The Department of Justice, on August 14, indicated to the state of Nevada its intent to search for non-citizens on the voter registration rolls of the state (go here).

At least seven states have attempted to locate non-citizens on voter registration rolls. Each attempt failed to find more than an extremely small number, and these could be database errors. They are Georgia, Texas, New Hampshire, Florida, South Carolina, Virginia and Ohio (go here).

The motor vehicle registration systems include citizenship status. Investigations to match MV registration data with voter registration data tend to come up with a relatively tiny number of instances where the MV database shows non-citizenship and the person is a registered voter. The common flaw in all attempts is the assumption that the matching databases are up to date and that all entries are 100% what the party intended. It is possible that the individual forgot to change their MV data upon naturalization. It is also possible that a naturalized citizen mistakenly recorded themselves as a non-citizen in their MV record.

The Ohio caper, the most recent effort (in 2024) resulted in a finding of several hundred records, for which the errors noted above had not been audited. The number of such cases were one in 13,000 registered voters.
