Incumbent Republican Ann Wagner secured her party's nomination with nearly 74% in the August 4 primary, while Democrat Fred Wellman narrowly won his contest at 46%. The district's Republican lean, reflected in its R+6 to R+9 Partisan Voter Index and recent election margins, underpins trader consensus favoring the Republican nominee at 66.5%. Wagner has held the seat since 2012 with consistent double-digit victories, and independent forecasters rate the race Solid or Safe Republican. A May internal poll showed a close head-to-head, but the absence of major shifts since primaries and the district's voting history sustain the current pricing ahead of the November 3 general election.
