Incumbent Democrat Val Hoyle maintains a commanding lead in Oregon’s 4th congressional district due to her established position, strong primary performance, and the district’s underlying partisan lean. Hoyle secured her Democratic nomination with over 75% of the vote in May 2026 and continues to highlight federal funding secured for Oregon infrastructure, habitat restoration, and housing projects. Republican challenger Monique DeSpain, a retired Air Force colonel and attorney who lost the 2024 rematch, has focused recent attacks on data center growth, AI-related spending, and utility costs, while remaining competitive in fundraising. Forecasters rate the race Solid Democratic, reflecting limited movement despite emerging campaign themes. A late scandal, national partisan wave, or significant polling shift could still narrow the gap before the November 3 general election.
