Candidate‑Centered Campaigns: TV & internet → weaken party apparatus.
Interest Groups & Lobbying
Activities: direct lobbying, grassroots mobilization, PAC funding, amicus briefs.
Inequalities: free‑rider problem → solved by selective benefits.
Iron Triangle Example:
Agriculture Committee ↔ USDA ↔ Farm Bureau Federation → crop subsidies stable decades.
Campaign Finance
Law / Case | Impact |
|---|---|
FECA (1971) | Created FEC; set donation limits, disclosure. |
Buckley v. Valeo (1976) | Spending = speech; candidate limits struck down; donor limits ok. |
BCRA (2002) | Banned soft money; electioneering ad limits. |

If no majority: House chooses President (one vote per state); Senate chooses VP.

Incumbency Advantage: visibility, constituent services, franking, PACS, redistricted safety.
Media’s Political Role
Function | Description | Risk |
|---|---|---|
Gatekeeper | Decides what’s newsworthy. | Agenda bias. |
Scorekeeper | “Horse‑race” elections. | Focus on polls > policy. |

🧠 Quick Connections Matrix
Theme | Documents / Cases | Core Question Framed As |
|---|---|---|
Federal Power v States | McCulloch v Maryland, U.S. v Lopez, Federalist 51 | How should power be divided? |
Representation & Participation | Fed 10, Brutus 1, Constitution Art I | How is citizen voice reflected? |

Short “Think‑Like‑a‑Scholar” Tips
Always attach clauses: don’t just say “violated rights,” name “Due Process Clause” or “Commerce Clause.”
Cite both case & principle when drawing parallels.
Use comparative phrasing (“unlike Lopez, Congress in McCulloch was upholding ...”).
For argument essays, phrase thesis as policy principle (“Madisonian structural checks best secure liberty because …”).
