N.J. Senate race: Tammy Murphy has the alliances, Andy Kim has the momentum

In her bid for the U.S. Senate, N.J. First Lady Tammy Murphy has huge advantages. But she is behind Rep. Andy Kim in a recent poll, and has lost the first three county conventions where Democrats vote to give out endorsements.

Murphy has alliances throughout New Jersey's Democratic Party leadership, and endorsements from several powerful influences. But Kim's an experienced campaigner, and appears to be quickly gaining support among rank-and-file party members.
