Republican Bob Onder holds a commanding position in Missouri's 3rd congressional district heading into the November 3, 2026, general election. The incumbent secured his party's nomination in the August 4 primary and benefits from the district's consistent Republican performance in recent cycles, including a 61% margin in 2024. Redistricting adjustments incorporating areas around Columbia have not altered the underlying partisan composition enough to create a competitive environment, as reflected in nonpartisan ratings labeling the seat solidly Republican. Democratic nominee Bethany Mann advanced from her primary but faces structural headwinds in a district where Republican candidates have maintained double-digit advantages. Trader consensus at 91.5% for the Republican nominee accounts for this baseline while leaving room for late developments such as major candidate-specific events or unanticipated turnout shifts to narrow the gap.
