Both of my opponents are funded with hundreds of thousands of dollars from the gambling industry. We shouldn’t try to fix our budget crisis by getting people hooked on slots or putting them in areas where kids can get to them.

I’m honored to receive an A Rating from the NRA Political Victory Fund. The Second Amendment isn't about politics, it's about protecting our rights. I’m a lifetime member of the NRA, and throughout my time in the Missouri House, I've stood with gun owners, hunters, sportsmen, and families who believe our freedoms are worth defending. As an engineer, I don't make excuses, I solve problems. And I'll continue fighting for the conservative values that matter to the people of Senate District 16.

I can’t be bought. Why are my opponents receiving BIG money from illegal gambling device companies, casinos, and trial lawyers? Because I won’t blindly do their bidding. Let’s send a conservative engineer to the state senate, not another lawyer or politician.

Engineers don’t make excuses, we solve problems. That’s exactly what I’ll do in the State Senate.

Some people grew up wanting to be lawyers and politicians. I didn’t. Let’s send a conservative engineer to the state senate on Tuesday, August 4th.

We only get one shot to defeat the lobbyists and special interests who are doing all they can to buy this senate seat. Let’s send a message and elect a conservative engineer, who can’t be bought, to the State Senate.

Figures cover domestic political ads paid in dollars, from 4 May 2026. Spend is the sum of Meta’s range midpoints; impressions above one million are reported as “1M+”, so impression figures are floors. Each ad counts in the week its delivery started, with its lifetime spend at our last pull; ads still running before the vote are counted as of 31 October 2026.
