Former 96th District Rep. David Gregory, R-Sunset Hills, and St. Louis County Councilman Mark Harder of Ballwin have announced their plans to run for the Missouri Senate District 15 seat in the August 2024 primary.

The District 15 seat, which previously covered Sunset Hills before redistricting last year, is currently held by Sen. Andrew Koenig, R-Manchester, who is term-limited in 2024.

Gregory is the former representative of the 96th Missouri House District before he was term-limited in 2022. The 96th House District covers Sunset Hills, Crestwood and portions of Fenton. The seat is currently held by Republican Rep. Brad Christ.

Gregory unsuccessfully campaigned for state auditor in 2022 and was defeated in the August primary by former state Treasurer Scott Fitzpatrick, who went on to become auditor in the 2022 November general election.

After redistricting, Senate District 15 no longer includes Sunset Hills. Gregory lists a Chesterfield address on his campaign paperwork which is part of the district.

Harder, who is the St. Louis County Council vice chairman, represents the 7th District on the County Council.

In a press release Jan. 25 announcing his plan to run for the state senate seat, Harder said there were several issues he would like to address at the state level, including crime, government accountability and tax reform.

Gregory and Harder will face Wildwood Mayor Jim Bowlin in the Republican primary in August 2024. Bowlin announced his intention to run for the seat Jan. 18.

Meanwhile, no Democrats so far have announced their candidacy.
