New Jersey is conducting voter-registration audits after a software error incorrectly registered thousands of non-U.S. citizens to vote [1], [2].
The glitch is causing concern across the country because more than half of U.S. states use the same registration vendor [5]. This widespread reliance on a single software provider means a systemic error in one state could potentially exist in others.
Governor Mikie Sherrill (D) and the New Jersey Department of Motor Vehicles identified the issue within the DMV's vendor system [1], [3]. The software error allowed non-citizens to be added to the voter rolls between June 2023 and June 2024 [4].
Reports on the scale of the error vary slightly. One source said over 6,000 non-citizens were registered [1], while another report citing the governor specified the number as 6,600 [2].
Despite the thousands of incorrect registrations, the actual impact on elections appears limited. Fewer than 400 of the erroneously registered non-citizens actually voted [1].
State officials are now working to purge the ineligible names from the rolls to ensure the integrity of future elections. The incident has prompted other states to examine their own systems to determine if the same vendor error affected their registration processes [2], [5].
“More than half of U.S. states use the same registration vendor.”
This incident highlights a critical vulnerability in the centralized nature of election infrastructure. When a majority of states rely on a single private vendor for voter registration, a single coding error can create systemic risks across different jurisdictions. The shift toward audits suggests that states are moving away from blind trust in vendor software toward a model of active verification to prevent non-citizen voting.
