From the City Newspaper:

The Green Party of Monroe County has received “several” applications from people interested in running for Rochester mayor on the Green Party line, says party co-chair Scott Brant. Citing confidentiality and respect for the applicants, Brant would not give a specific number. He did say that he is “thoroughly impressed” by the quality of the applicants…

With little risk, I think we can assume that two of the applicants are likely former Mayor Bill Johnson and Rochester businessman Alex White. Johnson has said that he’s seeking third-party lines, and White has announced his intention to seek the Green Party endorsement.
