A primary election is an election in which registered voters select a candidate that they believe should be a political party's candidate for elected office to run in the general election. They are also used to choose convention delegates and party leaders. Primaries are state-level and local-level elections that take place prior to a general election. Missouri utilizes an open primary system, in which registered voters do not have to be members of a party to vote in that party's primary.[3][4][5]

For information about which offices are nominated via primary election, see this article.

This page focuses on Missouri's 4th Congressional District Democratic primary. For more in-depth information on the district's Republican primary and the general election, see the following pages:

Submitted Biography:  "I am a small business owner in Nevada, Missouri and have worked as a real estate Broker since 1997. My wife Julia and I have five children and I've served on the local Board of Education for the past 16 years. I graduated from Westminster College in Fulton, MO is 1991 with a degree in Political Science. I have lived in Missouri's 4th District most of my life and, if elected, work hard for the people of our District."

Key Messages

To read this candidate's full survey responses, click here.

I believe in our public schools and will work hard to make sure they have the resources and support to be successful. Our public shools are the backbone of the communities and they give young people from all economic backgrounds the basic skills and knowledge they need to be successful. I will work hard to make sure our Career Technical Education schools in the district get the funding and support they need to continue to provide hands on training in fields like nursing, construction, agriculturen welding, culinary arts, business, engineering, and automotive.

We need more affordable housing in the district. In my job as a Realtor I see daily the lack of supply of good middle class affordable homes. We need to build more one level basic ranch style homes that people can afford. We need more of these homes for elderly Missourians in the District who have mobility problems and can't access washer and dryer in basement for example. I will work with our Government loan programs like FHA, USDA, and VA to create incentives for builders to build more homes like this and create jobs and increase the supply which will help our housing affordability issue.

We need to cool down the partisan rhetoric in the country and remember we are all Americans and are all in the same boat. Both Democrats and Republicans are concerned about the state of our Democracy but have different concerns about the causes. I will listen to both sides and do my best to represent people from both sides of the political aisle.

Post-filing deadline analysis

The following analysis covers all U.S. House districts up for election in Missouri in 2024. Information below was calculated on June 4, 2024, and may differ from information shown in the table above due to candidate replacements and withdrawals after that time.

Forty-three candidates ran for Missouri’s eight U.S. House districts, including 16 Democrats and 27 Republicans. That's an average of 5.38 candidates per district. That’s lower than the 7.13 candidates per district in 2022 but more than the 5.00 in 2020.

The 3rd Congressional District was the only open district. That’s one less than in 2022 when two seats were open. There were no open seats in 2020, 2018, 2016, and 2014.

Incumbent Rep. Blaine Luetkemeyer (R-03) did not run for re-election because he retired from public office.

Two congressional districts—the 1st and the 3rd—were tied for the most candidates running in a district in 2024. Four Democrats and five Republicans ran in the 1st Congressional District, and two Democrats and seven Republicans ran in the 3rd Congressional District.

Twelve primaries—six Democratic and six Republican—were contested in 2024. Between 2022 and 2014, there was an average of 11.6 contested primaries per year.

Five incumbents—one Democrat and four Republicans—were in contested primaries tin 2024, tying with 2018 and 2014 for the fewest this decade.

Candidates filed to run in the Republican and Democratic primaries in all eight districts, meaning no seats were guaranteed to either party.
