Elections for the Missouri State Senate took place in 2024. The general election was on November 5, 2024. The primary was August 6, 2024. The filing deadline was March 26, 2024.

There were nine contested Republican primaries for the Missouri Senate on August 6, 2024. An incumbent ran in two of those primaries, and seven of those primaries were open, meaning an incumbent did not seek re-election in those districts.

Ballotpedia identified the Republican primaries in Districts 3, 15, 21, 23, and 27 as battleground primaries, all but two of which were for open seats. The Missouri Senate had the most turnover since the state implemented term-limits in 2002. Of the nine members leaving the chamber in 2024, six left due to term limits. Three of those six senators—Sen. Bill Eigel (R), Sen. Denny Hoskins (R), and Sen. Andrew Koenig (R)—were members of the Missouri Freedom Caucus.[1] Of the two other members of the Senate who formally identified as Freedom Caucus members, Sen. Rick Brattin (R) advanced from the Republican primary in District 31, and Sen. Nick Schroer's seat was not up for election.

The 2024 primaries took place in the context of a conflict among Senate Republicans over the future of the party. According to Jonathan Shorman and Kacen Bayless of The Kansas City Star, two groups of Republican senators "have grown more divided this session after senators announced the formation of the new Freedom Caucus with backing from the national States Freedom Caucus."[2] Several Senate Republicans who were not members of the Freedom Caucus criticized the group for their use of the filibuster after the Freedom Caucus filibustered approval of the chamber's journal, a committee referral increasing threshold requirements for initiative petitions to qualify for the ballot, approval of a new congressional map, and the state's budget.[3][4][5]

Following the Caucus' January filibuster of a bill that increased requirements for initiative petitions to qualify for the ballot, President Pro Tempore Caleb Rowden (R) removed four Republican senators who identified with the Freedom Caucus from their committee chairmanships.[3] In explaining why he removed caucus members from their chairmanships, Rowden criticized the caucus' filibuster efforts and said they made it too hard for the Senate to pass legislation. Rowden said, "They [filibustered] repeatedly, day after day for two weeks, basically...It became necessary for us to do something that would indicate that we’re not going to let four guys run the place; it’s just not how this works."[6]

Several members of the Freedom Caucus, including Sen. Bill Eigel (R), said Republicans outside of the Freedom Caucus, including Rowden, opposed the caucus because he believed they tried to preserve power. Eigel said, "It’s never been about policy for them. It’s been about individuals trying to preserve power at the expense of what we believe are the issues that Republicans sent us to Jefferson City for."[7]

Missouri was, at the time of the election, one of 23 states with a Republican trifecta. A state government trifecta is a term used to describe a single-party government where one political party holds the governor's office and a majority in both chambers of the state legislature.

The Missouri State Senate was one of 85 state legislative chambers with elections in 2024. There are 99 chambers throughout the country.

Battleground primaries

Ballotpedia identified eight contested Republican primaries as battleground primaries, all of which were in open districts.

District 3

Did the incumbent file to run for re-election?

No

What made this a battleground race?

Rep. Cyndi Buchheit-Courtway (R) and Rep. Mike Henderson (R) ran for the Republican primary in District 3. Incumbent Sen. Elaine Gannon (R) did not file for re-election, leaving the district open.[8] Both Buchheit-Courtway and Henderson commented on the Senate's productivity in 2024.
  • Buchheit Courtway said, "At the beginning of this term, leadership in the House changed the process of how bills were assigned and moved through committees. As a chair, we were only allowed to send two bills out of committee to move on through the process. This led to omnibus bills, and in turn ensured that very few bills made it on to the floor, or out of the House. Also, the Senate spent valuable time attacking each other, filibustered the last two weeks of session, and went home before session ended. Many good pieces of legislation died as a result.[8]
  • Henderson said, "Quite frankly, I think the Senate needs an attitude change. I know that we’re not going to be able to pass the conservative legislation we need if we keep electing people who are just there to run for higher office and, as a result, are more focused on generating the perfect sound bite for radio or TV than they are on the needs of their district. I have proven that I know how to pass conservative legislation, and I am a hard worker."[8]

District 15

Did the incumbent file to run for re-election?

