Briefs: Gerrymandering – When the Map Becomes the Election

Gerrymandering sounds like a technical issue, but it goes to the heart of representative government. Every ten years, after the census, states redraw congressional districts so that representation reflects population change. That process is necessary. Populations move, cities grow, suburbs expand, and rural areas shrink.

The problem begins when district lines are drawn less to represent voters than to protect political power. A fair map allows voters to choose their representatives. A gerrymandered map allows representatives — or their parties — to choose their voters.

The Strange History of the Word

The term gerrymander dates to 1812, when Massachusetts Governor Elbridge Gerry signed a redistricting plan that benefited his Democratic-Republican Party. One oddly shaped district was said to resemble a salamander. The Boston Gazette called it a “Gerry-mander,” and the name stuck.

The word began as political satire. The practice became a durable feature of American politics.

Gerrymandering is not new. What is new is the precision. Modern software, voter files, demographic data, and partisan modeling allow mapmakers to draw lines with remarkable accuracy. A neighborhood here, a suburb there, a city split down the middle — small changes can produce large political effects.

Not Every Lopsided District Is Gerrymandered

Some districts will naturally lean Democratic. Others will naturally lean Republican. That is not necessarily abuse.

Geography, culture, economics, education, religion, race, age, and urban-rural differences all shape voting patterns. Downtown Denver, rural Alabama, northern Virginia suburbs, west Texas, and parts of Louisiana are not politically identical places.

The real problem is not that some districts are predictable. The problem is when mapmakers deliberately manipulate the districts in between — the ones that could be competitive — by packing one group’s voters into a small number of districts or cracking them across many districts so they cannot influence outcomes.

That is where the map becomes part of the election itself.

Packing, Cracking, and Power

Two tactics define most gerrymanders:

• Packing concentrates voters from one party or group into a small number of districts. They may win those districts overwhelmingly, but their excess votes are wasted.

• Cracking splits voters from one party or group across several districts so they are never numerous enough to win.

Both tactics can be used for partisan advantage. They can also weaken racial or ethnic minority representation, especially where race, geography, and party preference overlap.

That overlap is the hard part. A mapmaker may say, “We were targeting Democrats,” while the practical effect may be to weaken Black, Latino, Native American, Asian American, or other minority voters. Conversely, a state may say it is protecting minority representation, while critics may argue that the state is sorting voters too explicitly by race.

That tension sits at the center of the current debate.

Redistricting can change political outcomes without changing a single voter. By packing some voters into a few districts and cracking others across many districts, mapmakers can turn the same statewide vote into a very different balance of representation.

The Voting Rights Act and the Race Problem

The Voting Rights Act of 1965 was passed because formal voting rights were not enough. A person could have the legal right to vote yet live under election rules that make meaningful representation nearly impossible.

Section 2 of the Voting Rights Act prohibits voting practices that deny or abridge voting rights based on race, color, or membership in certain protected language-minority groups. It is not limited to Black voters. It can also apply to Latino, Native American, Asian American, Alaska Native, and other protected minority communities when the legal standards are met.

In redistricting, the core concern is racial vote dilution. That does not mean someone is prevented from casting a ballot. It means district lines are drawn so that a minority group’s votes are packed or cracked, weakening its ability to elect candidates of its choice.

But there is a competing constitutional principle: government generally may not sort citizens by race unless it has an extremely strong justification. So the law pulls in two directions:

• The Voting Rights Act says: Do not draw maps that dilute minority voting power.

• The Constitution says: Do not assign voters to districts mainly based on race.

That is the collision.

Louisiana: The Hard Case

Louisiana shows why this issue is so difficult. The state has six congressional districts. Black residents make up roughly one-third of Louisiana’s population, but the earlier congressional map had only one majority-Black district.

Voting-rights plaintiffs argued that this diluted Black voting power and that a fair map should include a second district where Black voters had a realistic opportunity to elect their preferred candidate. Louisiana then adopted a map with a second majority-Black district.

But that map was challenged by voters who argued that the state had used race too heavily when drawing the lines. The Supreme Court agreed. In Louisiana v. Callais, the Court invalidated the map and sharply limited the use of race-conscious districting under Section 2 of the Voting Rights Act.

Supporters of the ruling described it as a necessary enforcement of a colorblind constitutional principle. Government, in this view, should not divide voters into racial blocs, even for remedial purposes.

Critics described the ruling as a major weakening of the Voting Rights Act. In their view, ignoring race in places where race, geography, party, and political power are deeply intertwined may preserve the effects of past discrimination.

Both concerns are serious. That is why Louisiana cannot be reduced to a slogan. It is not simply about “fair maps.” It is about two anti-discrimination principles colliding with each other.

Recent Redistricting Flashpoints

The Louisiana case is part of a broader national fight over congressional maps. The details differ by state, but the larger pattern is clear: redistricting has become a national arms race.

Texas

Texas became a central example of mid-decade redistricting. Republican leaders backed a new congressional map designed to increase the number of Republican-leaning seats.

Texas officials have defended the effort as partisan mapmaking rather than racial discrimination. Opponents argue that, in a state where race, ethnicity, geography, and party preference overlap, aggressive partisan line-drawing can also dilute minority voting power.

