Whenever, in the judgment of the filing officer, two or more candidates have filed for the same office whose names are so similar as to be confusing to voters, he or she shall differentiate between the candidates by the inclusion of additional information in connection with the name as it appears on the ballot. Such differentiation may be made by the inclusion of the candidate's occupation, status as incumbent or challenger, or by any other means which, in the judgment of the filing officer, fairly and impartially distinguishes the candidates. The filing officer may solicit suggestions and input from the candidates involved in order to resolve the situation.
