David Brock Smith holds the leading position in the Oregon Republican U.S. Senate primary as the sole current state senator in the field, with recent endorsements from the Taxpayers Association of Oregon and local conservative officials highlighting his legislative record on taxes, wildfires, and rural issues. Superior fundraising, with roughly $24,000 cash on hand compared to Jo Rae Perkins' $1,000 as of late March, has reinforced trader consensus on his viability. Perkins maintains the second spot through name recognition from prior Republican nominations in 2020 and 2022, though those general-election losses limit her support. With ballots already distributed for the May 19 primary and no public polls available, the contest remains focused on turnout among Republican voters seeking a nominee to challenge incumbent Sen. Jeff Merkley.
