Navigating the “Political Thicket”: A Conversation with Professor Ruth Greenwood on Gerrymandering and the Future of the Voting Rights Act

Rodger Citron Nov 5, 2025

On a recent episode of the Touro Law Review podcast, I was pleased to host a timely and incisive discussion with Ruth Greenwood, Assistant Clinical Professor and Director of the Election Law Clinic at Harvard Law School.
In this episode, Professor Greenwood and I discussed the legal and political landscape of electoral districting. More specifically, our discussion focused on the Supreme Court’s hands-off approach to partisan gerrymandering and the pending constitutional challenge to the Voting Rights Act (VRA).
For a comprehensive analysis of these critical issues, I invite you to listen to our full discussion, available here. With the assistance of Artificial Intelligence (AI), I provide a summary below of the key points of our conversation.
Gerrymandering Defined
Professor Greenwood began our conversation by defining gerrymandering, tracing the concept back to its origins with Massachusetts Governor Elbridge Gerry in 1812. While the term originally described the drawing of bizarrely shaped districts (a “salamander”), its modern meaning is the drawing of electoral lines to seek advantage for a specific group—be it a political party, a racial group, or a set of incumbents.
Professor Greenwood provided a thumbnail history of gerrymandering, from malapportionment through the Supreme Court’s “one person, one vote” jurisprudence in the 1960s up to partisan gerrymandering today. As she elaborated:
  1. Malapportionment, the original method of gerrymandering, involved creating districts of vastly unequal populations, diluting the power of urban voters.
  2. In the 1960s, the Supreme Court entered the “political thicket,” applying the Equal Protection Clause to mandate districts of equal population according to the principle of “one person, one vote.”
  3. With populations equalized, parties seeking an advantage turned to sophisticated methods of “packing” and “cracking” voters based on their known political affiliations. This is the form of (political) gerrymandering pursued today.
Professor Greenwood gave the following example of modern gerrymandering: The 2012 Wisconsin election, in which Democrats won 52 percent of the statewide vote but secured only 37 percent of the state assembly seats—a “wrong winner outcome” that strikes many as fundamentally anti-democratic.
The Federal Courts Step Back: Rucho v. Common Cause (2019)
Professor Greenwood then discussed the federal judiciary’s current stance on partisan gerrymandering. She detailed the Supreme Court’s 2019 landmark decision in Rucho v. Common Cause. (As Professor Greenwood noted in the podcast, she litigated Rucho from the trial level to the Supreme Court.) In a 5-4 opinion written by Chief Justice John Roberts, the Court held that claims of partisan gerrymandering present a non-justiciable political question. While conceding that “excessive” extreme partisan was “incompatible with democratic principles,” the majority nevertheless held that federal courts lacked a “manageable standard” to determine when lawful political considerations crossed the line into unconstitutional partisanship. The Court concluded that political gerrymandering must be addressed primarily by the legislative branches, not the federal courts.
Justice Elena Kagan dissented. She argued that manageable standards do exist and that the Court was abdicating its constitutional duty by holding that political gerrymandering claims were not justiciable in federal court. As Professor Greenwood noted, Kagan’s dissent emphasized that voters should choose their politicians—not the other way around.
Now Pending at the Supreme Court: Callais v. Landry
In addition to political gerrymandering, Professor Greenwood and I discussed litigation now pending at the Supreme Court involving claims under Section 2 of the VRA.
Initially Professor Greenwood provided an overview of the VRA, which evolved from protecting the right to vote (that is, combatting disenfranchisement) to protecting the value of the vote (that is, combatting vote dilution). The 1982 amendments to the VRA established a “results test,” allowing plaintiffs to challenge districting maps that have a disparate impact on minority voters regardless of the map-drawers’ intent. This results test was affirmed by the Supreme Court in 1986 in Thornburg v. Gingles.
The “results test” doctrine is now at the center of a case now pending at the Supreme Court, Callais v. Landry. Professor Greenwood, whose clinic is involved in the case, set out the history of the case: Following the 2020 census, plaintiffs brought a Section 2 lawsuit (Robinson v. Landry) arguing that Louisiana, which has a one-third Black population, must draw two, rather than one, majority-Black congressional districts.
Subsequently, after the Supreme Court applied Gingles in an Alabama case involving a challenge to the state’s redistricting map, Allen v. Milligan (2023), the Louisiana legislature acted to comply with the VRA by drawing a new map with a second majority-Black district.
This prompted a group of white voters, the plaintiffs in Callais, to sue. They argued that this new map was an unconstitutional racial gerrymander under the 14th Amendment. Citing the Supreme Court’s decision in Shaw v. Reno (1993) and other authorities, the plaintiffs asserted that race improperly “predominated” in the Louisiana’s legislature’s decision when creating the second majority-Black district.
According to Professor Greenwood, Callais presents the following question: Does complying with Section 2 of the VRA inherently require an unconstitutional racial gerrymander? The Court’s decision could determine the future viability of the VRA.
The Path Forward: Advocacy Inside and Outside the Courts
Professor Greenwood concluded that in this challenging legal environment, advocates for fair political representation must pursue a multi-pronged strategy. While litigation remains a crucial tool for creating a “record,” Rucho demonstrates the limitations of a court-centric approach.
The most durable solution, she argues, is outside the judiciary. In states like Michigan, Professor Greenwood noted, activists successfully used a ballot initiative to create an independent redistricting commission, thereby taking the map-drawing power away from partisan legislators entirely. This combination of legal advocacy and grassroots organizing, Professor Greenwood said, is essential to ensuring that American democracy lives up to its foundational principles.

Could President Trump Be Punished for Killing Suspected Drug Traffickers on the High Seas? University of Chicago law professor emeritus Albert W. Alschuler examines whether President Donald Trump could face legal consequences—either domestically or internationally—for ordering the U.S. military to kill at least 64 suspected drug traffickers on the high seas without trial, purportedly as part of a broader anti-cartel strategy. Professor Alschuler argues that these killings constitute unlawful acts that violate U.S. and international law, likening them to extrajudicial executions, and concludes that while prosecution is theoretically possible, political and legal obstacles, including questionable legal justifications and potential presidential immunity, make accountability unlikely....

Botched Execution in Alabama Reveals Nitrogen Hypoxia’s True Colors, and It Is Not a Pretty Picture Amherst professor Austin Sarat criticizes the use of nitrogen hypoxia as a method of execution, particularly in Alabama, where it has resulted in prolonged, painful deaths that contradict claims of a humane alternative to previous execution methods. Professor Sarat argues that nitrogen hypoxia, like earlier methods, has failed to provide a foolproof or ethical solution and calls for the abolition of capital punishment altogether, emphasizing the psychological and physical torture it inflicts and questioning what such practices say about the values of American society....

Professor Dorf argues that Johnson’s actions appear to be a politically motivated and constitutionally baseless effort to block Grijalva from voting—potentially on the Epstein files discharge petition—and reflects a broader disregard for democratic norms and the rule of law....
