Over the weekend, Jay Inslee took the unusual step of publicly endorsing a Democratic challenger to a Democratic incumbent senator.
In the 5th LD, incumbent Mark Mullett faces a general election challenge from his left from Ingrid Anderson.
Mullet has been among the more moderate Democrats in the legislature over the last four years. He lists the support of a range of state and local elected officials on his site.
Anderson is a nurse and a leader in the Washington State Nurses Association. She has won the strong backing of organizations across the full spectrum of the labor community.
