The Missouri 5th congressional district race features Democratic incumbent Emanuel Cleaver facing Republican nominee Rick Brattin in the November 2026 general election. Recent redistricting enacted during a 2025 special session transformed the previously Democratic-leaning seat into a solidly Republican district, reflected in ratings such as R+18.3. Brattin secured the GOP nomination in the August 2026 primary, while Cleaver advanced unopposed on the Democratic side. These factors, combined with the district's altered partisan composition and historical voting patterns, underpin the market's assignment of an 83.5% implied probability to a Republican victory. No major late developments have altered this positioning in recent weeks.