California

California responded from the other direction. The state moved toward a new congressional map intended to benefit Democrats, which supporters framed as a response to Republican redistricting efforts elsewhere.

That makes California a useful example of the redistricting arms race: one party redraws in one state, and the other party responds in another.

Virginia

Virginia has also entered the fight. Voters approved a temporary redistricting measure backed by Democrats, but the process faced legal challenge.

Virginia illustrates a different problem: even voter-approved redistricting changes can give rise to procedural and constitutional disputes.

Louisiana

Louisiana is different from Texas, California, and Virginia because the dispute is not only partisan. It is centered on race, the Voting Rights Act, and the Equal Protection Clause.

The state was first pushed toward a second majority-Black district because of Section 2 concerns. Then the Supreme Court rejected the resulting map as unconstitutional racial gerrymandering.

Together, these states show why redistricting has become one of the most consequential fights in American politics. Texas and California show the partisan arms race. Virginia shows the procedural and institutional instability. Louisiana shows the collision between minority-vote protection and constitutional limits on race-conscious government action.

Why the Courts Have Not Solved It

The courts have only partly addressed the problem. In Rucho v. Common Cause, the Supreme Court held that partisan gerrymandering claims generally present political questions beyond the reach of federal courts. In plain English, federal courts usually will not strike down a map simply because it gives one party too much advantage.

Race is treated differently. Courts can still review racial gerrymandering and racial vote-dilution claims. But the Louisiana decision makes that line harder to draw.

States may not dilute minority voting power. But they also may not rely too heavily on race to fix that problem.

That is why redistricting is not easily solved by saying, “Draw fair maps.” A fair map has to balance several principles at once:

• Equal population

• Contiguous districts

• Reasonable compactness

• Respect for cities, counties, parishes, towns, and communities of interest

• Compliance with the Voting Rights Act

• Protection against extreme partisan entrenchment

• Transparency in how the final map was chosen

No single rule solves the problem. Compactness helps, but a compact district can still split a real community. Competitiveness helps, but not every district should be artificially competitive. Race cannot be ignored, but race should not become the sole organizing principle. Party data may reveal manipulation, but party preference is also part of democratic life.

Why the Problem Is Getting Worse

For most of modern American history, redistricting was mainly a once-every-ten-years process. That norm is weakening.

The National Conference of State Legislatures reported that in 2025, states were undertaking mid-decade redistricting at rates “not seen since the 1800s.” That is a warning sign.

Once one state redraws its map for partisan gain, the other side feels pressure to retaliate somewhere else. Texas prompts California. California prompts more Republican states. Virginia enters the fight. Louisiana opens new legal questions.

The mapmaking process becomes a national arms race. Both parties can justify their own maps as defensive. Both can accuse the other side of hypocrisy. But the public interest gets lost.

The principle should not depend on which party benefits today.

Proposals Already in Congress

Several members of Congress have proposed reforms.

The Redistricting Reform Act of 2025, introduced by Sen. Alex Padilla and Rep. Zoe Lofgren, would prohibit mid-decade congressional redistricting nationwide and require states to establish independent redistricting commissions.

The Fair Representation Act, reintroduced by Rep. Don Beyer and Rep. Jamie Raskin, would go further. It would use ranked-choice voting and multi-member districts for U.S. House elections, with districts drawn under nonpartisan redistricting rules.

Rep. Steve Cohen has introduced the John Tanner and Jim Cooper Fairness and Independence in Redistricting Act, which would require states to use independent redistricting commissions and remove politics more directly from congressional line-drawing.

Rep. Kevin Kiley has proposed legislation to prohibit mid-decade redistricting nationwide. His proposal is narrower than the commission-based bills, but it addresses the same escalation problem.

These proposals differ, but they share an important premise: the people who benefit from district lines should not have unchecked power to draw them.

A Practical Path Forward

No reform will make redistricting perfectly neutral. Communities are not perfect squares. Political geography is real. Racial geography is real. Competitive districts cannot be manufactured everywhere without creating distortions of their own.

But a better system is possible. The most practical reform would include five elements:

1. Keep the ten-year census cycle.
   That provides stability and prevents constant election-map warfare.

2. Ban mid-decade redistricting except when a court finds the existing map illegal.
   This would reduce the arms race.

3. Use independent or genuinely bipartisan commissions.
   Legislators should not have unchecked power to choose their own voters.

4. Require public map scoring.
   Every proposed map should be evaluated for equal population, compactness, city and county splits, community integrity, racial vote dilution, partisan bias, and competitiveness.

5. Allow prompt judicial review under clear rules.
   Courts should not become permanent mapmakers, but they should be able to enforce transparent standards.

The goal is not to make every district competitive. Some communities really are politically lopsided.

The goal is more modest and more important:

Do not manufacture political outcomes that voters themselves did not create.

Gerrymandering will never disappear entirely. Political power always creates temptation. But a representative democracy need not accept temptation as destiny.

A fairer system begins with a simple principle:

Voters should choose their representatives. Representatives should not choose their voters.
