Political Institutions, Behavior, and Public Policy
Build the constitutional skeleton first
The exam expects you to move confidently between the Constitution, federalism, the branches, parties, elections, and policy. Know the amendment map: 13th (slavery abolished), 14th (citizenship, due process, equal protection), 15th (voting regardless of race), 16th (income tax), 17th (direct election of senators), 18th/21st (Prohibition and repeal), 19th (women's suffrage), 24th (poll tax banned in federal elections), and 26th (vote at 18). Link landmark cases to principles: Marbury v. Madison (1803) established judicial review; Plessy v. Ferguson (1896) sanctioned segregation; Brown v. Board (1954) overturned it; Engel v. Vitale (1962) applied the establishment clause to school prayer.
Parties, participation, and policy
Trace party eras and realignments: the 1932 election built the New Deal coalition around labor, urban ethnics, and African Americans; 1968 and after saw the South shift toward the GOP. Distinguish the Civil Rights Act of 1964 (public accommodations, employment) from the Voting Rights Act of 1965 (federal enforcement of voting). For policy, connect Progressive regulation, New Deal social insurance (Social Security, 1935), Great Society Medicare/Medicaid (1965), and later deregulation.
Traps and a rule of thumb
Questions often swap the 14th and 15th Amendments, or ask which branch or level of government acts. Federalism questions reward noting that states run elections and schools while the federal government uses grants and mandates. A useful rule: when an amendment question appears, identify the mechanism first (who is protected, what is banned, who gets a power), then match it to the number.
Worked example: "Which amendment gave Congress power to levy an income tax?" Mechanism = revenue power, not voting or rights. That is the 16th, not the 13th–15th Reconstruction cluster.
