The 2026 midterm primaries are not a normal election cycle. They are a hostile takeover.
President Donald Trump has endorsed over 200 candidates across Senate, House, and state legislative races — the most aggressive primary intervention by a sitting president in modern history. His targets: Republican incumbents who crossed him. His weapon: a $389 million war chest and a base that treats his endorsement as a loyalty oath.
The first results are in from Super Tuesday on March 3, and they confirm what Washington feared: the Republican Party is eating itself alive.
The Crenshaw Shock
The night's biggest casualty was Rep. Dan Crenshaw of Texas, a decorated Navy SEAL and one-time conservative media darling. He lost his primary to Trump-aligned state Rep. Steve Toth, 56% to 41%. It wasn't close.
Crenshaw's crime? Calling January 6th participants "domestic terrorists" and questioning Trump's claims about the 2020 election. In 2026, that's a political death sentence in a Republican primary.
- **200+** Trump endorsements issued for 2026 races
- **435** House seats and **35** Senate seats up for grabs
- **Dan Crenshaw** became the first major incumbent toppled
- **May 26** Texas Senate runoff: Cornyn vs. Paxton
- **Nov 3, 2026** General election day
The Texas Senate Showdown
The marquee race of the night — the Texas Senate primary — ended without a winner. Four-term incumbent John Cornyn scraped 42% against Attorney General Ken Paxton at 41%, forcing a May 26 runoff that will define the soul of the Republican Party.
Cornyn, once the second-most powerful Republican in the Senate, now faces a grueling two-month sprint against a man he publicly called "flawed, self-centered, and shameless." Paxton, who was acquitted of impeachment charges in 2023, has Trump's implicit support and the grassroots energy that comes with it.
- 4-term incumbent senator
- $5.4M raised in Q4 2025
- Backed by Senate Leadership Fund
- Warns Paxton win means "Election Day massacre"
- Texas Attorney General
- $1.1M raised in Q4 2025
- Trump's implicit endorsement
- Grassroots MAGA base energy
Notably, Trump did not formally endorse in this race — a strategic ambiguity that lets him claim the winner regardless of outcome. But the message to Cornyn was unmistakable: no Republican is safe.
Follow the Money
The financial asymmetry tells the real story. Trump's political apparatus — spanning Save America, MAGA Inc., and joint fundraising committees — entered 2026 with a combined $389 million war chest. MAGA Inc. alone holds $304 million.
The establishment's defense fund, the Senate Leadership Fund aligned with Majority Leader John Thune, has spent $110 million on TV ads in just the first three months of 2026. But they are playing defense on multiple fronts simultaneously.
KEY STAT: The RNC ended 2025 with $95 million cash on hand. The DNC reported just $14 million — and $17 million in debt. Democrats are entering the most consequential midterm in a generation broke.
The Hit List
Trump's "retribution" campaign goes beyond Texas. Here are the primary targets across the country:
| Target | State | Offense | Trump's Pick | Status |
|---|---|---|---|---|
| John Cornyn | Texas | Past Trump criticism | Ken Paxton (implicit) | Runoff May 26 |
| Bill Cassidy | Louisiana | Voted to convict (2021) | Julia Letlow | Primary ahead |
| Susan Collins | Maine | Voted to convict (2021) | TBD challenger | "Top-tier" threat |
| Dan Crenshaw | Texas CD-2 | Called J6 "terrorism" | Steve Toth | Defeated |
| Spencer Deery | Indiana State | Blocked Trump agenda | Paula Copenhaver | Primary ahead |
The pattern is consistent: any Republican who broke with Trump on January 6th, impeachment, or his legislative agenda faces a primary challenger bankrolled by the MAGA machine.
The Timeline: How We Got Here
The Democratic Gambit
Democrats are watching the Republican civil war with cautious optimism — and a nearly empty bank account.
The DSCC's strategy is straightforward: let Trump nominate "flawed" candidates in primaries, then beat them in November. It worked in 2022 with candidates like Herschel Walker and Dr. Oz. The party is focusing resources on three "flippable" seats: Maine (Collins), North Carolina (open seat with Thom Tillis retiring), and Texas.
In Texas, Democrat James Talarico is positioning himself as a moderate alternative, betting that suburban voters exhausted by MAGA infighting will cross over. In North Carolina, former Governor Roy Cooper represents the Democrats' strongest recruit.
But there is a structural problem Democrats cannot ignore.
The Thune Dilemma
Senate Majority Leader John Thune is caught in the most impossible position in Washington. He needs Trump's base to hold the Senate majority. He also needs incumbents like Cornyn and Collins to survive — because their replacements might be too extreme to win general elections.
Thune has pledged "full support" for incumbents while simultaneously admitting he "cannot guarantee" passage of Trump's SAVE America Act, the voter ID and citizenship verification bill that Trump has made the litmus test of loyalty.
Trump's threat is explicit: he will veto all legislation until the Senate passes the SAVE America Act. That sets up a potential summer of government shutdowns — in a midterm year.
What Happens Next
The Texas Senate runoff on May 26 is now the single most important race in American politics. If Paxton defeats Cornyn, it will signal the complete extinction of the Bush-era Republican establishment — and embolden Trump-aligned challengers in every remaining primary.
If Cornyn survives, the establishment can argue that Trump's influence has limits, even in deep-red Texas.
Either way, analyst Susan Glasser's description of Trump's 2026 strategy seems apt: an "octopus-like" effort to simultaneously rewrite election maps, purge dissenters, and position loyalists for the 2028 succession battle.
This is not just a midterm election. It is a party realignment happening in real time, funded by hundreds of millions of dollars, with the future of American governance as the stakes.
The primaries run through September 15. The real war is just beginning.
