WILMINGTON, Del. — Democratic Congressman John Carney Jr. has won re-election to a second term as Delaware’s lone representative in the U.S. House, exit polling shows.

Carney boasted during the campaign about his ability to work with Republicans, including co-sponsoring three bills passed by Congress. He also formed a bipartisan breakfast club with a Republican lawmaker from Ohio.

But Kovach, the outgoing New Castle County president, said Carney almost always votes with fellow Democrats, and that he would do a better job at forging bipartisan relationships. He argued that Delawareans needed balance in their congressional delegation, which for the first time in some 70 years has all three members from the same party.
