The Deliberate Distortion of Democracy

Gerrymandering is the deliberate manipulation of political district boundaries to achieve an unfair electoral advantage for a particular party or group. While the practice is as old as representative government itself, modern technology and hyper-partisan politics have turned it into a surgical tool that can effectively decide election outcomes before a single vote is cast. At its core, gerrymandering undermines the principle that each citizen’s vote should carry equal weight and that elected representatives should reflect the broad will of the people. Instead, it allows map drawers—often state legislators—to choose their voters, rather than letting voters choose their representatives.

The term “gerrymander” dates back to 1812, when Massachusetts Governor Elbridge Gerry signed a redistricting plan designed to favor his Democratic-Republican Party. One of the new districts in Essex County was said to resemble a salamander, and a newspaper editor coined the portmanteau “gerrymander.” The name stuck, and the practice has been a recurring feature of American politics ever since. Although both major parties have engaged in gerrymandering, its prevalence and sophistication have escalated dramatically in recent decades, thanks to powerful mapping software and a Supreme Court ruling that effectively removed federal judicial oversight of partisan gerrymandering.

How Gerrymandering Works: The Four Core Techniques

At its most basic level, gerrymandering uses two primary strategies—packing and cracking—along with more targeted maneuvers like hijacking and kidnapping. Each technique serves to dilute the voting power of certain groups while concentrating the influence of the party in power.

1. Packing

Packing means cramming as many voters of the opposing party as possible into a small number of districts. The goal is to create a few overwhelmingly “safe” seats for the opposition while wasting their surplus votes. For example, if a state has 40% Democratic voters and 60% Republican voters, a packer might place all Democratic voters into three districts, each with 80% Democratic registration. Those three districts will be won easily by Democrats, but the seven remaining districts will be heavily Republican. The result: Republicans win 70% of the seats with only 60% of the vote, while Democrats win only 30% of the seats with 40% of the vote.

2. Cracking

Cracking is the reverse of packing. Instead of concentrating the opposition, map drawers spread their supporters thinly across many districts so that they cannot form a majority anywhere. This technique is especially effective when the opposition party’s voters are geographically dispersed. For instance, if Democratic voters are distributed evenly across a state, cracking might ensure that every district is 51% Republican and 49% Democratic, delivering a clean sweep of all seats for the party in power.

3. Hijacking and Kidnapping

These are less common but equally manipulative techniques. Hijacking occurs when an incumbent’s home address is drawn into a district already represented by another incumbent from the same party, forcing two incumbents of the same party to compete against each other. This weakens the party’s overall representation or eliminates a troublesome member. Kidnapping moves an incumbent’s home into a district that is heavily skewed toward the opposing party, making it extremely difficult for that incumbent to win reelection. Both methods are used to punish or neutralize specific politicians without relying on voters.

Why Gerrymandering Is a Deep Problem for Democracy

Gerrymandering doesn’t just help one party win more seats—it fundamentally corrupts the relationship between voters and their government. The consequences ripple through every level of the political system.

Eliminating Competitive Elections

When districts are “safe” for one party, general elections become meaningless. In many gerrymandered districts, the real contest happens in the primary, where turnout is low and candidates cater to the most extreme elements of their party. This pushes both parties to the fringes, intensifying political polarization. According to a 2022 analysis by the Brennan Center for Justice, fewer than 10% of U.S. House seats were considered competitive in districts drawn after the 2020 census. That lack of competition means incumbents face little accountability, and voters have no genuine choice in November.

Disproportionate Representation

Gerrymandering allows a party to win a majority of seats even when it loses the popular vote. In the 2018 U.S. House elections, Democrats won the national popular vote by 8.6 percentage points but only secured a 235–199 seat advantage—a gap that was narrower than it should have been, largely due to Republican-drawn maps in states like Ohio, North Carolina, and Wisconsin. In extreme cases, a party that wins only 45% of the statewide vote can capture 60–70% of the legislative seats. This violates the basic democratic principle of majority rule and erodes public trust in the system.

Silencing Minority Communities

While the Voting Rights Act of 1965 requires that districts not dilute the voting power of racial or language minorities, partisan gerrymandering can still harm minority communities. Packing large numbers of minority voters into a single district may technically create a “majority-minority” district, but it also reduces their influence in surrounding districts. In some cases, map drawers intentionally “crack” minority communities across multiple districts to weaken their collective political power. This practice, known as racial gerrymandering, has been repeatedly struck down by courts, but proving racial intent (as opposed to partisan intent) remains challenging.

