Background

The State Democracy Research Initiative is a non-partisan research centre housed at the University of Wisconsin Law School that tracks state-level election law, redistricting, and voting rights litigation. Its voter-roll lawsuit tracker, updated in April 2026, records Department of Justice suits against 30 states plus the District of Columbia — a figure that has become the standard citation across media coverage and litigation filings documenting the scale of the Trump administration's voter-registration campaign.

Founded within the Law School's nationally recognised election law programme, the Initiative produces policy analyses, court-filing trackers, and comparative legislative studies used by journalists, policymakers, and litigants on both sides of voting-rights disputes. Its work is cited in federal court briefings and Congressional testimony.

In the 2026 cycle the Initiative's documentation of the 30-state scope of DOJ litigation has been particularly significant: it provides independent corroboration of a campaign that the administration has described in more limited terms, and it creates a public record that advocacy organisations including Democracy Forward have used to frame their FOIA and litigation strategy against the DOJ.
