David Brock Smith leads the Oregon Republican U.S. Senate primary market at 68 percent, reflecting traders' assessment of his advantages as the sole sitting state senator in the field. His edge stems from strong fundraising, with nearly $24,000 cash on hand compared to far lower totals for rivals, plus late-April and early-May endorsements from groups such as the Taxpayers Association of Oregon and local conservative officials citing his record on tax measures, wildfire policy, and rural issues. Jo Rae Perkins holds the second spot near 30 percent, buoyed by name recognition from her prior roles as the party's 2020 and 2022 nominee despite earlier defeats. The remaining candidates trail under 2 percent each, with ballots already distributed ahead of the May 19 primary and no recent public polls to alter the current trader consensus.
