Philadelphia Mayor John Street is a colorful and engaging political figure — he’s also widely believed to be quite corrupt. Earlier this month, an FBI-placed bug was discovered in Street’s office, and yesterday the FBI raided several city offices and Street’s fundraiser. Street partisans claim this is all a calculated effort to hurt Street’s reelection chances this November, and dismiss the long history of corruption within Philadelphia’s Democratic political machine. Despite a major advantage in voter registration, Street faces a strong Republican challenger in Sam Katz. It is beginning to appear he may soon face an indictment as well.
