Unit 2 FRQ Practice — SCOTUS Comparison
Master the AP Gov SCOTUS Comparison FRQ by comparing Baker v. Carr (1962) with Rucho v. Common Cause (2019) on justiciability, part by part.
What you'll do in this lesson
A voice-first session with the Crimsora tutor on Unit 2 FRQ Practice — SCOTUS Comparison, then targeted practice and FRQs — with the tutor adapting to where you get stuck.
What this lesson covers
The SCOTUS Comparison is one of the most predictable questions on the AP Gov exam because it always pairs one of the fifteen required cases with a case you have never read. Your job is not to memorize the second case—it's to read a short description, connect it to a shared constitutional principle, and reason across both cases. This lesson walks through a full four-part prompt comparing the required case Baker v. Carr (1962) to the nonrequired case Rucho v. Common Cause (2019), both of which turn on the idea of justiciability. You will learn exactly what each rubric point rewards, how to avoid the traps that cost students easy points, and how to write sentences that earn credit fast.
How the SCOTUS Comparison FRQ Is Built
Every SCOTUS Comparison question has four parts worth one point each, and each part maps to a specific reasoning task. The College Board gives you a paragraph describing the nonrequired case; you supply everything about the required case from memory. You are never asked to know the nonrequired case in advance.
For this prompt the shared principle is justiciability—whether a court has the authority to decide a type of dispute at all. A misconception to kill now: the shared concept is not always a clause of the Constitution. Here it is a judicial doctrine. Part A wants justiciability (or the political question doctrine), not "the Equal Protection Clause," even though Baker involved equal protection. Read what the prompt actually asks.
| Part | What it asks | What earns the point |
|---|---|---|
| A | Identify the constitutional clause/principle common to both cases | Name the shared concept accurately |
| B | Explain how facts of the required case led to its holding | Link a specific fact to the ruling |
| C | Explain how the reasoning of both cases is similar or different | Compare the two holdings on the shared principle |
| D | Describe an interaction—how the nonrequired case's holding affects an institution, or a political response | Apply the ruling to real-world power |
Part A & B — Baker v. Carr Facts, Holding, and the Shared Concept
Tennessee had not redrawn its state legislative districts since 1901 despite decades of population shifts toward cities. Charles Baker argued that rural districts with far fewer people held the same number of seats as crowded urban districts, diluting urban votes and violating the Fourteenth Amendment's Equal Protection Clause. The core legal question was procedural: could federal courts even hear a redistricting complaint, or was apportionment a political question reserved for legislatures?
The Supreme Court held that legislative apportionment challenges ARE justiciable—federal courts may hear them. This opened the door to later "one person, one vote" rulings.
For Part A, name the shared concept: both cases concern justiciability, specifically whether redistricting claims present a political question that courts must avoid.
For Part B, you must connect a fact to the holding, not just state the holding. Strong sentence: "Because Tennessee's failure to reapportion since 1901 left urban voters with diluted votes under the Equal Protection Clause, the Court held the claim was justiciable and could be decided by federal courts." The graders want cause and effect—the fact () producing the ruling (). Simply writing "the Court ruled it was justiciable" with no fact will not earn the point.

Part C — How the Reasoning Differs
This is the part students most often lose, because they describe both holdings separately instead of comparing the reasoning about the shared principle. In Baker v. Carr, the Court reasoned that malapportionment claims under the Equal Protection Clause provide judicially manageable standards, so they are justiciable—courts CAN act. In Rucho v. Common Cause, the Court reasoned that claims of purely partisan gerrymandering present a nonjusticiable political question because there is no clear, neutral standard for deciding how much partisanship is too much. So courts CANNOT act.
The contrast is sharp and testable:
A point-earning sentence: "Baker found redistricting justiciable because equal-population claims have manageable standards, whereas Rucho found partisan gerrymandering nonjusticiable because the Court said no manageable standard exists to measure excessive partisanship." Use the word "whereas" or "while" to force yourself into an actual comparison. If you only describe Rucho, you get zero on Part C even if the description is perfect.
