Andy Kim sinks first lady Tammy Murphy in NJ Senate race’s first Democratic convention

Rep. Andy Kim wins New Jersey's first Democratic convention in the Senate primary to replace indicted Sen. Bob Menendez .

First lady Tammy Murphy loses in Monmouth County , losing to Kim by a wide margin.

Kim will get the so-called county line, a unique feature of New Jersey’s primary ballot.

Murphy has been presumed the frontrunner because of her high-profile status.

Assemblymember Herb Conaway trounced Assemblymember Carol Murphy , who is not related to Phil or Tammy Murphy .

The next Democratic county convention is Feb. 24 in Burlington County , which Kim is favored to win.

Kim told convention goers before the vote that he wants to codify and protect abortion rights.
