Idaho’s entrenched Republican lean shapes trader expectations for the 2026 Senate contest. Incumbent Jim Risch’s decision to seek another term, backed by strong primary polling and key endorsements, has reinforced expectations of a comfortable general-election victory in a state that has not elected a Democrat to the Senate since 1974. The primary on May 19 will likely produce the Republican nominee with minimal disruption, leaving the general-election outcome heavily influenced by the state’s consistent partisan voting patterns. A Republican win remains the clear market favorite, yet an unforeseen development such as a major scandal, health event, or sharp national political shift could still alter the final margin before November.
