Incumbent Sen. Jim Risch dominates the Idaho Republican Senate primary market at 97% trader consensus, reflecting his three-term tenure, Trump endorsement, and overwhelming fundraising edge with nearly $4 million cash on hand as of late 2025, far outpacing challengers Joe Evans, Denny LaVe, and Josh Roy, who report minimal resources. The March 6 filing deadline confirmed a low-profile field lacking polls or momentum to threaten Risch in Idaho's conservative primary electorate, where incumbents historically prevail. With the May 19 primary approaching, odds imply scant upset risk absent a major scandal, health issue for the 83-year-old Risch, or sudden challenger surge via external funding.
