Missouri State Senate District 15

Senate District 15 Voting History

More to the point, while Trump carried the state by 15% in 2020, Biden earned 48.3 percent of the vote that year in the District, and Trudy Busch Valentine earned 49.11% of the vote in her bid to defeat Eric Schmitt in the 2022 U.S. Senate race.


The SD-15 senate seat will be vacated by termed-out Andrew Koenig-R. (Three Republicans will be battling it out in the Aug. 6 primary. Joe is the lone Democrat thus far.)  A large turnout is expected with the oval office on the ballot, as will be an IP to end the strict ban on abortion in this state.
