The three unaffiliated candidates who will be on the November gubernatorial ballot are appearing together at West Conn on Friday morning for a town hall forum.  Libertarian Rod Hanscomb, Oz Griebel--running in a party named for him--and Mark Stewart for the Amigo Constitution Party will participate.  Assistant Professor Howell Williams says they previously hosted an event with Democrat Ned Lamont and have been working to have Republican Bob Stefanowski appear in Danbury.  The three candidates will take part in the forum scheduled for 11am at White Hall in Room 127 on the midtown campus.  Williams teaches a course on state and local government, and his students will attend.  He expects other West Conn students from classes on American government and the social sciences to be there.  The event is open to the public.
