Key Findings
- Jeff Merkley (D-OR) is a three-term senator from Oregon first elected in 2008 who announced he will not seek re-election in 2026, making the Oregon seat an open race.
- Oregon has voted Democratic in every presidential election since 1988, but Portland's crime and housing issues have made urban politics volatile, and the open seat creates uncertainty.
- Merkley was the only senator to endorse Bernie Sanders in the 2016 primary — he represents the progressive wing of the Senate Democratic caucus on climate, healthcare, and economic inequality.
- As the top Democrat on the Senate Environment and Public Works Committee, Merkley has been a leading voice on climate legislation, including the Inflation Reduction Act's clean energy provisions.
