Newtown Township voters cast their ballots for Democrats Tuesday.
Democrats Phil Calabro and Linda Bobrin won six-year terms of the Board of Supervisors and John Mack won a two-year seat.
Republicans Laure Gensbauer, Jerry Festa and Gerry Couch were both several hundred votes behind their Democratic opponents in the election, according to unofficial county vote counts.
The win will change the makeup of the Board of Supervisors to a Democratic majority come the new year.
Couch, a local businessman, was appointed to the Board of Supervisors last year after Michael Gallagher left to take the helm as Bucks County Controller, a position which he lost Tuesday.
