Who are you? Tell us about yourself.

A 4th generation Missourian, I grew up throughout the St. Louis area, including my formative years in a doublewide at a trailer park. After attending multiple school districts, I was able to attend college, working multiple jobs throughout.

After graduation, I made the best decision of my life and enlisted in the US Army; later earning a commission as a Field Artillery officer. I deployed to Afghanistan during the surge of 2010-11 as a Mortar Platoon. Leader, earning a Bronze Star. I deployed again to Afghanistan with the 101st Airborne Div.

After the second deployment, I utilized the GI Bill to earn my Masters in Public Administration from George Washington University. Going to school at night, and learned policy firsthand by working on Veterans Administration, budgetary, defense, and international affairs issues in the US Senate and House.

Later, my focus was on national defense transportation issues for over three years at Scott Air Force Base. Most recently I am the Director of Government Affairs for a non-profit organization with lead remediation from water, access to clean drinking water, and plumbing safety codes as primary tenets.

I'm married to an incredible woman, Caitlin, and dad of two incredible girls, Evelyn Rosemary (4) and Kennedy Providence (1).

Please list below 3 key messages of your campaign. What are the main points you want voters to remember about your goals for your time in office?

I'm a democrat from a trailer park, who went to war twice, who supports a woman's right to choose, stands with labor, and goes where people feel forgotten.
The state where the first kindergarten was started is now nearly dead least in teacher pay and resources...with some schools going only 4 days a week and others requesting teachers serve as bus drivers. We are near the bottom of every educational and crime category. There is only one smoking gun...20 years of inept GOP rule. They're not bad people, just very bad at their jobs.
We're fearing the wrong things. Our towns die because of changing job demands and technological influences, not immigration. The best way for Missouri to address the crime rate is by making certain Missouri Highway Patrol Officers stay in Missouri...and not staring into Mexico from the Texas border for purposes of fear mongering and vanity exercises.

What areas of public policy are you personally passionate about?

- Instituting a statewide childcare initiative to lower costs

- Fully resourcing public schools, teachers, administrators, and staff
- Ensure only public schools receive public funds
- Restrict school vouchers
- Protect unions by thwarting Right to Work efforts
- Protect IVF and women's healthcare

- Protect and institute new partnerships with Missouri agriculture and public/state entities to lead the nation in farming partnerships

What qualities does this office possess that makes it a unique and important part of the state government and legal system?

Building the best loan programs for Missouri farmers, protecting retirement funds, growing the MOST 529 (education) plan.

Who do you look up to? Whose example would you like to follow, and why?

President John Kennedy and Attorney General Robert Kennedy have been pillars for me since childhood.

I hold President Jimmy Carter in the highest esteem. I've been fortunate to have met him twice. The first time days after I commissioned in the Army. The second, as I was separating from active duty. He is the embodiment of a public servant.

What characteristics or principles are most important for an elected official?

Integrity, discernment, adaptability.

What is the first historical event that happened in your lifetime that you remember? How old were you at the time?

The Berlin Wall falling...I was 7 years old and vividly remember my grandfather saying, "Marky, shhhh." We watched the nightly news report and hammers wailing on the wall. I didn't fully understand what it meant but knew it was an immense thing.

What was your very first job? How long did you have it?

I worked at McDonalds...workers permit and all in 1997 making a staggering $4.75 per hour.

What responsibilities of this office do you personally consider the most important?

As a veteran, defending the taxpayer's money from misuse, misspending, abuse, and incompetence.

Are there any little-known powers or responsibilities held by this office that you believe more people should be aware of?

Returning military medals and awards to rightful owners or their families.

What organizations or individuals have endorsed your campaign?

VoteVets, New Politics, AFL-CIO

What are your views on financial transparency and government accountability?

Simple, easy, understandable transparency of how Missouri spends its money is integral to public and taxpayer confidence and engagement.

Campaign website

Osmack’s campaign website stated the following:

“	WHAT MARK STANDS FOR ✅ CHAMPIONING MISSOURI FAMILIES As a husband and father of two young daughters, Mark understands the demands and costs of raising a family. He will make Missouri the place families want to stay in and move to rather than leave. 🛡️ PROTECTING FUNDING FOR MISSOURI RETIREES AND FARMERS Missouri government has played fast and loose with benefits earned by our retired citizens and enhancements for Missouri farmers to thrive. As a 4th generation Missourian, Mark will not bend or yield to the games of Jefferson City threatening to end these benefits. 💲INCREASING RESOURCES FOR FIRST RESPONDERS AND TEACHERS As a Missourian who attended public schools and as a soldier deployed to war twice, Mark personally understands the critical need for supporting those who protect and educate us…because he’s lived it ^[2]	”
