State Sen. David Brock Smith leads the Republican primary for Oregon’s U.S. Senate nomination, backed by his current legislative record on rural issues, wildfire policy, and tax measures, plus recent endorsements from the Taxpayers Association of Oregon and local conservative officials. Ballots mailed in late April for the May 19 contest have highlighted his superior cash position over perennial candidate Jo Rae Perkins, who previously carried the GOP banner in 2020 and 2022. Traders assign Smith the dominant share of the outcome, reflecting his path through a fragmented field and established party infrastructure in a state where Republicans face long odds against incumbent Sen. Jeff Merkley in November.
