Governor Mikie Sherrill ordered thousands of noncitizens removed from New Jersey's voter rolls after a year-long motor vehicle software error quietly registered them, and nearly 400 of them cast ballots.
Sherrill, a Democrat who won the governor's mansion in 2024, announced Tuesday that her administration had identified approximately 6,600 people who told the state's Motor Vehicle System they were not U.S. citizens but were registered to vote anyway. The error ran from June 2023 through June 2024, a full year in which the system processed driver's license and ID card applications and ignored the applicants' own answers about citizenship. The Washington Examiner reported that Sherrill said she learned of the problem only last week, almost three years after it began.
The governor framed the registrations as an accident, not a policy choice. But the timeline raises a straightforward question: how did a software failure that lasted twelve months and touched thousands of records go undetected for nearly three years?
Sherrill's statement was careful to distance her administration from the failure. She noted the error occurred "almost three years prior to my taking office," placing it squarely during the tenure of her predecessor, former Governor Phil Murphy, who served two terms.
In her public statement, Sherrill described the scope of the problem and what her preliminary review found:
"Last week I learned that a serious software error in New Jersey's Motor Vehicle System led to the registration of roughly 6,600 people who indicated that they were not U.S. citizens between June 2023 and June 2024, almost three years prior to my taking office."
She added that the damage was not limited to registration records. Some of those improperly enrolled residents went on to vote:
"Our preliminary analysis shows fewer than 400 individuals who were newly registered for the first time because of the error voted. They were registered as Democrats, Republicans and Unaffiliated voters and were scattered across the state."
Sherrill emphasized that the noncitizens were registered "through no fault of their own." That may be true. But it sidesteps the more pressing issue: the state built a system that overrode the applicants' own declarations about their citizenship status and then failed to catch the mistake for years.
Homeland Security Secretary Markwayne Mullin responded to Sherrill's announcement on X, and his tone was not congratulatory. Mullin acknowledged Sherrill's action but made clear the federal government had been pushing for it, and that the scope of noncitizen voter registration in New Jersey may extend far beyond the 6,600 names Sherrill identified.
Mullin posted that DHS had sent Sherrill a letter before her announcement and referenced a DHS report published the prior week estimating that New Jersey could have as many as 35,152 potential noncitizens on its voter rolls:
"Appreciate you responding back to our letter, @GovSherrillNJ. This should've been done a LONG time ago. Just ONE illegal vote cancels out the vote of a U.S. citizen. As @DHSgov reported last week, New Jersey could have as many as 35,152 potential non-citizens registered to vote."
If the DHS figure is accurate, Sherrill's cleanup addressed fewer than one in five of the noncitizens potentially sitting on New Jersey's rolls. The governor's statement did not address the 35,152 figure or explain whether her administration plans to investigate beyond the narrow window of the software error. Sherrill's announcement also came roughly one week after President Trump delivered a televised primetime address raising concerns about election integrity, including illegal immigrants voting in U.S. elections and foreign governments accessing voter rolls.
The sequence matters. A governor who has clashed publicly with federal immigration enforcement moved to clean voter rolls only after DHS put a number on the problem and the White House put election integrity on national television.
New Jersey is not the first state to confront noncitizens on its voter rolls, and the political pattern is familiar. In Virginia, Republican Governor Glenn Youngkin used data from the DMV and Social Security Administration to remove more than 6,000 noncitizens and nearly 80,000 deceased voters from the state's rolls over a two-and-a-half-year period. Youngkin also issued Executive Order 35, which mandated 100 percent paper ballots with counting machines not connected to the internet.
"We went to work to make sure that with data feeds from the DMV and for the Social Security Administration, if you are a non-citizen, you were removed from the voter rolls over the last two and a half years," Youngkin said. "We got 6,000 of them."
Virginia's cleanup did not go unchallenged. The Biden Justice Department sued the state over the purge program, and a Biden-appointed federal judge initially blocked it, citing the National Voter Registration Act's 90-day "quiet period" provision, a rule that restricts systematic voter roll changes close to an election. The case reached the Supreme Court, which ruled in Virginia's favor, allowing the state to proceed with removing approximately 1,600 suspected noncitizens just days before the 2024 election. The three liberal justices dissented.
RNC Chairman Michael Whatley framed the Virginia fight in stark terms: "With only one week to our country's most important election, Democrats are now taking extraordinary measures to keep non-citizens on voter rolls."
The Virginia precedent makes Sherrill's situation more difficult to dismiss. A Republican governor cleaned voter rolls proactively, faced a federal lawsuit for doing so, and won at the Supreme Court. A Democratic governor in a neighboring state let a software error run for a year, left the bad registrations in place for nearly three more years, and acted only after DHS flagged the problem in writing.
Sherrill's statement confirmed that fewer than 400 of the improperly registered individuals actually voted. She noted they were spread across party lines, registered as Democrats, Republicans, and unaffiliated, and scattered across the state. The bipartisan distribution may blunt any argument that the error was designed to benefit one party, but it does not resolve the core problem.
Every one of those votes canceled out a lawful ballot cast by a U.S. citizen. Mullin's point, "Just ONE illegal vote cancels out the vote of a U.S. citizen", is not rhetoric. It is arithmetic. And Sherrill's statement did not say whether any of the nearly 400 individuals who voted face legal consequences, or whether the state has referred the matter to prosecutors.
Sherrill has positioned herself as a vocal opponent of federal enforcement actions in New Jersey. She was turned away from an ICE detention center amid protests and a hunger strike, and she and a state senator chose Memorial Day to protest at an ICE facility. That record makes her sudden interest in removing noncitizens from voter rolls look less like leadership and more like a reaction to federal pressure she could no longer ignore.
Republican members of Congress have pushed the SAVE America Act, which would require photo identification and other safeguards for Americans to vote. Democrats have pushed back, arguing the legislation could hinder some legal voters. The New Jersey debacle hands Republicans a concrete example of what happens when states rely on honor-system software to keep noncitizens off the rolls, and the software fails.
The broader political landscape has shifted. Democratic voters have shown a willingness to reject their own party's preferred candidates, and election integrity has become a live issue that cuts across traditional party lines. Sherrill's own data shows that the improperly registered noncitizens were not clustered in one party, they were Democrats, Republicans, and unaffiliated voters. The problem is systemic, not partisan.
The open questions remain substantial. The DHS report's 35,152 figure dwarfs the 6,600 names Sherrill removed. What accounts for the remaining 28,000-plus potential noncitizen registrations? What methodology produced that estimate? Did the software error affect other state systems or other time periods? And why did it take a DHS letter and a presidential address on election integrity to prompt a governor to act on a failure that started in 2023?
Sherrill deserves credit for ordering the removals. But cleaning up 6,600 names after three years, under federal pressure, while a DHS report suggests the real number is five times higher, is not election integrity. It is damage control.
When a state's own system ignores what applicants say about their citizenship and nobody notices for years, the problem is not a software glitch. It is a government that was not looking.
