Meet the reformer: Sam Wang, a professor of fair redistricting math

Sam Wang, Princeton Gerrymandering Project

Sam Wang is the director of the Princeton Gerrymandering Project.

Princeton Gerrymandering Project

Sam Wang is a professor of neuroscience at Princeton, where he's been on the faculty 14 years and focuses on how the brain processes sensory, cognitive and emotional information. But he's also part of the university's Program in Law and Public Affairs. He created the Princeton Election Consortium in 2008 to come up with statistical models for predicting presidential and Senate results based on polling. And after the last nationwide redistricting, in 2012, he created the Princeton Gerrymandering Project. Today he and his seven-member team run a website that permits voters to use mathematical models to decide if where they live is in an unfairly skewed legislative or congressional district. His answers have been edited for clarity and length.

What's the tweet-length description of your organization?

Combining data, tech and law to help citizens make district lines fairer and eliminate bugs from democracy.


Describe your very first civic engagement.

In 1978, when I was in sixth grade in California, I became very interested in two ballot propositions that would affect school funding. I loved school so these were important to me. The one that would have increased school funding, Proposition 8, failed. The other was Proposition 13, the first of many tax-cutting initiatives passed across the nation. After that, school funding was cut dramatically. So my side lost. But in politics you should never give up.

What was your biggest professional triumph?

In neuroscience it's a tie. First, figuring out how a brain structure, the cerebellum, which is mainly known for processing sensory information to help us move smoothly, could also guide higher function and when it goes off track lead to autism. Also, seeing the success of dozens of great students and scholars who have gone on to do all kinds of amazing things.

In redistricting it's another tie. First, seeing my team shape redistricting fairness in New Jersey by stopping a ballot initiative that would have biased districting, possibly helping with the wording of a fairer initiative and then getting an actual law passed to mandate transparency in precinct voting data so citizens can see what's being done to their district lines. Second, seeing Chief Justice John Roberts quote my words that there are good mathematical tests for identifying partisan gerrymandering

And your most disappointing setback?

Chief Justice Roberts again. He is not a math guy and he was not taking our side. Despite having no quarrel with our math, he wrote the majority opinion last year that wussed out and turfed the question of partisan gerrymandering back to the individual states to deal with. It was in my view an abdication of the Supreme Court's duty to stop a clear constitutional offense in the face of airtight mathematical and geometric approaches. The good news is that all our technical approaches can be used in the states — and we are doing that in North Carolina, Virginia, Michigan and half a dozen others. So we get to stay in business for a while.

How does your identity influence the way you go about your work?

As a former physics guy from a relatively privileged demographic, I started thinking about districting fairness in simple terms for which we could establish a national standard: fairness between the parties and numerical tests for racial bias. After encountering the needs of real communities, I've now learned that the richness of communities across the nation deserve consideration. We're working on ways to present that effectively across many states. This probably fits well with my work as a biologist, part of which involves attending to a lot of details.

What's the best advice you've ever been given?

It's better to ask for forgiveness than permission.

Create a new flavor for Ben & Jerry's.

Honey-dipped locust. (An homage to the cricket I ate live on CNN in 2016 to settle a bet. My statistical analysis of the polls had prompted me to wager I would "eat a bug" if Donald Trump won more than 240 electoral votes.)

What is your favorite TV show or movie about politics?

"Mean Girls."

What's the last thing you do on your phone at night?

I don't understand what the word "last" is doing in that sentence. That implies stopping, right?

What is your deepest, darkest secret?

I once made a pilgrimage to Carhenge.

How 9/11’s Memory Continues to Shape American Citizenship

Twenty‑five years after September 11th, the burden of that day continues to affect us in ways that are difficult to express. It was a moment of profound loss, but also one that revealed both the vulnerability and resilience of our national fabric. The memories remain vivid for many of us: where we were, what we felt, and how the world appeared to change in an instant. Even now, a quarter century later, the impact of that morning continues to shape how we understand our country, our responsibilities, and our relationships with one another.

To help us all reflect on that day, I invited four contributors to the Fulcrum to share reflections not to revisit the tragedy, but to commemorate the ways it has persisted in our consciousness twenty-five years later.

Ballot Security and Voter Access Are Not Opposites: What the USPS Ballot Rule Gets Right

I came to the United States from India in 1982. In Indian elections, I watched officials check voter identity and mark a voter’s finger with indelible ink. Party representatives observed the process. The system was imperfect, as every large democracy is, but it sent a simple message: casting one vote is a serious civic act, and the process should make that clear.

When I later became an American citizen and cast my first ballot, the experience felt very different. A poll worker found my name on a list and handed me a ballot. In my precinct, there was no photo identification check. I was surprised—not because I expected voting to be difficult, but because I expected a system as consequential as an election to have clear, visible safeguards.

What America Can Do About Its Uncontested Elections

Politics nerds have many ideas about how to strengthen American democracy; however, few directly address silent elections. For example, ranked-choice voting does nothing to encourage more candidates to run if there are not enough. Term limits increase turnover, but even newcomers can frequently run uncontested in general elections if they have won competitive primaries.

Fortunately, the cause isn’t hopeless. For one, tightening campaign finance laws would put potential challengers on more even footing with corporate-backed politicians, encouraging more candidates to run. Independent redistricting would also help. The Cook Political Report, a poll aggregator, considers only 69 of America’s 435 House districts competitive. Fair redistricting means more competitive districts and therefore more contested elections.

Non-Popular Vote Presidents: Conservatives’ Pathways for Abandoning Fiscal Responsibility

In political science and macroeconomic analysis, conservative administrations that win governance through the Electoral College without securing the national popular vote (historically exemplified by administrations like George W. Bush in 2000 and Donald Trump in 2016) navigate specific structural, ideological, and strategic pathways that often lead to the abandonment of traditional fiscal restraint.
