TRENTON - Newark Mayor Cory Booker has won New Jersey's special election for U.S. Senate.

He defeated Republican candidate Steve Lonegan by 11 percent of the vote. Booker was an early favorite in the race, and while the margins closed toward the end, Booker says his campaign always expected to win by double digits.

Booker says he looks forward to working with senior U.S. Sen. Robert Menendez. "Together we can be one of the best duos New Jersey has had in a long time," says Booker.

The senator-elect will take over the seat vacated after the death of Sen. Frank Lautenberg in June. Former state Attorney General Jeff Chiesa had been holding the seat in the interim.

Some of the big issues facing the new senator will be passing a federal budget, a farm bill and immigration reform.

Booker, the first African-American from New Jersey and the fourth ever to be elected to the U.S. Senate, will serve a term lasting for 15 months.
