Idaho's 2026 Senate contest features incumbent Republican Jim Risch, who secured his party's nomination in the May 19 primary with roughly two-thirds of the vote against limited opposition. The state has not elected a Democratic senator since 1974, and nonpartisan ratings classify the race as safe or solid Republican. Risch's reelection bid draws on his long tenure and prior endorsements, while Democratic nominee David Roth faces structural barriers in a state with a strong partisan voting index favoring Republicans. Trader consensus reflects these factors, with the general election set for November 3, 2026. No major developments in recent weeks have altered the established positioning.
