Texas politics isn't for the faint of heart, and Ken Paxton is basically the poster child for political survival. If you've been watching the 2026 Republican primary for U.S. Senate, you know the narrative. The established donors—the guys with the deepest pockets in Dallas and Houston—are mostly backing John Cornyn. They see Cornyn as the safe, reliable hand. They see Paxton as a walking lightning rod of legal drama.
But here’s what most people get wrong about Texas elections. Money matters, but who gives it matters more. John Cornyn is sitting on a mountain of cash, raising over $9 million in the first quarter of 2026 alone. Paxton? He brought in about $2 million. On paper, it looks like a blowout. In reality, Paxton is betting on a "Patriot" army of small-dollar donors to do what big checks couldn't.
The Massive Gap in the War Chests
Let’s look at the numbers because they’re staggering. As of the end of March 2026, John Cornyn had roughly $8.2 million in the bank. Paxton had about $2.6 million. That’s a three-to-one advantage for the incumbent. If this were a traditional race from twenty years ago, we'd say it’s over.
Cornyn’s support comes from the traditional Republican heavyweights. We're talking about names like George W. Bush, Karl Rove, and former House Speaker Joe Straus. These are the titans of the "Old Texas" GOP. They represent the business interests, the oil executives, and the institutional donors who want stability.
Paxton is operating in a different world. While he lost some big-name backers after his impeachment trial and various legal battles, he’s replaced them with a grassroots machine. His campaign is powered by "Paxton’s Patriots," a network of individuals who give $25, $50, or $100 at a time. It’s the Trump model of fundraising, and it’s surprisingly effective at keeping a candidate alive when the establishment tries to starve them out.
Why Big Donors Aren't the Kingmakers Anymore
Honestly, the era where five billionaires could pick the Texas Senator is fading. You can buy all the TV ads you want, but if the primary voters don't trust the messenger, that money is basically just noise.
Cornyn has spent nearly $24 million this cycle. Think about that. He’s spent a fortune, yet the March primary ended in a virtual dead heat. Cornyn took 42% and Paxton took 41%. If money was the only factor, Cornyn should have won that outright without a runoff.
The reason he didn't? Paxton has something money can’t easily buy: intense brand loyalty. To a specific segment of the Texas GOP, Paxton is a martyr. Every legal filing against him and every donor who walks away just reinforces the idea that he’s the "outsider" fighting the "system."
- Cornyn's Strength: Massive TV buys, institutional backing, and "get out the vote" infrastructure.
- Paxton's Strength: High-intensity supporters, social media dominance, and a "fighter" persona.
The Outside Money Influence
We can’t talk about this race without mentioning the Super PACs. This is where the real "big donor" war is happening. Groups like Texans for a Conservative Majority have poured over $26 million into supporting Cornyn. On the other side, Paxton has the Lone Star Liberty PAC.
The spending gap here is even wider. Pro-Cornyn groups have outspent pro-Paxton groups nearly ten to one. But here is the kicker: negative ads have a point of diminishing returns. After the thousandth ad telling you Ken Paxton is under investigation, voters either believe it or they’ve decided they don't care. Paxton’s base has clearly decided they don't care.
The Runoff Reality
The runoff on May 26 is a different beast entirely. Runoffs are about turnout, not persuasion. You aren't trying to convince undecided voters anymore; you're trying to make sure your people actually show up on a random Tuesday in May.
Paxton’s supporters are, quite frankly, more obsessed. They’re the ones who show up to every rally and post on X (formerly Twitter) all day. Cornyn’s supporters are often more "passive" Republicans—people who like his record but aren't necessarily going to crawl through broken glass to vote for him in a runoff.
Can He Win Without the Billionaires?
The short answer is yes. We’ve seen it happen. Look at how many establishment-backed candidates lost to "insurgent" types in the last few Texas primary cycles. Paxton himself survived an impeachment trial that many thought would be his political death warrant.
If Paxton wins, it will be because he proved that a populist base is more powerful than a corporate donor list. It would signal a permanent shift in the Texas GOP away from the Bush-era "country club" Republicans and toward a more combative, grassroots-led party.
However, don't count Cornyn out. He’s a savvy operator with a lot of friends in low (and high) places. He’s using his financial advantage to blanket the state in negative ads, hoping to depress Paxton’s turnout.
If you're following this race, watch the "cash on hand" in the final weeks, but keep a closer eye on the early voting numbers in the rural counties. That’s where Paxton’s "Patriots" live, and if they show up in force, all the billionaire money in the world won't save the incumbent.
