Federal Judge Takes Over California Ballot Dispute as State Challenges 20,000-Name List

Key points

• Attorney General Rob Bonta called the federal lawsuit 'absurd' and urged a judge to block an order forcing California to segregate 20,000 ballots.
• Federal prosecutors charged 28 green card holders with voting or registering illegally, but acknowledged the list of 20,000 names may include citizens.
• Los Angeles County officials found that 38.9% of a sample of flagged voters were born in the U.S., and 71.2% had never voted.
• The case was transferred to Judge David O. Carter, who previously ruled against the DOJ’s attempts to access unredacted voter rolls.
• The Justice Department claims a separate batch of 17,000 additional potential noncitizen voters exists, though state officials dispute the methodology.

Background

This dispute follows a series of federal actions in 2026 aimed at scrutinizing state voter rolls. In September, Governor Newsom signed legislation to protect elections from federal interference. In October, the DOJ threatened to criminally prosecute local election workers who process ballots from individuals identified as noncitizens. This latest lawsuit is part of a broader national effort by the Trump administration to challenge state election administration, which has previously resulted in lost lawsuits in other states like Nevada and Pennsylvania.

How outlets are covering it

CalMatters and The Los Angeles Times emphasize the unreliability of the federal data, noting that Los Angeles County found nearly 40% of the flagged voters were born in the U.S. and that the DOJ has lost 26 similar lawsuits. The Guardian highlights the DOJ’s refusal to share its methodology and the 48-hour deadline given to state officials. Democracy Docket focuses on the procedural significance of the case being assigned to Judge David O. Carter, who previously rejected the DOJ’s legal authority to demand voter data. The DOJ, through Acting Deputy Attorney General Trent McCotter, maintains that the 20,000 figure is a 'floor' and that the state is engaging in 'willful blindness' by refusing to verify citizenship, despite acknowledging the list may contain citizens.

Why it matters

The outcome of this case could set a precedent for federal authority over state election administration in the 2026 midterms. If the court allows the federal government to block ballots based on unverified lists, it could disenfranchise thousands of eligible voters and undermine public trust in the electoral process. Conversely, a ruling against the DOJ would reinforce state control over election integrity and limit federal interference in local voting procedures.

What to watch

Judge David O. Carter will review the emergency request for a restraining order. The DOJ may release the additional 17,000 names of potential noncitizen voters. California officials will continue to comply with grand jury subpoenas for about 300 individuals while opposing the broader ballot segregation order. The November 3 midterm elections will proceed, with the legal battle potentially continuing through the vote counting process.
