Incumbent Republican Senator Mike Crapo's substantial polling leads over Democratic challenger Gary Smith—typically 55% to 28% in recent surveys—drive the 90.5% trader consensus for a Republican victory in Idaho's U.S. Senate race. The state's deep Republican lean (R+18 partisan voter index), overwhelming GOP registration edge, and history of uninterrupted Republican Senate control since 1998 solidify this positioning, unchanged by any major developments in the past 30 days following Crapo's unchallenged primary win. With the November 5 general election approaching, an upset would demand unprecedented shifts like a late scandal, Crapo's health issues, or anomalous Democratic turnout in this non-competitive race.