The contrast is sharp and testable:
| Baker v. Carr (1962) | Rucho v. Common Cause (2019) | |
|---|---|---|
| Type of claim | Population malapportionment | Partisan gerrymandering |
| Manageable standard? | Yes (equal population) | No |
| Result | Justiciable | Nonjusticiable |
Part D — Effect on State Legislatures' Power
Part D asks you to explain how Rucho's holding affects state legislatures' power over districting. Because the Court declared partisan gerrymandering a political question beyond federal court review, federal courts will not strike down district maps drawn to benefit the party in power. The practical effect: state legislatures gain freedom to draw partisan maps without fear of federal judicial intervention on partisanship grounds.
A complete answer names the actor, the mechanism, and the consequence: "Because Rucho barred federal courts from hearing partisan gerrymandering claims, state legislatures that control redistricting can draw maps favoring their own party without federal courts overturning them, increasing legislative power over election outcomes."
Watch the boundaries. Rucho did NOT legalize racial gerrymandering (still reviewable) and did NOT block state courts or state constitutions from acting—several states now police gerrymandering through state courts or independent commissions. On the exam you don't need those nuances to earn the point, but they prevent overclaiming. The point is earned by showing the ruling shifts power toward the legislatures that already draw the lines. Avoid vague answers like "it affects democracy"—name state legislatures and their districting power explicitly.

Writing Fast and Clean Under Time Pressure
You have roughly 20 minutes for a SCOTUS Comparison. Do not write an introduction or conclusion—label your answers A, B, C, D and answer each directly. The graders scan for the specific reasoning, so front-load it.
A reliable template per part: state the answer, then justify with a fact or comparison word. For Part B use "because." For Part C use "whereas" or "while." For Part D use "because... state legislatures can..."
Common point-killers to avoid: answering the wrong shared concept (writing about the Equal Protection Clause when the prompt names justiciability); describing both cases in Part C without comparing them; restating the holding in Part B without a fact; and being too vague in Part D. Also remember every part is independent—a wrong Part A does not cost you Parts B through D, so keep answering even if unsure.
Finally, precision beats length. A crisp two-sentence answer that names justiciability, the manageable-standards contrast, and the shift of power to state legislatures will outscore a page of general commentary about gerrymandering being unfair.

Key terms
- Justiciability.
- Whether a dispute is of a type that courts have the authority to decide, as opposed to a matter left to the political branches.
- Political Question Doctrine.
- A principle that courts will not decide issues the Constitution assigns to Congress or the executive, or that lack judicially manageable standards; such issues are nonjusticiable.
- Malapportionment.
- The unequal distribution of population among legislative districts, so that some voters' ballots carry more weight than others.
- Redistricting / Apportionment.
- The process of drawing legislative district boundaries and allocating representation, typically controlled by state legislatures.
- Partisan Gerrymandering.
- Drawing district lines to give one political party a systematic advantage in elections.
- Judicially Manageable Standards.
- Clear, neutral criteria a court can use to decide a case; their absence can make a claim nonjusticiable, as in Rucho.
- One Person, One Vote.
- The principle that legislative districts should contain roughly equal populations so each vote counts equally; enabled by Baker v. Carr.
Worked example
In Rucho v. Common Cause (2019), voters challenged congressional maps in North Carolina and Maryland, arguing the maps were drawn to entrench the majority party. The Supreme Court held that claims of partisan gerrymandering present a nonjusticiable political question because the Constitution provides no clear standard for judging when partisanship goes too far. Based on the information above, respond to A–D. (A) Identify the constitutional principle common to both Baker v. Carr and Rucho v. Common Cause. (B) Explain how the facts of Baker v. Carr led to its holding. (C) Explain how the reasoning about that shared principle differs between the two cases. (D) Explain how the holding in Rucho v. Common Cause affects the power of state legislatures over districting.
Part A: Both cases turn on justiciability—whether federal courts have authority to decide redistricting disputes or whether they are political questions. Naming justiciability (or the political question doctrine) earns the point.
