This is only our beginning.

Thank you all for an unbelievable experience. I had no idea where this was going to lead… but I couldn’t have imagined the community we’d build together.

This is not the last you’ll hear from me. Stay tuned.

I love you all 💙☺️

Congratulations, Bethany Mann, on your victory to represent Missouri's 3rd District this November.

To those who voted for me, thank you so much. This campaign has been an incredible experience. Meeting, talking, and campaigning with you has been the experience of a lifetime.

Moving forward, the end goal remains the same: flip MO-03 blue. Take the seat away from an enabler of fascism and oligarchy and win it for someone accountable to and who will fight for the people of Missouri.

Today, Missouri defeated Amendments 4 & 5 and continues to prove that while our opponents have the money, we have the many.

The power of the people is greater than the people in power. Show them your power. 👊

Likely the best endorsement we could have received 🥹 Thank you so much, Jackie. So blessed to have met you 🙏 #missouri #stcharlesmo #columbiamo #stpetersmo #wentzvillemo

Happy election day, Missouri!

So many of you have checked out our website and social media pages this week and throughout July.

Thank you so much for considering me for Missouri's 3rd District. I hope I've earned your vote today, and I'm so looking forward to earning your vote in November.

Whether you're voting for me today or not, I hope you'll make time to have your voice heard at the ballot box.

Polls close at 7:00 p.m., let's do this 🤘

I understand if you've never been political, but life is political.

Who lives and who dies is political.

Who lives and who thrives is political.

18 American service members and 1,000-3,000 Iranian civilians have lost their lives in a completely avoidable war with Iran. Another 624 American service members have been injured so far.

Millions of lives are at risk from the cuts to USAID.

At least 74,000, including over 20,000 children, killed in Gaza and the West Bank.

56 people died in ICE custody, that's nearly 1 death every 10 days for this administration.

7 people outright killed and many more shot by federal agents during over-the-top immigration enforcement operations.

We can disagree on so much, but I hope our political future includes agreeing on principled positions that promote well-being while limiting pain and suffering whenever possible.

Money is pouring into Missouri to convince you to vote against your best interests.

If Amendment 5 passes, your costs will go up. According to the Missouri Budget Project, 80% of Missourians would have a net tax increase after accounting for the rise in sales and other regressive taxes.

If Amendment 4 passes, citizens would lose their power to directly affect our state's constitution and open our state up to more dark money attacks. As Michael A. Wolff, former Chief Justice of the Supreme Court of Missouri, put it, "Opponents of a citizen-initiated proposal could find one congressional district where polling indicates the voters would be receptive to a negative campaign and bombard that district with negative messages."

In my recent interview with The St. Louis Podcast, we discussed the importance of voting NO on Amendment 5.

"What a great plan to make life so overwhelming that you can't pay attention to the news because you have to work two jobs, you got three kids, you gotta take them to soccer practice. Then, you're tired, and you can't even pay attention to the TV show you're watching because you're too exhausted. And then they gaslight us because they know that we're all feeling like that, that we're overwhelmed, that we can't pay attention to all of this."

Welcome to a special election edition of FACT or FICTION 📝

These are 5 common claims about elections and whether they're true (or made up by billionaires).

Make a plan to vote August 4th if you're tired of money controlling our politics. Vote for Tommy Holstein 🤘

Honored to be recognized as a 2026 Gun Sense Candidate by @momsdemand . As a dad, I want my daughter to grow up safe. As a Missourian, I respect the 2nd amendment.

We can fight for both.

Vote August 4th 🗳�️

🚨POP UP RALLY - TODAY, AUG 1🚨

We have a last-minute pop-up rally at Old Towne Park in St Peters, Missouri, at 11am.

We’ll have speakers and food, and we’ll spend some time in the community after.

We’re doing everything we can before the primary election on August 4th. If you’re in the area, we’d love to see you.

A few weeks ago, Janie and her two girls got on a one-way flight to Mexico.

Because it was the only way to keep her family together.

Her husband Alejandro paid taxes. He went to church. He worked two jobs.

In October, ICE arrested him on his way to work.

Five months later, they walked him across the border.

Before she left, Janie asked me to send one important message: Go meet your neighbor.

Want to hear her story? Check out the full 45-min interview on YouTube.

Your Ameren bill is going up so a data center can move in down the road. That’s the deal Big Tech is offering Missouri, and nobody asked us first.

They’re draining our water, spiking our utility bills, and heating up the land around them. AI is being handed to our kids before anyone stopped to ask what it’s doing to them. And Meta paid less than 4% in taxes last year while skipping out on $14 billion that could’ve gone to veterans, housing, and food assistance.

