Post-Shelby voter-roll purges, by the numbers

The Brennan Center for Justice's two-cycle audit of voter-roll removals ('Voter Purges' [2018] and the 2020 update) compared purge rates in jurisdictions previously covered by Voting Rights Act Section 5 preclearance to non-covered jurisdictions, before and after Shelby County v. Holder (2013).

Between 2014 and 2016, the median purge rate in previously covered jurisdictions was 40 percent higher than the median in non-covered jurisdictions — a gap that did not exist before Shelby. Across the two cycles between 2014 and 2018, the Brennan Center estimated 17 million voters were removed from the rolls; of those, approximately 33 million Americans were registered in previously covered jurisdictions, and they accounted for a disproportionate share of the removals.

Carol Anderson, in ``One Person, No Vote``, threads the post-Shelby record into the longer voter-suppression history: poll taxes, literacy tests, registration purges, voter-ID laws, polling-place closures, and signature-match rejection are mechanisms in the same operational family. The mechanism changes; the outcome — disproportionate disenfranchisement — does not.

Voter-roll list maintenance is the regulatory term for the procedural framework by which state and local election officials remove voters from the registration rolls. The principal federal statutory framework is the National Voter Registration Act of 1993 (NVRA). The NVRA permits removal of voters for specified reasons and prohibits removal for any other reason. The Supreme Court's 2018 decision in Husted v. A. Philip Randolph Institute upheld Ohio's 'supplemental process' for voter-roll list maintenance against an NVRA challenge and substantially narrowed the NVRA's constraint on inactivity-based purge regimes.

The Brennan Center for Justice's tracking has documented approximately 19 million voter-roll removals between 2014 and 2020. The racial-demographic analysis of the purged registrations has documented disproportionate representation of Black, Latino, and young voters. The Georgia 'use it or lose it' purge framework, implemented under Secretary of State Brian Kemp and litigated in the Fair Fight Action v. Raffensperger case, became a national reference case for the post-Husted period. Approximately 534,000 Georgia voter registrations were canceled in a single 2017 maintenance cycle.

The post-2020 voter-roll-purge activity has expanded substantially in the post-2020-election period. Several states have adopted additional list-maintenance frameworks, expanded existing frameworks, or modified their interpretations of the NVRA's procedural requirements. Texas, Florida, Ohio, Wisconsin, North Carolina, and Arizona have been the principal states with documented expansions of voter-roll-purge activity. The litigation challenging these expansions has been active in federal and state courts across the affected jurisdictions; the outcomes have been mixed.

The Election Registration Information Center (ERIC), an interstate-information-sharing consortium that supports state list-maintenance through cross-jurisdictional duplicate-registration identification, has been the subject of substantial recent political controversy. Several states have withdrawn from ERIC participation since 2022, substantially reducing the consortium's geographic coverage. The withdrawals have been driven principally by political concerns about the consortium's relationship to broader voter-registration policy debates rather than by documented operational problems with the consortium's data-sharing framework.

The reform proposals at the federal level include the John Lewis Voting Rights Advancement Act, which would establish a new Section 4(b) preclearance coverage formula and would substantially constrain post-Shelby list-maintenance expansions in formerly-covered jurisdictions. The Act has been introduced in successive Congresses since 2019 but has not passed. The Freedom to Vote Act, which would establish additional federal procedural protections for voter-registration practices, has been introduced in successive Congresses and has not passed. The platform's framing treats voter-roll list maintenance as one of the principal contemporary operational mechanisms by which voter access is shaped at the procedural level, and as one of the principal post-Shelby substantive areas of federal voting-rights litigation.

The contemporary state-level voter-roll-list-maintenance litigation activity continues across multiple jurisdictions. The Texas voter-roll-purge litigation, brought by the Brennan Center for Justice and the parallel voting-rights organizations, addresses the state's post-2020 list-maintenance practices and the citizenship-verification framework that the state has incorporated into its list-maintenance practice. The Florida voter-roll-purge litigation addresses the state's post-2020 list-maintenance practices and the broader changes in the state's voting-rights framework. The Ohio, Wisconsin, North Carolina, and Arizona voter-roll-purge litigation addresses parallel state-level developments. The cumulative litigation activity reflects the substantial expansion of voter-roll-purge activity in the post-2020-election period.

The federal-level reform proposals addressing voter-roll-purge practices include the John Lewis Voting Rights Advancement Act (which would establish a new Section 4(b) preclearance coverage formula constraining post-Shelby list-maintenance expansions in formerly-covered jurisdictions) and the Freedom to Vote Act (which would establish federal minimum standards for state-level list-maintenance procedures). Both proposals have been introduced in successive Congresses since 2019 and have not passed. The platform's pathways pages cover the principal Election Protection, Brennan Center for Justice, Lawyers' Committee for Civil Rights Under Law, and ACLU intake routes for voting-rights complaints.

The empirical research on the operational effects of post-Husted purge frameworks continues to develop. The cumulative scholarship documents that inactivity-based purge regimes produce disproportionate removal rates for younger voters, lower-income voters, and voters in residentially-mobile demographic categories. The Stanford-MIT Election Lab's tracking of post-2020 list-maintenance activity has produced substantial documentation of state-by-state variation in operational practice. The Election Assistance Commission's annual reports on the National Voter Registration Act implementation document additional dimensions of the framework's operational practice across the affected jurisdictions.
