What citizens must do, how elections work, and the cases the EOC repeats.
Who is a citizen, and what is required
The 14th Amendment says people born or naturalized in the United States, and subject to its jurisdiction, are citizens. Naturalization is the legal process for immigrants who qualify: time as a lawful resident, good moral character, knowledge of civics and English, and an oath.
Obligations are things you must do: obey laws, pay taxes, serve on a jury if called, and register for Selective Service if you are a male citizen or male immigrant in the required age range. Responsibilities are things you should do: vote, stay informed, speak up peacefully, and serve the community.
Remember: Jury duty and taxes are obligations. Voting is a responsibility, not a legal requirement.
Parties, interest groups, media, bias
Political parties organize people who share a broad approach to government. They recruit candidates, inform voters, and act as a watchdog when they are out of power. The United States has two major parties, but third parties can still shift the debate.
Interest groups try to influence policy on a narrower cause. Lobbying is their direct contact with lawmakers. A PAC (political action committee) raises money to support candidates.
Media — news, social platforms, campaigns — shape what people notice. Bias means a one-sided slant. Propaganda uses loaded language, symbols, or half-truths to push a view. A good citizen compares sources.
Elections and qualifications
The 15th, 19th, 24th, and 26th Amendments removed barriers based on race, sex, poll taxes, and age over 18. States still run elections and can set neutral rules like registration deadlines.
Presidential elections use the Electoral College. Each state gets electors equal to its senators plus representatives. Most states give all their electors to the statewide popular-vote winner.
Cases worth memorizing
Marbury v. Madison (1803) — judicial review.
McCulloch v. Maryland (1819) — implied powers and supremacy.
Plessy v. Ferguson (1896) — allowed “separate but equal.” Brown v. Board of Education (1954) — overturned that in public schools; separate is inherently unequal.
Gideon v. Wainwright (1963) — states must provide a lawyer if you cannot afford one in a serious criminal case. Miranda v. Arizona (1966) — police must tell suspects their rights before custodial questioning.
In re Gault (1967) — juveniles accused of crimes get due process, including notice and a lawyer. United States v. Nixon (1974) — the president is not above the law; executive privilege has limits. Bush v. Gore (2000) — the Court ended Florida’s recount, deciding the 2000 presidential election.
District of Columbia v. Heller (2008) — the 2nd Amendment protects an individual right to keep a firearm for lawful purposes like self-defense in the home.
Remember: Brown ended school segregation. Gideon = lawyer. Miranda = warnings. Nixon = no one is above the law.