Build the future. Just don’t build it on top of us.

I don’t take a dime of corporate PAC money, so I can say all of this out loud.

Swipe through, then tell me what you’re seeing in your own community.

We're hosting a RALLY tomorrow (8/1)! 🤘

If you 🫵 want to see Tommy take on Bob Onder in November, we need you to act NOW. The primary is only step one, and we can only cross the finish line with your help.

Anyone who donates $25 or more will receive a campaign button, sticker, and bumper magnet. Folks who donate more than $50 will receive a tote bag. Anyone who donates $100 or more will get a shoutout from Tommy at the event, all of the mentioned swag, PLUS a campaign t-shirt. 💙

We're also doing a school supply drive benefiting Youth In Need, a non-profit here in Saint Charles. Bring any school supplies for all ages, cleaning supplies, and toiletries. Youth In Need helps children facing housing insecurity. Please help us make an impact for this organization! 📚✏️✂️ #holsteinformo #rally #tommyholstein

Here’s the plan: vote Tuesday, Aug 4. And get 5 friends to do the same. One vote is one vote. Five friends is six.

A text from you beats every ad in the world. People show up when someone they trust asks them to. This week, that’s you.

Don’t overthink what to say. Steal this 👇

“Hey! The primary election is on Tuesday. Polls are open until 7pm. I’m voting for Tommy Holstein for Congress. What about you?”

5 friends. 5 days. Go. 🗳️

Huge thank you to Mitchell Kaminski and KMIZ for highlighting Missouri's 3rd District and interviewing both me and Bethany Mann.

I encourage everyone to listen or read both interviews (links in the comments).

As I've met with so many voters across MO-03, some things have been made incredibly clear to me and strengthened my resolve to represent Missouri in Washington D.C.:
• Missourians are tired of the richest amongst us getting richer while our own standard of living flatlines or even declines.
• Missourians are tired of the increased cost of healthcare, groceries, and homes.
• Missourians are tired of big tech and mega corporations looting our communities of natural resources.
• Missourians are tired of their elected leaders selling our interests to the highest bidders.

These frustrations affect all of us. How we respond affects all of us.

🤘 Let's make our voices heard at the ballot box. Get your vote in by August 4th.

We're hosting a virtual town hall TOMORROW @ 7:00PM! Join us on Twitch or YouTube to listen and ask your questions 🤘

We're only a week away from our primary, folks. This is the time to buckle down, get serious, and ask your candidates hard questions. Let me earn your votes.

MO-03 will be a highly contested district this November. Our campaign, our primary opponents, and the Republican challenging Onder all agree that this seat is up for grabs.

This seat can continue to enable or, if we flip it, can hold the administration accountable.

📖👀→ https://abc17news.com/politics/your-voice-your-vote/2026/07/24/democrats-look-to-flip-missouris-3rd-district-as-republican-challenger-targets-onders-voting-record/

Amendment 5 is pressing issue—they're going to use it to take even more of your paycheck and give their rich friends tax breaks. Amendment 4 is how they're going to take our voice away.

We passed abortion protections, guaranteed sick leave, and raised the minimum wage all through ballot initiatives.

They're already trying to legislate our choices away—don't make it easier for them to halt progress.

Don't let them take any more from us. 🙏

What you need to vote in Missouri

Here's what you need to know before you go to vote this primary season.

Ensure you're registered (in 2026, trust me, you'll want to double-check).
Bring your photo ID (necessary for Missouri). Acceptable voter IDs include non-expired Missouri driver's license, non-expired Missouri state ID card, non-expired US passport, non-expired military ID, or another non-expired photo ID issued by the United States or Missouri. Student IDs DO NOT COUNT.
Pick a ballot. For primary elections in Missouri, voters must choose a single party's ballot or receive an issues-only ballot. If I've earned your vote, you'll need to request a Democratic Party primary ballot.

Important notes:

You do not need to bring a registration card or proof of address to vote, just bring your valid photo ID to your polling place on August 4th or to your local Election Authority office for early voting.
You do not need to register with any political party to vote in their primary election or to vote on the very important ballot initiatives. Simply request the ballot you want from the election judge (Democratic Party, Republican Party, Libertarian Party, Constitution Party, or the issues-only ballot).
You have the right to a free voter ID. The Missouri Department of Revenue will provide you with one non-driver's license photo ID for voting purposes. Visit https://dor.mo.gov/ or call (573)-526-8683 to learn more.
You have the right to fill out a provisional ballot. If you lost your ID, request a provisional ballot when you go to vote.

Learn more about my thoughts on the issues you'll see on the primary ballot:
