Fellow Democrat will run against Rep. Jim McDermott in 2016

SEATTLE (AP) — Longtime congressman Jim McDermott will face a challenge from a fellow Democrat in 2016.

State Rep. Brady Walkinshaw, D-Seattle, told The Seattle Times he'll run for McDermott's 7th District seat. Walkinshaw says he has "incredible respect and admiration" for McDermott but that he thought the area was ready for a change.

McDermott, first elected in 1988, says he will seek a 15th term. His district most of Seattle as well as some surrounding suburbs.

The 31-year-old Walkinshaw is a former Bill & Melinda Gates Foundation program officer. He was appointed to his 43rd Legislative District seat in 2013 to fill a vacancy. He ran unopposed for election in 2014.

McDermott, 78, is known for his liberal views and sharp criticism of the Iraq war. He is a senior member of the tax-policy-writing House Ways and Means Committee.
