According to the law, for any postcard that is returned undelivered, or if the clerk is informed the voter resides at a different address than the one provided on election day, the election official must change the status of the voter “from eligible to ineligible on the registration list.” Then the official must mail the voter a notice of the change, “and provide the name of the elector to the district attorney for the county where the polling place is located and the elections commission.”
