Incumbent Republican Jim Risch secured reelection in Idaho’s U.S. Senate race on November 3 with roughly 56.5% of the vote to independent Todd Achilles’s 33.6%, producing a margin near 23 points once nearly all ballots were counted. Early returns showed Achilles briefly ahead in some urban precincts before Risch’s rural and suburban strength produced a steady lead; the Associated Press called the race shortly after 11 p.m. Mountain Time. Achilles, a former Democratic state legislator running as an independent after the sole Democrat withdrew in July, mounted the most visible challenge in decades yet could not overcome Idaho’s long-standing Republican dominance and Risch’s incumbency, fundraising, and foreign-policy profile. With final certification pending and minor additional ballots still possible, trader consensus on the precise margin bucket remains fluid, reflected in elevated pricing on “Other” alongside the 20-25 and 25-30 point Republican ranges.