Entrenching Incumbents and Reducing Accountability

When legislators can draw their own district lines every ten years, they have a powerful incentive to protect themselves. Incumbents in safe districts face little risk of defeat, which can lead to complacency, reduced responsiveness, and a focus on partisan goals rather than constituent needs. A 2019 study by the University of California, Irvine found that gerrymandered districts increase the likelihood that legislators will vote along party lines and ignore public opinion on issues like healthcare, taxes, and climate change.

Historical and Modern Examples

The Original Salamander: Massachusetts 1812

The first gerrymander was created by Governor Elbridge Gerry to help his party win state senate seats. The famous cartoon depicting the long, twisted district as a salamander appeared in the Boston Gazette. Although Gerry himself later expressed regret over the map, the tactic caught on and became a standard tool of political warfare.

North Carolina’s Extreme Partisan Maps

In the 2010s, North Carolina Republicans drew some of the most aggressive partisan maps in the country. In 2012, despite receiving only 49% of the statewide vote for U.S. House candidates, Republicans won 9 of the state’s 13 seats (69%). After multiple court challenges, a federal court struck down two congressional districts as unconstitutional racial gerrymanders in 2017. However, a subsequent map drawn in 2021 was also challenged, leading to a 2022 state supreme court ruling that found the maps violated the state constitution’s free elections clause. The case illustrates the ongoing battle between partisan map drawers and courts.

Wisconsin: The “8-6” Trick

In Wisconsin, Republican map drawers in 2011 produced a state assembly plan that allowed them to win 60 of 99 seats (61%) with only 48.6% of the two-party vote. A federal district court struck down the plan as an unconstitutional partisan gerrymander in 2016 (Gill v. Whitford), but the U.S. Supreme Court ultimately avoided the partisan gerrymandering question by ruling that the plaintiffs lacked standing. The Wisconsin example remains a textbook case of how cracking can produce extreme partisan advantages.

Maryland: A Democratic Example

Partisan gerrymandering is not a Republican monopoly. In Maryland, Democrats drew a congressional map in 2011 that packed Republican voters into one district while spreading Democrats across the others. The result: Democrats won 7 of 8 U.S. House seats with 60% of the vote, even though Republicans had around 35% of the statewide vote. In 2018, a federal court ruled the map an unconstitutional partisan gerrymander, but the Supreme Court reversed on appeal, again avoiding the core issue.

The Supreme Court’s Hands-Off Approach

In a landmark 2019 decision, Rucho v. Common Cause, the U.S. Supreme Court held that partisan gerrymandering claims are “nonjusticiable” — meaning federal courts cannot hear them because there are no “manageable standards” for adjudicating them. This decision effectively closed the door to federal lawsuits based solely on partisan advantage, shifting the burden entirely to state courts, legislatures, and voters. Since Rucho, state courts in states like Ohio, North Carolina, Pennsylvania, and New Mexico have taken up the fight, often finding partisan gerrymanders violate state constitutions.

Independent Redistricting Commissions

Several states have moved to take redistricting power away from partisan legislators and give it to independent or bipartisan commissions. The best-known examples are Arizona and California, which use citizen-led commissions to draw congressional and state legislative maps. In 2018, Michigan, Colorado, and Utah passed ballot measures establishing independent commissions. Studies show that commission-drawn maps produce more competitive districts and better represent the partisan makeup of the state. The National Conference of State Legislatures maintains a detailed list of redistricting commission models. (Source: NCSL)

Algorithmic and Mathematical Redistricting

Progressive reformers have proposed using computers to draw districts based on neutral criteria like compactness, contiguity, and preservation of communities of interest, while ignoring partisan data. Tools like the “Bipartisan Gerrymandering Algorithm” developed by researchers at Duke University can generate thousands of nonpartisan maps, allowing voters to compare them against the official plan. Some states, like Virginia, now require that map drawers use open data and publicly justify every deviation from neutral principles. However, critics argue that even “neutral” algorithms can embed bias if the criteria are chosen strategically.

