AP US Government — Congress, the budget and the bureaucracy

Unit 2 of AP United States Government and Politics carries the most weight in the multiple-choice section, and much of it concerns how Congress actually works and how laws become the day-to-day actions of federal agencies. This material covers the parts of that machinery the course names specifically: the budget, the bargaining that builds majorities, district lines, the roles members play, gridlock, and the bureaucracy with its alliances and its civil service.

The quiz starts with the budget. An aging population raises Social Security and Medicare costs automatically, Congress will not change the law, and it wants to hold defense and infrastructure steady: what has to give? From there it covers pork-barrel legislation and logrolling, the conference committee, the House discharge petition, partisan gerrymandering after Rucho v. Common Cause (2019) set beside the racial gerrymandering claims that Shaw v. Reno still allows, the trustee model of representation, and gridlock under divided government. The last four questions are on the bureaucracy: an iron triangle drawn from farm policy, how issue networks differ from it, why the Pendleton Act of 1883 replaced patronage with merit, and how a president shapes an agency through the people he appoints.

The flashcards define each term, including packing and cracking, lame-duck presidents, compliance monitoring and gridlock.

The written work asks for eight short explanations of the kind the concept application question rewards: mandatory against discretionary spending and what entitlement growth does to new priorities; pork and logrolling, with the case for and against each; gerrymandering techniques and how the Court treats partisan and racial claims differently; the three models of representation in practice; divided government, gridlock and appointments; iron triangles against issue networks with an example; merit against patronage; and the tools the president and Congress each use to steer federal agencies.

The oral exam gives you a short situation (a stalled bill, a spending fight, a new district map, an agency and its allies) and asks you to name the concept and explain how it works.

The material is descriptive. Where practices are disputed, such as pork, partisan map-drawing or the growth of entitlements, the arguments on each side are set out as their supporters make them.

Explain pork-barrel legislation, logrolling, conference committees and discharge petitions
Explain gerrymandering and how the Court treats partisan and racial claims
Apply the trustee, delegate and politico models of representation

Sample question

A budget analyst notes that, as the population ages, spending on Social Security and Medicare rises automatically each year under existing law. Congress does not intend to change those laws. If it also wants to keep funding for defense and infrastructure at current levels, what must happen?

Either federal revenue must rise or the annual deficit will grow, because entitlement spending is mandatory while defense and infrastructure are discretionary items funded in yearly appropriations
Nothing, because mandatory and discretionary spending are paid from the same fixed annual appropriation that cannot be exceeded
The president must impound the extra entitlement payments, since Social Security and Medicare are discretionary programs
Defense and infrastructure will be funded automatically, because they too are mandatory spending required by permanent law

See the answer

Either federal revenue must rise or the annual deficit will grow, because entitlement spending is mandatory while defense and infrastructure are discretionary items funded in yearly appropriations

Mandatory spending, such as Social Security, Medicare and Medicaid, is required by existing law and grows with the number of eligible people unless Congress changes the law. Discretionary spending, such as defense, education and infrastructure, is set each year in appropriations bills. With entitlement law unchanged and discretionary spending held steady, total spending rises, so either tax revenue increases or the deficit grows. Entitlements are not appropriated from a fixed pot, cannot be impounded, and defense is discretionary, not mandatory.
