Gerrymandering is the intentional drawing of electoral district boundaries to favor one political party or group, creating safe seats and distorting representation; the Supreme Court has limited racial gerrymandering through equal protection challenges (Shaw v. Reno).
Gerrymandering is when the people in charge of redistricting (usually state legislatures) draw district lines on purpose to benefit one party or group. The two classic moves are "packing" (cramming the other party's voters into one district so they waste votes) and "cracking" (splitting them across many districts so they can't win any). The result is a map where the outcome is basically decided before anyone votes.
In the CED, gerrymandering shows up in Topic 2.3 as one of the forces shaping congressional behavior. Gerrymandered districts create safe seats, and safe seats reward members of Congress who play to their party base instead of the middle. That feeds partisan voting, polarization, and gridlock. The Supreme Court has stepped in partially. Baker v. Carr (1962) opened the door to equal protection challenges to redistricting, and Shaw v. Reno (1993) ruled that drawing districts primarily based on race violates the Equal Protection Clause.
Gerrymandering lives in Topic 2.3 (Congressional Behavior) under learning objective AP Gov 2.3.A, which asks you to explain how election processes, partisanship, and divided government influence how Congress acts. The essential knowledge is direct about it: gerrymandering, redistricting, and unequal representation have been "partially addressed" by Supreme Court cases that opened the door for equal protection challenges. It also feeds Topic 3.12 (AP Gov 3.12.A), where the Court has both protected and limited minority rights, including cases that prohibit majority-minority districting. And it matters for Topic 5.9 (AP Gov 5.9.A), because rigged district lines amplify the incumbency advantage in congressional elections. In short, this one term ties together institutions (Unit 2), civil rights (Unit 3), and political participation (Unit 5), which is exactly the kind of cross-unit reasoning FRQs reward.

Redistricting and Baker v. Carr (Unit 2)
Redistricting is the legal, required process of redrawing lines after each census. Gerrymandering is redistricting done with an agenda. Baker v. Carr (1962) made redistricting a question federal courts could actually hear, establishing the "one person, one vote" path for equal protection challenges to badly drawn maps.
Shaw v. Reno and Minority Rights (Unit 3)
In Shaw v. Reno (1993), North Carolina drew a majority-minority district to boost Black representation, and the Court struck it down as racial gerrymandering under the Equal Protection Clause. This is the CED's example of the Court limiting majority-minority districting, even when the goal was to help a minority group.
Political Polarization and Gridlock (Unit 2)
Safe, gerrymandered districts mean the real contest is the primary, not the general election. Primary voters tend to be more ideological, so members of Congress drift toward the extremes. That's a direct cause-and-effect chain from district lines to polarization to gridlock.
Incumbency Advantage in Congressional Elections (Unit 5)
One reason House incumbents win reelection at extremely high rates is that many of them run in districts drawn to be safe for their party. Gerrymandering is part of why congressional elections are often uncompetitive even when the country as a whole is closely divided.
Multiple-choice questions usually test gerrymandering through its consequences and its case law. Expect stems about why congressional voting has polarized over recent decades, what principle Baker v. Carr (1962) established for redistricting challenges, and why Shaw v. Reno (1993) found racial gerrymandering unconstitutional under the Equal Protection Clause. You should be able to do three things: define packing and cracking, explain the causal chain from gerrymandered districts to safe seats to polarization and gridlock (AP Gov 2.3.A), and distinguish what the Court allows (partisan considerations) from what it forbids (race as the predominant factor in drawing lines). Gerrymandering is also a natural fit for the Concept Application FRQ, like the 2018 SAQ on how parties seek to win elections to control government, and for SCOTUS comparison questions involving Shaw v. Reno, one of the required cases.
Redistricting is the neutral, constitutionally required process of redrawing district boundaries after each decennial census to keep districts roughly equal in population. Gerrymandering is the manipulation of that process to advantage a party or group. Every gerrymander happens through redistricting, but not all redistricting is gerrymandering. On the exam, use "redistricting" for the process and "gerrymandering" for the abuse of it.
Gerrymandering means drawing district lines on purpose to favor one party or group, usually through packing (concentrating opposition voters in one district) or cracking (splitting them across many).
Baker v. Carr (1962) opened the door for equal protection challenges to redistricting and established that federal courts can rule on these cases.
Shaw v. Reno (1993), a required SCOTUS case, held that racial gerrymandering violates the Equal Protection Clause, even when the district was drawn to create majority-minority representation.
Gerrymandering creates safe seats, which push members of Congress toward their party's base and contribute to polarization and gridlock (AP Gov 2.3.A).
Gerrymandering helps explain the incumbency advantage in House elections, since many representatives run in districts engineered to be safe for their party.
The Court has constrained racial gerrymandering but has been far more hands-off about purely partisan gerrymandering, which is why the CED says the problem is only 'partially addressed.'
Gerrymandering is the deliberate manipulation of electoral district boundaries to favor one political party or group, typically through packing and cracking voters. It appears in Topic 2.3 as a cause of safe seats, polarization, and gridlock in Congress.
Not always. Racial gerrymandering violates the Equal Protection Clause under Shaw v. Reno (1993), but purely partisan gerrymandering has not been struck down the same way. That's why the CED says Supreme Court cases have only 'partially addressed' gerrymandering.
Redistricting is the required redrawing of district lines after each census so districts have roughly equal populations. Gerrymandering is when that process is abused to give one party or group an advantage. All gerrymandering happens through redistricting, but redistricting itself is legitimate.
Baker v. Carr (1962) established that courts can hear redistricting challenges at all, creating the 'one person, one vote' principle. Shaw v. Reno (1993) applied equal protection to strike down a North Carolina district drawn primarily along racial lines. Baker is about whether courts can act; Shaw is about what maps they'll reject.
Gerrymandered districts are safe for one party, so the only race that matters is the primary. Primary voters are more ideological, so candidates move toward the extremes to win them. The result is more partisan voting and gridlock, which is exactly the chain AP Gov 2.3.A asks you to explain.
