Democrats secured 11 of New Jersey’s 12 U.S. House seats in the November 3 election, flipping the Republican-held 2nd and 7th districts while retaining their prior nine. Zack Mullock defeated incumbent Jeff Van Drew in the 2nd, and Rebecca Bennett ousted Tom Kean Jr. in the 7th, with both races decided by narrow margins that required extended vote tabulation. Chris Smith remained the sole Republican winner in the 4th. Trader consensus favoring 11+ over 10 reflects these confirmed flips and the statewide results, though final certification of mail-in and provisional ballots in competitive districts sustains some probability for a 10-seat outcome pending official state review.
