Provide a contribution limit for candidate committees under the Nebraska Political Accountability and Disclosure Act

This bill establishes a $1,000 annual limit on individual contributions to candidate campaign committees in Nebraska during an election year. Campaign committees must refund any contributions exceeding this amount within 10 days and report the details, including the donor's name and address. The limit applies to all donations received during the calendar year of an election but does not cover funds a candidate personally contributes to their own committee. This amendment modifies Nebraska's campaign finance rules to standardize contribution restrictions under the Political Accountability and Disclosure Act.