No

What made this a battleground race?

Former Rep. David Gregory (R) won the Republican primary in District 15. Gregory received 40.8% of the vote. Mark Harder (R) finished in second with 34.1%, and Jim Bowlin (R) finished in third with 25.1%. Incumbent Sen. Andrew Koenig (R) could not run for re-election due to term limits, leaving the district open. Koenig was a member of the Freedom Caucus.[9] Bowlin and Harder commented on the Senate's productivity in 2024 in a questionnaire.[10]
  • Bowlin said, "We need a senator who will stand strong for District 15, and work with members of the Republican party without engaging in personal agendas. We need a statesman. As mayor, my city installed livestream cameras in all our public meeting rooms so any member of the public can always see not just how we vote – which the meeting minutes show – but how we acted on your behalf. I cleaned up the third largest municipality in St. Louis County by eliminating inefficiencies and following the rules. I’ll do the same thing in Jefferson City. Let’s get it done!"[10]
  • Harder said, "To address the legislative inefficiency, we need to foster better collaboration and focus on prioritizing key issues. Streamlining the legislative process, reducing bureaucratic red tape, and building consensus on critical matters can ensure that essential bills are passed and our state progresses."[10]
  • In a press release, Gregory said, "We can’t afford anymore soft, do-nothing Republicans. It’s time to get bold and drive home the conservative agenda. We’re coming.”[11]

District 21

No

What made this a battleground race?

Rep. Kurtis Gregory (R) won the Republican primary in District 21. Gregory received 56.6% of the vote. Doug Richey (R) finished in second with 43.4%. Incumbent Sen. Denny Hoskins (R) could not run for re-election due to term limits, leaving the district open. Hoskins was a member of the Freedom Caucus.[9] Both candidates commented on what their legislative philosophy would be if elected.
  • Gregory's campaign website said, "In the Missouri Senate, Kurtis will stand against radical woke policies and shield our family farms and businesses from tax hikes. He knows firsthand the damage done to our economy by out-of-touch elitists. In the senate, Kurtis will remind career politicians they work for We The People."[12]
  • Richey completed Ballotpedia's Candidate Connection survey. In it, he said, "This race is not ultimately about politics. It's about life. It's about your life, your way of life, your livelihood, and the life you hope that your kids and grandkids can enjoy. All of which, should be valued and protected. I'll continue to do all that I can to protect against the leftist attack upon what's most important."

District 23

No

What made this a battleground race?

Rep. Adam Schnelting (R) won the Republican primary in District 23. Schnelting received 50.3% of the vote. Rep. Phil Christofanelli (R) finished in second with 27.7%, Rich Chrismer (R) finished in third with 15.4%, and Dan O'Connell (R) finished in fourth with 6.5%. Incumbent Sen. Bill Eigel (R) could not run for re-election due to term limits, leaving the district open. Eigel, who ran in the Republican primary for governor of Missouri, was a member of the Freedom Caucus.[9] All four candidates completed a Missouri Drivers News Magazine survey in which they were asked, "What is the biggest need for residents in District 23, and how will you address it?"[13]
  • Christofanelli said, "St. Charles must remain a safe place to live. Serious property and violent crimes are increasing as criminals from St. Louis make their way out into the region. The residents of St. Charles County do not want to see our county become St. Louis. In the legislature, I helped to secure increased funding for our police departments to ensure they have the resources and training necessary to effectively protect and serve our community. Additionally, I will make sure our courts and legal system are well-equipped to ensure violent criminals aren’t let off easily."[13]
  • Schnelting said, "One of the biggest needs that I hear from my constituents is that they need to be able to trust their elected officials to keep their word. Republicans campaign on their “conservative” ideals but often do not govern in a conservative fashion. I have run on a conservative platform, promising the protection of our kids, limited government and fiscal responsibility."[13]
  • O'Connell said, "I’m running because it feels like we have been stuck in survival mode since 2020, afraid to talk to our neighbors because they might think differently than us, afraid to ask for a raise because we can’t risk losing our healthcare. Even basic decency is falling away, because we don’t have a basic level of trust in society outside of who we know. We deserve real leaders who haven’t sold out their constituencies to climb the ladder of national politics. I have fought for our constitutional rights, helped our children and built businesses. St. Charles will always be my priority."[13]
  • Chrismer said, "Inflation and tax relief. The cost of living has increased to a level not seen in many years. Businesses are hurting to the point of downsizing or worse, going out of business. The high cost of groceries and gasoline has families’ budgets stretched to the limit. As state representative, I passed the largest tax cut in state history eliminating state grocery tax from the state budget – a cost savings to the citizens of Missouri of over $13 billion, or over $600 million each year. I will continue that fiscally responsible practice in the Missouri Senate."[13]

