Incumbent Republican Ann Wagner secured her party's nomination in the August 4 primary with nearly 74% of the vote and enters the November 3 general election against Democrat Fred Wellman in a district that favored Republican presidential and House candidates by 8–12 points in 2024. Nonpartisan forecasters rate the contest Solid or Likely Republican, reflecting the seat's established partisan lean and Wagner's long tenure since 2013. A Democratic internal poll from late May showed the race within 3 points after voters heard biographies, though broader indicators point to continued Republican advantage. The Missouri Supreme Court's September 4 ruling preserving prior district lines slightly increased competitiveness without altering most race assessments. Traders assign the Republican nominee a 66.5% implied probability, consistent with the district's history and limited recent shifts in polling or endorsements.
