adjust platforms to hold
onto old supporters and win new ones.
Ex: college-educated suburban voters
Technology & Data
Social media, texting, and voter-file
databases let parties and candidates
target messages directly to voters —
bypassing traditional party machinery.
Reshapes how campaigns are strategized
Parties are not fixed institutions — they constantly adapt to survive new political and technological realities.
The Review Hub · AP Government Unit 5
SLIDE 7 · THE TWO-PARTY SYSTEM
Why Third Parties Rarely Win
VS
Winner-Take-All (U.S.)
Single winner takes the whole district
Coming in 2nd or 3rd earns zero seats
Voters fear a 3rd-party vote is "wasted"
Proportional Representation
Seats awarded to match vote share
A party with 15% of votes wins seats
Common in many multi-party democracies
Major-Party Co-optation
When a third-party idea gains real
popularity, a major party adopts it —
absorbing the third party's appeal
before it can build lasting momentum.
Ballot-Access Laws
State laws often require costly petition
signatures, filing fees, and deadlines for
a third party just to appear on the
ballot — set up by the two major parties.
Structural rules, not lack of popular ideas, are the main reason U.S. third parties almost never win office.

SLIDE 8 · HOW INTEREST GROUPS OPERATE
Interest Groups & the Iron Triangle
Lobbying Congress
Meeting with members/staff to
shape bills and provide expertise
on complex policy issues
Amicus Curiae Briefs
"Friend of the court" filings that
argue a position to judges in
cases the group didn't file
Grassroots & PAC Money
Mobilizing members and giving
campaign contributions to build
access to friendly lawmakers
Interest
Groups
Congressional
Committees
Executive
Agencies
funding & testimony
favorable regulations
budgets & oversight
Each corner helps the other two — a mutually reinforcing, hard-to-break policy relationship.

SLIDE 9 · THE ROAD TO THE WHITE HOUSE
Electing a President
1. Primaries & Caucuses
States select delegates
who support a candidate
Jan–June of election year
→
2. Conventions
Delegates formally
nominate the ticket
Summer, election year
→
3. General Election
Citizens vote for a
slate of electors
1st Tuesday, November
→
4. Electoral College
Electors cast votes;
270 wins presidency
December, formally
Open vs. Closed Primaries
Open:
Any registered voter may vote in
either party's primary
Closed:
Only voters registered with that
party may vote in its primary
Caucuses vs. Primaries
Caucus:
In-person local meetings; voters
group publicly by candidate
Primary:
Standard secret-ballot election,
run by the state — far more common
Remember: citizens don't directly elect the president — they elect electors who then vote in the Electoral College.
The Review Hub · AP Government Unit 5
SLIDE 10 · HOW WE ACTUALLY ELECT A PRESIDENT
The Electoral College
538
total electors
270
electoral votes to win
Winner-Take-All Rule
48 states + D.C. award ALL their
electoral votes to the state's
popular-vote winner.
Exceptions: Maine & Nebraska
split votes by congressional district
When the Electoral College Winner Differs From the Popular Vote
1876
Hayes over Tilden
1888
Harrison over Cleveland
2000
Bush over Gore
2016
Trump over Clinton
Critics call this a democratic legitimacy problem; supporters say it protects smaller states' voice.
A candidate can win the presidency while losing the national popular vote.

SLIDE 11 · THE CAMPAIGN MACHINE
Modern Campaigns Have Industrialized
Professional Consultants
Pollsters, ad-makers, and strategists
now run campaigns as a full-time,
paid profession — not volunteers
from the local party organization.
Rising Campaign Costs
Ads, data, travel, and staff now cost
billions per cycle nationally — driving
a nonstop fundraising treadmill for
candidates at every level of office.
Longer Election Cycles
Presidential campaigning now starts
a year or more before the first primary
vote — the "permanent campaign"
blurs the line between governing and running.
Data & Microtargeting
Voter-file analytics let campaigns send
tailored messages to narrow slices of
the electorate — a suburban parent
sees a different ad than a retiree.
Together these forces turned campaigns from local, volunteer-driven efforts into year-round professional operations.

SLIDE 12 · MONEY IN POLITICS
Campaign Finance: BCRA to Super PACs
Before 2002
Hard money (limited,
to candidates) vs. soft
money (unlimited, to parties)
2002
BCRA (McCain-Feingold)
Bans soft money to national
parties; restricts issue ads
near an election
2010
Citizens United v. FEC
Allows unlimited independent
expenditures by corporations,
unions & nonprofits
Today
PACs
• Directly connected to a candidate
• Contributions are capped by law
• May give directly to campaigns
• Regulated by the FEC
Ex: a corporation's employee PAC
Super PACs
• Legally independent of candidates
• Can raise/spend unlimited sums
• Cannot coordinate with a campaign
• Only independent expenditures
Made possible by Citizens United (2010)
Know the sequence: BCRA tightened the rules in 2002; Citizens United loosened them again in 2010.

SLIDE 13 · THE MEDIA'S ROLE
Media as a Linkage Institution
Citizens
→
Media (TV, print, digital)
Filters and frames what reaches the public
→
Government
Agenda-Setting
The media decides which stories are
"newsworthy" — shaping what issues
the public (and politicians) end up
talking and thinking about.
Doesn't tell you WHAT to think — tells
you WHAT to think ABOUT.
Horse-Race Coverage
Elections get framed like a race —
who's ahead in the polls, campaign
strategy, and momentum — rather
than the substance of policy issues.
Critics argue it crowds out coverage
of substantive policy positions.
Traditional media remains a core linkage institution — connecting citizens' awareness to government and elections.
The Review Hub · AP Government Unit 5
SLIDE 14 · THE NEW MEDIA LANDSCAPE
Changing Media & Political Participation
Partisan & Niche News
Cable and online outlets now cater to
narrow ideological audiences instead
of one shared broadcast-era audience.
Echo Chambers & Filter Bubbles
Social-media algorithms show users
more of what they already agree with,
narrowing exposure to other views.
Misinformation & Disinformation
False or misleading content spreads
quickly online, often faster than fact-
checking or official correction can catch up.
New Tools for Engagement
Social media also lowers the cost of
organizing, fundraising, and reaching
young or previously disengaged voters.
+ Mobilization
Easier to organize & spread awareness
to new participants
− Polarization
Deepens divides & makes shared facts
harder to agree on
