Mike Jones’ departure removes the incumbent from a seat Republicans won by only 179 votes, giving Tracey Steele - who held a three-to-one cash advantage in late July - the clearest opening against Jerry Hickey.

Jon Patterson’s departure gives returning Democrat Kevin Grover an opening against Jeff Martin in a nearly even presidential district where Republicans must replace the speaker’s demonstrated crossover appeal.

Philip Oehlerking’s 143-vote escape in 2024 leaves little protection against Mary Ann Perkins, whose abortion-rights organizing gave her experience canvassing the same neighborhoods she now seeks to represent.

Bill Allen’s 639-vote reelection margin gives retired educator Susan Hoisington a shorter distance to travel than most Democratic challengers, although Allen retains the advantages of an incumbent who has survived twice.

Colin Wellenkamp’s six-point first victory leaves Cat Clayton a credible opening, with fresh Republican advertising emphasizing his independence suggesting that protecting this seat requires more than relying on its Republican history.

Springfield is turning more purple.  So this is one to watch. Melanie Stinnett’s Senate run gives Katelyn Zach an opening against Jerry Angelo.

Chesterfield voted for Kamala Harris but reelected Ben Keathley by nine points. That means Paul Lentz has favorable terrain.  His big challenge is persuading voters who have already demonstrated that they distinguish Keathley from the Republican ticket.

Jim Murphy is leaving, but the Murphy name remains on the ballot through his wife, Maryellen. A Trump-plus-seven district and that family continuity make this a harder flip than the other open suburban targets.

Jeremy Dean’s 341-vote win and formal reprimand give HRCC-supported Russ Gosselin a serious opening, making this my strongest Republican pickup prospect despite the broader headwinds facing the GOP.

Brad Christ won by ten points while Harris carried his district by five – a substantial demonstration of crossover appeal.

Democrats recruited retired union electrician Dan Kinate in a district Kamala Harris carried by a whisker. Chris Brown nevertheless won by eleven points last time, making this a plausible pickup, but running against a substantial incumbent advantage to overcome.

Travis Wilson’s two mid-50s victories leave Democrats an opening if the suburban swing reaches beyond their top targets. Air Force veteran Jewel Kelly’s selection for national Democratic support makes this worth watching, though Wilson is favored.

Tara Murray’s rematch with freshman Terri Violet belongs on the list because her ten-point loss in 2024 puts this seat within the same competitive range as several Republican districts already ranked.

Marty Jacobs’ 515-vote flip of this Liberty seat leaves Republican nurse Mary Hill a credible opening, making it an overlooked Democratic defense even with Jacobs now enjoying incumbency.

Stephanie Hein’s 365-vote reelection keeps Jacey Buckles in contention, but two victories and Missouri Chamber backing give Hein more protection than her narrow margin alone suggests.

Sean Smith remains a recognizable Republican challenger, but Kemp Strickler’s larger second-election margin and Missouri Chamber endorsement make this a less promising pickup than its earlier razor-thin result suggested.

Will Jobe’s 312-vote victory warrants continued attention, but I found no fresh evidence strong enough to elevate Michael Young’s challenge above the more clearly developing battlegrounds.

Claire Heinrich’s DLCC support merits monitoring, but the previous Republican’s 25-point victory put this race near the bottom of the Rankings.

Marine veteran Justin Geiser gives Democrats a credible challenger, but Ron Fowler’s decades on the Blue Springs City Council and eleven-point win last cycle make this a tougher flip.
