In the 2026 Idaho U.S. Senate race, trader consensus centers on mid-range turnout around 680,000-720,000 ballots, reflecting a low-competition general election on November 3. Incumbent Jim Risch holds a strong lead in most likely-voter polls despite polling variance between campaigns, while independent Todd Achilles serves as the main challenger after Democrat David Roth withdrew in late July. Primary turnout reached about 30 percent in May, slightly above historical medians amid some legislative contests, but the general election lacks comparable mobilization in this solidly Republican state. Factors such as limited fundraising gaps, Risch's incumbency, and subdued voter enthusiasm in a non-presidential cycle support expectations for turnout below 2024 levels. Late developments in registration trends or national conditions could shift probabilities among the clustered mid-range outcomes.
