District 27 encompasses 14 communities in Essex and Morris counties: Caldwell, Chatham Township, East Hanover, Essex Fells, Florham Park, Hanover, Harding, Livingston, Madison, Maplewood, Millburn, Roseland, South Orange and West Orange.
The district swings “blue,” with 36 percent of voters registered as Democrats, 21 percent Republicans, and most of the rest unaffiliated.
Both Democrats representing the 27th in Trenton are seeking re-election. Assemblyman John McKeon, of West Orange, is an attorney who joined the lower house in 2002., of South Orange, is a former member of the South-Orange-Maplewood Board of Education who is in her ninth term in the Assembly.
They are challenged by Republicans Tayfun Selen of Chatham and Wonkyu "Q" Rim of Whippany, and Libertarians Damien Caillault of Livingston and Jeff Hetrick of Chatham.
