Third Congressional District

The new Third Congressional District spans from the heart of Mid-Missouri all the way to the St. Louis suburbs and Illinois border.

Incumbent Republican Rep. Bob Onder is being challenged by John Fraser of Columbia.

The Democratic side features three candidates, including the party's nominee in 2024, Bethany Mann. She's up against Paul T. Wilson and Tommy Holstein, both of St. Charles. Libertarian Jim Higgins of St. Louis is also running.

The district includes roughly the southern half of Boone County, including Columbia, along with Callaway, Audrain, Montgomery and Monroe counties.