District 27

Did the incumbent file to run for re-election?

No

What made this a battleground race?

Rep. Jamie Burger (R) won the Republican primary in District 27 with 40.9% of the vote. Jacob Turner (R) finished in second with 37.2%, and Rep. Chris Dinkins (R) finished in third with 21.9%. Incumbent Sen. Holly Rehder (R) did not run for re-election because she is running for Lieutenant Governor of Missouri. All three candidates completed a Southeast Missourian survey in which they were asked, "Why are you running for Senate?"[14]
  • Burger said, "Our state, more than ever, needs experienced leaders to address the 'challengers' both short and long-term. We are in a war with the federal government over the border, fighting to protect our fundamental liberties, the Second Amendment and the sanctity of life and fighting woke directives that impact almost every business and government institution. It is a fight that I feel very confident I can impact as a state senator."[14]
  • Dinkins said, "I’m running for Senate to protect our conservative values, support small businesses and ensure Missouri families thrive. I am a lifelong conservative Republican and small business owner with the ability to make impactful changes. I am the only candidate endorsed by Missouri Right to Life, the only candidate to sponsor a complete ban on the foreign ownership of Missouri land, the only candidate to vote against the gas tax and the only candidate to endorse President Trump in 2016, 2020 and 2024."[14]
  • Turner said, "I am running because business as usual isn't working. The status quo in recent years has given us the highest tax increase in Missouri history, cost hikes on our electric bills to provide subsidies for green energy, illegals draining Missouri resources, our farmland sold to foreign adversaries and policies that have led to the rise in violent crime. I served our country as a U.S. Marine during the war and returned home to serve our district as a first responder. I refuse to stand by and watch our citizens betrayed by the politicians who have chosen to serve the lobbyists and special interests over their constituents."[14]

Primary election competitiveness

This section contains data on state legislative primary election competitiveness in Missouri. These totals include data from all regularly-scheduled House and Senate elections. For more information about Ballotpedia's competitiveness analysis of state legislative elections, please click here.

Post-filing deadline analysis

The following analysis covers all state legislative districts up for election in Missouri in 2024. Information below was calculated on June 6, 2024, and may differ from information shown in the table above due to candidate replacements and withdrawals after that time.

There were 180 state legislative seats up for election in Missouri in 2024. Across those, 55 incumbents (22 Democrats and 33 Republicans) did not run for re-election. That was more than the average number of retirements in Missouri from 2010 to 2022 (53.0). In 2022, 49 incumbents (6 Democrats and 43 Republicans) did not run for re-election. Two state legislative seats were vacant.

Twenty-six incumbents out of the 123 running faced primary challengers. That was the third-most since 2010 after 2012 and 2022 which each had 35 incumbents who faced primary challengers.

There were 67 total contested primaries (with more than one candidate) - 19 Democratic and 48 Republican. The average number of contested primaries from 2010 to 2022 was 69.86. The year with the fewest primaries was 2014, which had 49 (16 Democratic and 33 Republican). 2010 and 2012 each had 86 contested primaries, the highest number during that span.

Missouri had a Republican trifecta, meaning the Republican Party controlled the governorship and both chambers of the state legislature. As of June 5, 2024, there were 23 Republican trifectas, 17 Democratic trifectas, and 10 divided governments where neither party held trifecta control.

