As expected, U.S. Rep. Leonard Lance fended off two challengers Tuesday to win the Republican nomination to seek a fifth term representing north-central New Jersey's 7th District. Collecting 15,780 votes with 52 percent counted, he defeated businessman David Larsen of Oldwick, Hunterdon County, for the fourth time in a primary contest and first-time candidate Craig Heard of Succasunna, Morris County, another businessman.
