The Cato Institute is the pre-eminent libertarian policy organisation in the United States, founded in 1977 in San Francisco by Charles Koch, Murray Rothbard and Edward Crane and now headquartered in Washington DC. It is formally non-partisan, backing free markets and minimal government on economic questions while supporting civil liberties, immigration reform and criminal justice reform in ways that sometimes align it with Democrats and sometimes with Republicans.
Cato weighed in on the DOJ's national voter-data programme ahead of the 9th Circuit's first appellate hearing on the issue, arguing on 19 May 2026 that the programme lacks statutory authority. That statutory-gap reasoning gained its first appellate endorsement on 24 June 2026, when a Sixth Circuit panel ruled 2-1 in United States v. Benson that the Civil Rights Act of 1960 could not authorise the DOJ's demand for Michigan's unredacted voter rolls, a ruling that also binds Ohio, Kentucky and Tennessee.
Cato's involvement reflects the think tank's decade-long interest in election law and federalism; it has filed amicus briefs in major voting-rights cases and its scholars have testified before Congress on voter-ID, redistricting and census methodology. Its consistent position, that federal election law should not be used to compel states to hand over voter data beyond what statutes explicitly authorise, has now been adopted in eight district-court dismissals and the Sixth Circuit's first appellate ruling.
