Will the Republican Party candidate win the 2026 Idaho Senate election by 40% or more?

The question asks whether the Republican candidate will win the 2026 Idaho Senate election by a margin of 40% or more. Idaho is a deeply Republican state; the last several Senate races have been won by Republicans by very large margins (e.g., 2016: 66%–27%, margin 39%; 2020: 63%–33%, margin 30%; 2022: 61%–36%, margin 25%). The 40% threshold is high but not unprecedented given Idaho's strong Republican lean. The provided news articles do not directly address Idaho or the 2026 Senate race; they focus on national trends, Trump's influence, and voter trust in other states Ground WisconsinReuters articleNYT articleAljazeera RepublicansGround TrumpAljazeera Trump. None of these articles provide specific polling or candidate information for Idaho. Without contrary evidence, the historical pattern in Idaho suggests a Republican win by a large margin, but the 40% threshold is at the upper end of recent margins. Given the lack of specific information and the possibility of a closer race due to national trends or candidate quality, a probability of 0.65 reflects a moderate confidence that the margin will reach 40% or more, but with significant uncertainty.
