Provide for confidentiality of certain candidate filing form information for judges filing for retention

LB 334 makes the residence address, mailing address, and telephone number of judges seeking retention confidential. This applies only to judges running for retention (a process where voters decide whether to keep an incumbent judge) and not to other candidates. The bill requires filing officers (like the Secretary of State) to keep this contact information private, removing it from public candidate filing forms. It does not change voting rules or election procedures, only the confidentiality of specific personal details for judges in retention races.
