United States Government and Politics: Structure, Process, and Law
Core concepts
Build the constitutional frame first: enumerated Article I powers plus the necessary and proper (elastic) clause, Article II and Article III grants, the supremacy clause, and the checks that link the branches. Then federalism's phases - dual, cooperative, coercive, new - with categorical versus block grants, unfunded mandates, and devolution. For civil liberties, know selective incorporation through the Fourteenth Amendment's due process clause and the speech tests (clear and present danger, Brandenburg, Tinker, Miller). For civil rights, know the three tiers of equal protection review (strict scrutiny, intermediate, rational basis). Institutions: Congress's committee system, the House Rules Committee, Senate cloture and filibuster, apportionment and redistricting; the presidency's veto, executive orders, and unilateral tools; the bureaucracy's rulemaking and issue networks; and the judiciary's Marbury power of judicial review with restraint/activism and stare decisis. Linkage institutions - parties, elections and the Electoral College, interest groups (pluralism versus elite theory, free-rider problem), media (agenda setting, framing, priming), and public opinion - connect citizens to government.
Traps
Incorporation is selective, not total: the grand jury and quartering provisions are not applied to the states. The necessary and proper clause grants power; it does not limit it. Cloture's sixty votes is a Senate rule, not constitutional text, and each chamber faces different coalitions. Keep civil liberties (protection from government overreach) separate from civil rights (protection from discrimination). Rational basis is the most deferential test; strict scrutiny is the least.
Worked example
McCulloch v. Maryland: Congress may charter a bank under implied powers, and a state may not tax a federal instrumentality. If a question asks which clause supplied the congressional power, the answer is necessary and proper; if it asks why the state tax failed, the answer is the supremacy clause.