Anti-Gerrymandering Court Cases

Legal challenges continue in state courts. In 2023, the Ohio Supreme Court struck down four consecutive sets of Republican-drawn maps as unconstitutional, leading to a stalemate that forced the use of court-ordered maps for the 2022 elections. Similarly, the Pennsylvania Supreme Court threw out the state’s congressional map in 2018, citing partisan advantage. These state-level victories show that while federal courts may be closed, state courts can still provide a remedy under state constitutions. (Brennan Center analysis)

Broader Impact on American Democracy

Beyond the immediate effects on representation, gerrymandering fuels voter cynicism, deepens polarization, and makes government less responsive. When voters feel their voice doesn’t matter because their district is a foregone conclusion, turnout drops. A 2020 study in the Journal of Politics found that voters in heavily gerrymandered districts are significantly less likely to believe their vote influences government. That erosion of trust can have cascading effects, including lower participation in elections, less civic engagement, and a greater willingness to support anti-democratic candidates.

Gerrymandering also incentivizes incumbent legislators to focus on primary challengers rather than general election voters, encouraging them to adopt more extreme positions. This dynamic contributes to the gridlock that plagues Congress and state legislatures. The inability to pass popular policies like expanded background checks or infrastructure funding is often a direct consequence of representatives who are more worried about a primary challenge from the far right or far left than about losing a general election in a safe district.

There is also a racial dimension that cannot be ignored. The Voting Rights Act prohibits racial gerrymandering, but the line between partisan and racial manipulation can blur. In Shelby County v. Holder (2013), the Supreme Court struck down the preclearance formula that required jurisdictions with a history of discrimination to get federal approval before changing voting procedures. That decision opened the door for renewed racial gerrymandering, particularly in southern states. A 2022 report by the Leadership Conference on Civil and Human Rights found that many of the most aggressively gerrymandered maps also diluted Black and Latino voting power.

Moreover, gerrymandering can undermine the principle of “one person, one vote” by creating districts with wildly different populations. Although the Supreme Court has required districts to be roughly equal in population, small deviations are allowed, and map drawers can use those deviations to shift the balance of power. In some cases, districts have been drawn that are only a few hundred people apart, but the partisan advantage is enormous.

The Future: Can Gerrymandering Be Defeated?

The fight against gerrymandering is far from over. While the Supreme Court has shut the door on federal partisan gerrymandering suits, state-level litigation and reform efforts have gained momentum. Ballot initiatives are one of the most powerful tools—voters in Michigan, Colorado, and Virginia have all passed measures to create independent commissions. However, these commissions are not perfect: they can still be captured by partisan appointees, and the criteria they use may produce maps that still favor one party.

Technology offers both solutions and risks. Machine learning algorithms can draw neutral maps, but they can also be used to identify optimal gerrymanders faster than ever. The key is to ensure that redistricting is transparent, with public hearings and open data. Some advocates have called for a federal anti-gerrymandering law, such as the Freedom to Vote Act, which would require states to follow specific criteria, but such legislation faces steep odds in a divided Congress.

Another proposal is to use multi-member districts with proportional representation, which would eliminate many of the incentives for gerrymandering. Under a proportional system, if a party gets 40% of the vote, it gets roughly 40% of the seats, regardless of how districts are drawn. States like Maine and Nebraska are experimenting with ranked-choice voting and other reforms, but a full shift to proportional representation would require major legislative changes.

The trajectory of gerrymandering ultimately depends on public awareness and political engagement. As more citizens understand the mechanics of district manipulation, the pressure for reform grows. Organizations like Common Cause, the League of Women Voters, and the Brennan Center for Justice continue to litigate, lobby, and educate. In the 2024 election cycle, several state legislatures are considering independent redistricting bills, and at least a dozen states have active court cases challenging existing maps.

Conclusion

Gerrymandering is not a relic of the 19th century—it is a live, corrosive force in modern democracy. It distorts representation, silences minority voices, erodes trust, and empowers extremists. While the practice is deeply entrenched, the tools to combat it are growing stronger: independent commissions, state court action, algorithmic mapping, and a motivated public. The challenge lies in transforming awareness into reform. Without systemic change, American elections will continue to be rigged by the very people who are supposed to serve the voters. The next decade will be critical in determining whether redistricting becomes a tool for democracy—or a machine that crushes it.
