With ballots mailed April 29 for Oregon's May 19 Republican U.S. Senate primary, trader consensus gives state Sen. David Brock Smith a narrow edge at 48% implied probability over Jo Rae Perkins at 39%, driven by his recent endorsements from the Oregon Taxpayers Association and Oregon Right to Life, which emphasize his record on rural issues like wildfire prevention and estate tax relief for family farms. Perkins retains strong grassroots backing from her 2022 primary victory, sustaining a tight contest in a fragmented nine-candidate field where turnout among conservative base voters could prove decisive. Late developments such as additional endorsements, fundraising reports due soon, or early ballot trends may create separation before polls close.
