On July 12, the Socialist Workers Party said it will petition to place its nominee for Mayor of Philadelphia, Pennsylvania on the November 3 ballot. The nominee, Osborne Hart, needs 1,819 valid signatures by August 3, 2015.
This is the biggest petition the Socialist Workers Party has attempted since 2012, when it placed its presidential nominee on the Minnesota ballot. That petition required 2,000 signatures.
As far as is known, no other minor party or independent candidate is attempting to get on the ballot for Mayor of Philadelphia. Philadelphia has partisan city elections. Thanks to Independent Political Report for the news.
