The sprawling 23rd District includes 34 communities in Hunterdon, Somerset, and Warren counties: Alexandria, Alpha, Bedminster, Bethlehem, Bloomsbury, Bound Brook, Bridgewater, Califon, Clinton, Clinton Township, Franklin (Hunterdon), Frenchtown, Glen Gardner, Greenwich, Hackettstown, Hampton, Harmony, High Bridge, Holland, Kingwood, Lebanon Borough and Lebanon Township, Lopatcong, Mansfield, Milford, Peapack-Gladstone, Phillipsburg, Pohatcong, Raritan Borough, South Bound Brook, Tewksbury, Union, Washington Borough, and Washington Township.
Voter registration skews Republican, with more than a third of registered voters identifying with the GOP. Democrats comprise 24 percent of those registered, and most of the rest are unaffiliated.
The district is represented by three Republicans, all of whom are seeking re-election. Sen. Michael Doherty of Oxford is running with Assemblymen Erik Peterson, a Flemington attorney, and John DiMaio, a contractor from Hackettstown.
The Democratic ticket features Christine Lui Chen of Raritan for Senate and Laura Shaw of Lebanon and Isaac Hadzovic of Hackettstown for Assembly.