Part B: State a fact and connect it to the ruling. Tennessee had not reapportioned its legislature since 1901, so growing urban districts held the same number of seats as shrinking rural ones, diluting urban votes under the Equal Protection Clause. Because of this malapportionment, the Court held that the claim WAS justiciable and federal courts could hear reapportionment cases. The fact () produces the holding.
Part C: Compare, don't just describe. In Baker, the Court reasoned that equal-population claims offered manageable standards, so redistricting was justiciable; whereas in Rucho, the Court reasoned that partisan gerrymandering lacked any manageable standard for measuring excessive partisanship, making it nonjusticiable. The reasoning moves from courts CAN act to courts CANNOT act.
Part D: Because Rucho closed federal courts to partisan gerrymandering claims, state legislatures that control map-drawing can draw partisan maps favoring their own party without federal courts striking them down, expanding legislative control over election outcomes.
Each part answered directly and labeled would score 4 out of 4.

Practice questions
In a SCOTUS Comparison prompt pairing Baker v. Carr with Rucho v. Common Cause, which statement best identifies the shared principle the question is targeting?
- Both cases interpret the Commerce Clause
- Both cases concern whether the dispute is justiciable in federal court
- Both cases apply the Establishment Clause
- Both cases expand the president's war powers
Answer: Both cases concern whether the dispute is justiciable in federal court
Although Baker involved the Equal Protection Clause, the linking concept between the two cases is justiciability—whether federal courts may decide the type of redistricting claim at all. Baker found reapportionment claims justiciable; Rucho found partisan gerrymandering claims nonjusticiable. The Commerce, Establishment, and war-powers options have no connection to either case.
Explain the difference in reasoning between Baker v. Carr and Rucho v. Common Cause regarding justiciability, and explain how Rucho affects state legislatures.
Answer: Baker held that malapportionment claims are justiciable because equal-population standards are judicially manageable, while Rucho held that partisan gerrymandering is nonjusticiable because no manageable standard exists to measure excessive partisanship. Because Rucho bars federal courts from hearing partisan gerrymandering claims, state legislatures can draw partisan maps without federal court intervention, increasing their power over districting.
A full-credit response must actually contrast the two rulings using a comparison word such as 'while' or 'whereas' rather than describing them separately. The Rucho effect must name the actor (state legislatures) and the consequence (freedom to draw partisan maps free of federal review). Vague statements like 'it hurts fairness' would not earn the interaction point.
A student writes for Part B: 'In Baker v. Carr, the Supreme Court ruled that the case was justiciable.' Why would this response likely NOT earn the point, and how should it be fixed?
Answer: It states the holding but includes no fact from the case, so it fails to explain how the facts produced the holding. It should add a fact—Tennessee had not reapportioned since 1901, diluting urban votes—and connect it to the ruling with 'because.'
Part B specifically rewards a causal link between a case fact and the holding. Merely restating the outcome is insufficient. Adding the malapportionment fact and the word 'because' converts the sentence into a cause-and-effect explanation that earns credit.
FAQ
- Do I need to have read Rucho v. Common Cause before the exam?
- No. The SCOTUS Comparison always provides a description of the nonrequired case in the prompt. You only need to know the required case—here, Baker v. Carr—from memory and then reason across both cases using the information given.
- What is the shared concept between Baker v. Carr and Rucho v. Common Cause?
- Justiciability, also framed as the political question doctrine—whether federal courts have authority to decide a redistricting dispute. Baker found reapportionment claims justiciable; Rucho found partisan gerrymandering nonjusticiable.
- How is the SCOTUS Comparison scored?
- It is worth four points, one per part (A, B, C, D). Each part is graded independently, so a mistake on one part does not cost you the others. Answer every part directly and label them.
- What is the most common mistake on Part C?
- Describing both cases separately instead of comparing them. Part C requires you to explain how the reasoning is similar or different, so use a comparison word like 'whereas' and directly contrast the manageable-standards reasoning in Baker with the lack of a standard in Rucho.
