David Brock Smith leads the Republican primary for Oregon’s U.S. Senate seat as the only current state legislator in the field, giving him established name recognition and a record of legislative service in the Oregon Senate since 2023. With the May 19 primary just days away, this incumbency advantage has consolidated trader support around him over repeat candidate Jo Rae Perkins, who previously served as the party’s general-election nominee in 2020 and 2022. Other entrants, including Russell McAlmond, Deborah C. Brown, and several lesser-known challengers, trail significantly due to limited campaign resources and lower statewide profiles. Recent candidate questionnaires and fundraising reports through March 31 show Smith holding a clear edge in visibility ahead of the vote, while the field remains fragmented among the remaining contenders.
