🚨Today is publication day for my book, "Aligning Election Law"! The book argues that promoting alignment between governmental outputs and popular preferences should be an overarching goal of election law. You can buy the book at the link below. global.oup.com/academic/prod…

In Wisconsin, "[t]he simulations ... suggest [a 6-2 Republican advantage] is exactly what one should expect from a party-blind map." This is why we're challenging the plan on ANTI-COMPETITIVE grounds. The simulations strongly support that distinct claim. nytimes.com/interactive/2026…

I just posted this book chapter on the value of alignment -- the government doing what the people want -- in comparative perspective. It's part of a forthcoming volume edited by Shreya Atrey and Ros Dixon. papers.ssrn.com/sol3/papers.… Here's the abstract:

Beyond elections, the courts have intervened to fix distortions of the legislative process and to address issues including secession, corruption, broadcasting, and treatymaking.

In sum, this rich body of case law establishes that alignment operating as a constitutional value isn't some fanciful academic notion. Rather, it's a tangible legal reality in constitutional systems around the globe.

New paper by @ruthgreenwood and me: "The Death and Rebirth of Vote Dilution," forthcoming in the Supreme Court Review. We show how the Court tried to kill the concept of racial vote dilution in Callais -- and why this idea will never die. papers.ssrn.com/sol3/papers.…

Nor does Callais impede race-neutral strategies that nevertheless stop much racial vote dilution. Two of these approaches are familiar: prohibitions of partisan gerrymandering and systems of proportional representation.

We further propose a cause of action for non-racial vote dilution. This novel claim would work just like its racial analogue-except it would revolve entirely around a non-racial cleavage.

We filed our reply brief on Friday in our anti-competitive gerrymandering challenge against Wisconsin's congressional districts. The issue (for now) is only whether our claim is cognizable under Wisconsin's constitution. Oral argument is on Sept. 16. hlselectionlaw.org/s/2026082…

New article: @aaronrkaufman, @Chris_T_Kenny, and I just posted "Intra-Partisan Gerrymandering," forthcoming in @michlawreview. The piece looks at one faction within a party using redistricting to disadvantage another faction within the same party. papers.ssrn.com/sol3/papers.…

Its representational harms are analogous to those inflicted by partisan gerrymandering, and it can be regulated through a similar doctrinal framework. Finally, we offer an empirical proof of concept using a recent state senate redistricting as a case study.

It’s feasible to identify intra-party factions, measure disparities in their treatment, and assess plans’ fairness with quantitative metrics and computer-generated maps.
