Trenton, N.J. — Democratic Rep. Andy Kim won New Jersey’s Senate primary Tuesday, putting him in strong position for the general election in the blue-leaning state, though the win comes a day after Democratic Sen. Bob Menendez filed to run as an independent amid his federal corruption trial. Kim, a three-term congressman who launched his campaign after charges against Menendez were announced last year, rose to the top in the state’s dominant political party over a relatively short period.
