The 16th District includes 14 communities in Hunterdon, Mercer, Middlesex and Somerset counties: Branchburg, Delaware, Flemington, Hillsborough, Manville, Millstone, Montgomery, Princeton, Raritan, Readington, Rocky Hill, Somerville, South Brunswick and Stockton.
Voter registration leans Democratic — 36% blue and 24% red. While unaffiliated voters used to swing the results to the GOP, this is now a split district.
The 16th currently has a Republican senator and two Democratic assemblymen. Sen. Christopher (Kip) Bateman is retiring and will not seek reelection.
Assemblyman Andrew Zwicker of South Brunswick is running for the Senate and could become the first Democrat to represent the district in the Senate. Trying to keep the seat in Republican hands is former one-term Congressman Michael Pappas, the Bridgewater Township administrator and a Branchburg resident.
In the Assembly race, incumbent Roy Freiman of Hillsborough is running with fellow Democrat and former Montgomery Mayor Sadaf Jaffer. The Republican candidates are Vincent Panico, a Readington man who is president of the Hunterdon Central Regional Board of Education, and Joseph Lukac III, a U.S. Army veteran and Manville councilman.
