After a Supreme Court ruling, expect even more gerrymandering

A landmark Supreme Court decision this week has fundamentally altered the legal landscape for challenging partisan gerrymandering, effectively giving state legislatures a much freer hand in drawing congressional districts to their political advantage. The ruling immediately sent shockwaves through the political system, with North Carolina’s legislature swiftly passing a new, aggressive congressional map that analysts say could lock in a supermajority for one party for the remainder of the decade.

The 6-3 decision sharply raises the burden of proof for plaintiffs arguing that new electoral maps are racially discriminatory, a key legal avenue used to fight partisan gerrymandering since the Court closed other doors in 2019. For voters, businesses, and investors, the ruling signals a future of heightened political polarization and increased gridlock, with profound implications for economic policy and regulatory stability.

The Landmark Ruling: South Carolina v. NAACP

The pivotal case, South Carolina v. NAACP, centered on the state's new congressional map, which challengers argued was an unconstitutional partisan gerrymander that was achieved through discriminatory racial sorting. The Court’s conservative majority established a stringent new standard for such cases.

• The Core Issue: The Court was asked to determine the standard for proving that race, rather than partisan affiliation, was the primary motivation behind the drawing of a specific district. This distinction is critical because the Court has previously ruled that federal courts can adjudicate claims of racial gerrymandering but not purely partisan gerrymandering.

• The Majority Opinion: Authored by Justice Samuel Alito, the majority found that challengers must now demonstrate that race was the "predominant" and "but-for" cause of a district's lines. The opinion states that when a map's lines can be explained by partisan motivations, courts must presume the legislature acted with political, not racial, intent. This creates a high wall for plaintiffs to climb, as partisan affiliation and race are often highly correlated in voting patterns.

• The Dissenting View: Justice Elena Kagan, in a forceful dissent, argued that the majority’s new standard "guts" a core protection of the Voting Rights Act. She wrote that the ruling provides a "how-to guide" for state legislatures to enact racially discriminatory maps and insulate them from legal review simply by claiming partisan goals.

Immediate Political Fallout: North Carolina's New Map

Within 48 hours of the Supreme Court's decision, the Republican-led North Carolina General Assembly, feeling legally emboldened, convened a special session to pass a new congressional map. The previous map, which was implemented by state courts, had produced a 7-7 split in the state's 14-member delegation.

• The Partisan Shift: The new map, according to analyses from the Brennan Center for Justice and the Princeton Gerrymandering Project, is heavily favored to produce a 10-4 or even 11-3 Republican majority in the U.S. House delegation.

• The Method: The map achieves this advantage through aggressive "cracking" and "packing." It "cracks" urban Democratic voters in cities like Charlotte and Raleigh across multiple conservative-leaning suburban and rural districts, diluting their voting power. It also "packs" remaining Democratic voters into a few overwhelmingly Democratic districts.

• The Justification: Legislative leaders in Raleigh issued a statement claiming the map was drawn in adherence to "traditional, race-neutral redistricting principles" and that the Supreme Court's recent ruling affirmed their authority to prioritize political considerations.

Background: The Closing of the Federal Courthouse Doors

This week’s ruling is the culmination of a decade-long trend of the Supreme Court stepping back from policing partisan map-drawing.

• The 2019 Precedent: In Rucho v. Common Cause, the Court declared that partisan gerrymandering presents a "political question" beyond the jurisdiction of federal courts. This landmark decision effectively ended all purely partisan challenges to district maps in the federal system.

• The Previous Strategy: Following Rucho, civil rights groups and Democratic-aligned organizations shifted their legal strategy. They began challenging partisan-motivated maps under the Voting Rights Act, arguing that extreme partisan gerrymanders often rely on racial data and have a disproportionately negative "disparate impact" on minority voters.

• The New Reality: The South Carolina v. NAACP decision severely curtails this workaround. By requiring plaintiffs to prove race was the predominant motive and allowing legislatures to use partisanship as a defense, the Court has made these VRA-based challenges exponentially more difficult to win.

The Economic and Financial Implications

While redistricting is a political process, its outcomes have direct and significant economic consequences. Increased gerrymandering leads to more "safe" seats, which in turn reduces the incentive for political compromise.

• Policy Gridlock: With fewer competitive districts, elected officials face more pressure from their party's base than from the general electorate. This dynamic fuels legislative paralysis on critical economic issues, including federal budgets, debt ceiling negotiations, tax reform, and long-term infrastructure investment.

• Regulatory Whiplash: Extreme partisan control of the House, locked in by gerrymandering, can lead to dramatic swings in regulatory policy from one administration to the next. This uncertainty in areas like environmental standards, financial regulation, and labor law makes it difficult for businesses to engage in long-term capital planning and investment.

• Distorted Fiscal Priorities: Representatives in non-competitive districts have a greater incentive to secure targeted federal spending for their specific constituents (earmarks or "pork") rather than focusing on policies that promote broad-based national economic growth.

What Comes Next

The battle over fair representation is now set to shift almost entirely away from the federal judiciary.

• State-Level Fights: The primary venue for challenging gerrymandered maps will now be state courts. Litigants will argue that maps violate provisions in state constitutions, many of which have "free and fair election" clauses that can be interpreted more broadly than the U.S. Constitution.

• Citizen-Led Initiatives: Expect a surge in ballot initiatives in states that allow them. Activist groups will likely push for the creation of independent, non-partisan redistricting commissions, which have been adopted in states like Michigan, Colorado, and California to take map-drawing power away from politicians.

• Congressional Action: Calls will grow louder for Congress to pass federal legislation setting national standards for redistricting, such as the For the People Act or the John Lewis Voting Rights Advancement Act. However, such legislation faces insurmountable hurdles in a deeply divided Senate.

• The 2024 Election and Beyond: The new, more aggressively gerrymandered maps in key states like North Carolina, South Carolina, and others will be in place for the 2024 elections. Their impact will be immediate, heavily influencing the balance of power in the House of Representatives and shaping the contours of American politics and economic policy for the rest of the decade.
