(1)    Except as provided in sub. (4), after the death of a candidate nominated for a partisan office, either in a primary or when no primary is required under s. 8.50 (3) (b), the vacancy may be filled by the candidate’s political party. In the case of county offices, the vacancy shall be filled by the chairperson of the county committee. If no county committee exists, the vacancy shall be filled by the chairperson of the state committee. For other offices, the vacancy shall be filled by the chairperson of the state committee. The appropriate chairperson shall file with the official or agency with whom nomination papers are filed for the office a certificate signed, certified and sworn to the same as an original nomination paper.
