Incumbent Democratic Sen. Jeff Merkley secured his party's nomination for a fourth term with over 93 percent in Oregon's May 2026 primary, facing Republican state Sen. David Brock Smith, who prevailed in a divided GOP primary. The state's consistent Democratic lean, reflected in recent presidential margins and the Cook Political Report's Solid D rating, underpins trader consensus favoring Merkley at 93 percent. Republicans have not won a U.S. Senate seat in Oregon since 2002, and Merkley's established record and fundraising advantage reinforce this positioning ahead of the November general election. Late developments such as unexpected national political shifts, candidate health issues, or major scandals could still narrow the gap, though no such factors have emerged in the current cycle.
