Farber is still on: http://crntalk.com/barryfarber/barryfarberfeed
I had no idea that Barry Farber ran for NYC mayor. I remember that I used to listen to his radio program in the 80s and early 90s. He had a great show — very cerebral and folksy at the same time. I think he had a very interesting personal career before radio. He supposedly was a very gifted linguist.
