Washington's 1st District Primary

Democratic incumbent Suzan DelBene heads into Washington's 1st District primary on Aug. 4, as the commanding favorite in a seven-candidate field that spans Democrats, Republicans, and at least one independent. All candidates share a single ballot under Washington's top-two primary system, and the top two finishers advance to the Nov. 3 general election regardless of party.

Washington's 1st Congressional District is a U.S. House seat in the northwestern corner of the country. The district has drawn Democrats, Republicans, and independent candidates this cycle, with seven active candidates competing for two spots on the November ballot. Five candidates are already slated for the general election stage, reflecting the structure of Washington's top-two process, in which the general election field is defined after primary results are certified.

The district carries a strong Democratic lean. Cook Political Report, Sabato's Crystal Ball, and Inside Elections all rate the seat "Solid Democratic," and prediction markets place the Democratic win probability at nearly 97 percent heading into primary day. Total fundraising across all candidates in the race has reached roughly $3.67 million.

The Candidates

DelBene faces Hunter Gordon, Catherine Hildebrand, Benjamin Kincaid, and Bryce Nickel in a crowded Democratic field. Mary Silva is running as a Republican, and James Etzkorn is running under the Independent Party.

The Money Behind the Race

Combined fundraising across all candidates in the race totals approximately $3.67 million, according to Federal Election Commission (FEC) records as of Aug. 3. Delbene's campaign finance blows her competition out of the water. She raised $3.5 million, whereas Hunter, James, and Silva each raised $98,588, $21,786, and $3,186, respectively.

Outside spending in the race is negligible by any measure. Sierra Club Independent Action is the only outside group on record, and its total reported independent expenditure is $10, all of it directed in support of DelBene. No communication costs have been reported. No outside group has spent a dollar opposing any candidate in the race.

Ratings vs. Odds

Cook Political Report, Sabato's Crystal Ball, and Inside Elections all rate Washington's 1st as "Solid Democratic." Cook issued its rating July 16, Inside Elections on June 30, and Sabato's Crystal Ball on July 30. The three outlets reached the same conclusion independently, and the consensus rating as of July 30 reflects that unanimous alignment.

On Kalshi, Democrats hold a 96.8% win probability as of Aug. 3, with Republicans at 3.2%. The market has recorded 12,139 contracts traded on the race. No independent candidate probability is listed.