2012 17 10 (59 percent) 7 (41 percent)
2010 17 10 (59 percent) 7 (41 percent)

Legislative referrals

See also: Legislative referral

A legislative referral, or legislatively referred ballot measure, is a ballot measure that appears on the ballot due to a vote of the state legislature. A legislative referral can be a constitutional amendment, state statute, or bond issue.

As of the 2024 election, a simple majority vote was required during one legislative session for the Missouri General Assembly to place a constitutional amendment on the ballot. That amounted to a minimum of 82 votes in the Missouri House of Representatives and 18 votes in the Missouri State Senate, assuming no vacancies. Amendments do not require the governor's signature to be referred to the ballot.

At the time of the 2024 election, Republicans held a 24-8 majority in the Senate and a 111-51 majority in the House. Democrats needed to win ten Senate seats and 31 House seats to be able to pass legislative referrals without Republican votes. Republicans needed to lose six Senate seats and 29 House seats to lose the same ability.

Process to become a candidate

DocumentIcon.jpg See statutes: Missouri Revised Statutes, Section 115.307

For state-recognized political party candidates

A political party candidate seeking placement on the primary ballot must file a declaration of candidacy with the appropriate election official by 5:00 p.m. on the last Tuesday in March immediately preceding the primary. The declaration of candidacy cannot be submitted prior to 8:00 a.m. on the last Tuesday in February immediately preceding the primary. The declaration must state the candidate's name, residential address, office being sought, and political party.[16][17]

Before filing a declaration of candidacy, a candidate must pay a filing fee to the treasurer of the state or county committee of the political party whose nomination he or she is seeking in the primary. Filing fees vary according to the office being sought and are as follows:[16][18]

Filing fees
Office Filing fee
Statewide offices (e.g., governor, secretary of state, etc.), United States Senator $500
United States Representative, State senator $300
State representative $150

A candidate must also file an affidavit with the Missouri Department of Revenue affirming that, to the best of his or her knowledge, the candidate is not delinquent in the payment of any state-owed taxes (e.g., income tax, property tax, etc.).[16][19]

A candidate is required to file for office in-person. In addition to completing the declaration of candidacy, a candidate must present proof of identity, a receipt for the payment of any filing fees, and a copy of the affidavit filed with the Missouri Department of Revenue. A candidate may file for office by certified mail if he or she is unable to appear in person due to a physical disability or is a member of the armed forces on active duty. Filing paperwork submitted via mail must be certified by a notary public.[16][20]

If a candidate is unable to pay the required filing fees, he or she may have the fee waived by filing a "Declaration of Inability to Pay" and a petition with his or her declaration of candidacy. If the candidate is filing for statewide office, the petition must be signed by a number of registered voters in the state equal to at least one-half of 1 percent of the total number of votes cast in the state for the office being sought at the last election in which a candidate ran for the office. If the candidate is filing for any other office, the petition must be signed by a number of registered voters in the district or political subdivision equal to at least 1 percent of the total number of votes cast for the office being sought at the last election in which a candidate ran for the office.[16][20]

Candidates for federal, statewide, and state legislative offices must file with the Missouri Secretary of State.[21]

For independent candidates

Like political party candidates, an independent candidate seeking placement on the general election ballot must file a declaration of candidacy and an affidavit affirming that he or she is not delinquent in the payment of any state-owed taxes. The candidate is required to file in person (with the same aforementioned exceptions). Independent candidates, however, are not liable for the payment of any filing fees.[22][23]

Independents must submit nominating petitions with their filing paperwork. Signature requirements vary according to the office being sought. For any statewide office, a nominating petition must be signed by at least 10,000 registered voters of the state. If the candidate seeks a district-level office, the petition must be signed by a number of registered voters in the district equal to at least 2 percent of the total number of votes cast at the last election for the office being sought, or 10,000 signatures, whichever is less.[22][23]

The candidate must file all required paperwork (including petitions) by 5:00 p.m. on the 15th Monday immediately preceding the general election for which the petition is submitted. Paperwork cannot be submitted prior to 8:00 a.m. on the day immediately following the general election next preceding the general election for which the petition is submitted.[22][24]

Candidates for federal, statewide, and state legislative offices must file with the Missouri Secretary of State.[21][22]
