In Intro to American Government, it is a gerrymandering strategy that shapes election outcomes and representation. ## What It Is Packing is a gerrymandering tactic in Intro to American Government where a mapmaker puts a large number of voters from one party, race, or other political group into the same district. The goal is not to give that group extra power, but to reduce its influence in neighboring districts by wasting those votes in one place. The basic logic is simple. If one district becomes overwhelmingly Democratic or overwhelmingly Republican, that district will usually elect the packed group’s preferred candidate by a huge margin. That leaves fewer of those voters spread across nearby districts, which can make the surrounding districts more competitive for the other party. Packing is usually discussed during redistricting, when district lines are redrawn after a census or after a court order. Because district maps can change who votes with whom, the way lines are drawn can affect which party wins seats in a legislature or in Congress. A district that looks “fair” on paper may still be engineered to protect one party if its voters were packed together on purpose. This is why packing is one of the classic tools of gerrymandering. It does not always create more seats by itself, but it can help a party lock in a safe seat while weakening opposition voters across multiple other districts. In practice, that can make representation less responsive, because election results may reflect map design as much as voter preference. A quick example helps: imagine a city split into three congressional districts. If 80% of one party’s supporters are packed into District 1, that party wins District 1 easily, but it may lose Districts 2 and 3 because the remaining supporters were spread too thin. The party wins one seat big and loses the other two, even if it had a strong overall vote share in the area. Packing also shows why district maps matter so much in Congress. Since members of the House represent districts, the way districts are drawn can shape who gets represented, how safe a seat is, and how much competition voters actually see at the ballot box. ## Why It Matters Packing matters because it shows how district design can shape congressional representation before a single vote is cast. In Intro to American Government, this term sits right inside the study of Congress, elections, and redistricting, where you are asked to think about how institutions translate votes into seats. It also helps you spot a common pattern in political maps. If a district has one huge cluster of voters from a party and several surrounding districts that lean the opposite way, packing may be part of the reason. That makes it easier to explain why one party can win more seats even when the statewide vote is close. The term is also useful when you are reading about fairness, voting rights, or court challenges to district maps. Packing raises questions about representation, because it can concentrate a group’s political power instead of spreading it across multiple districts. That can affect whether elections feel competitive or already decided. When you see packing in a case study, the main move is to ask who got concentrated, who got diluted, and how that changes the balance of power. ## Connections ### Gerrymandering Packing is one of the main techniques used in gerrymandering. Gerrymandering is the broader practice of drawing district lines to advantage a party or group, while packing is the move of loading many target voters into one district so their influence is weaker elsewhere. ### Cracking Cracking is the opposite strategy from packing. Instead of concentrating a group into one district, mapmakers split that group across several districts so it cannot form a majority anywhere. On map questions, packing and cracking often work together in the same plan. ### Redistricting Packing usually happens during redistricting, when district boundaries are redrawn after population changes or legal changes. Redistricting is the process, and packing is one way political actors can use that process to shape election results. ### [Party Leadership](/fundamentals-american-government/key-terms/party-leadership) Party leadership may push for district maps that use packing to protect incumbents or create safe seats. That connection matters because leadership wants more seats, and safe districts can make it easier to keep party control in Congress. ## On the AP Exam A map question or short-answer prompt may ask you to identify packing from a district diagram, vote pattern, or written description. Look for a district where one party or demographic is concentrated heavily in one place, leaving nearby districts less favorable for that group. The key move is to explain the effect, not just name the tactic: one district becomes a safe seat while surrounding districts become easier for the other side to win. If you get a case about redistricting or gerrymandering, connect packing to representation. Say how the map changes the translation of votes into seats, and whether it reduces competition. In discussion posts or essays, you may also compare packing with cracking to show you understand the difference between concentrating voters and splitting them apart. ## Packing vs Cracking Packing and cracking are both gerrymandering tools, but they work in opposite ways. Packing concentrates a group of voters into one district, while cracking spreads that group across several districts so it cannot win many seats. If a question says voters are being split up, that is cracking, not packing. ## Key Takeaways - Packing is a redistricting tactic that concentrates a group of voters into one district to limit their influence elsewhere. - It is one of the classic tools of gerrymandering and often creates a very safe seat for the packed group’s party. - Packing can make nearby districts more favorable to the opposite party because it removes those voters from the competition. - The concept matters in Congress because district design affects who gets represented and how competitive elections really are. - If you are identifying packing, look for one district with an unusually large concentration of a party or demographic group. ## FAQs ### What is packing in Intro to American Government? Packing is when mapmakers draw district lines so that many voters from one party or group are concentrated in a single district. That district becomes overwhelmingly supportive of that group, while neighboring districts become easier for the opposite side to win. ### How is packing different from cracking? Packing puts voters together in one district, while cracking splits them across several districts. Both are gerrymandering tactics, but packing wastes votes in one place and cracking weakens a group by spreading its support too thin. ### Why do politicians use packing? They use packing to protect their own party’s overall advantage. By making one district very safe for the other side, they can sometimes improve their chances in nearby districts and increase the number of seats they win. ### How do I spot packing on a district map? Look for a district that has a huge concentration of one party or demographic group, often much higher than the surrounding districts. If the map seems to bunch that group into one oddly shaped or unusually lopsided district, packing may be happening. ## Related Study Guides - [11.1 The Institutional Design of Congress](/fundamentals-american-government/unit-11/1-institutional-design-congress/study-guide/xqPLdHkw1wxLGtfn) ## About This Document Canonical Fiveable pages are available as Markdown at the same path plus `.md`. - [llms.txt](https://fiveable.me/llms.txt): index of Fiveable's sections and URL patterns - [llms-full.txt](https://fiveable.me/llms-full.txt): complete subject and unit listing - [MCP server](https://fiveable.me/mcp): call Fiveable as tools instead of fetching pages (`https://fiveable.me/api/mcp`) - [MCP server for AP teachers](https://fiveable.me/mcp/teachers): a teacher's classes, assignments and AP-rubric grading (`https://fiveable.me/api/mcp/teacher`) ## Structured Data ```json {"@context":"https://schema.org","@graph":[{"@type":"LearningResource","@id":"https://fiveable.me/fundamentals-american-government/key-terms/packing#resource","name":"Packing in Intro to American Government","url":"https://fiveable.me/fundamentals-american-government/key-terms/packing","learningResourceType":"Concept explainer","educationalLevel":"AP® / High School","about":{"@id":"https://fiveable.me/fundamentals-american-government/key-terms/packing#term"},"audience":{"@type":"EducationalAudience","educationalRole":"student"},"dateModified":"2026-07-03T02:21:37.778Z","isPartOf":{"@type":"Collection","name":"Intro to American Government Key Terms","url":"https://fiveable.me/fundamentals-american-government/key-terms"},"author":{"@type":"Organization","@id":"https://fiveable.me/editorial#content-team","name":"Fiveable Content Team","url":"https://fiveable.me/editorial","parentOrganization":{"@id":"https://fiveable.me/#organization"},"member":[{"@type":"Person","name":"Amanda DoAmaral","sameAs":["https://www.linkedin.com/in/adoamaral"]},{"@type":"Person","name":"Becky Bahr","sameAs":["https://www.linkedin.com/in/becky-bahr-b52743132"]}]},"publisher":{"@type":"Organization","name":"Fiveable","url":"https://fiveable.me"}},{"@type":"DefinedTerm","@id":"https://fiveable.me/fundamentals-american-government/key-terms/packing#term","name":"Packing","description":"Packing is a redistricting tactic where mapmakers concentrate many voters from one party or group into one district.
