Trump’s Biggest Endorsement May Trigger Painful Primary Memories For Republicans

President Donald Trump made his most high-stakes primary endorsement Tuesday, sidestepping the Republican incumbent and establishment favorite. Although MAGA diehards cheered the president’s 11th-hour pick, Republican operatives may be experiencing primary déjà vu.

Trump finally put his thumb on the scale in the Texas Senate race, ultimately endorsing Texas Attorney General Ken Paxton over incubment Republican Sen. John Cornyn just one week before the GOP runoff. In his announcement, Trump commended Paxton as a MAGA ally, praising his support for terminating the filibuster and passing the SAVE America Act.

As for Cornyn, the president criticized that “he was not supportive of [Trump] when times were tough.”

Trump supporters embraced Paxton with open arms, but the GOP is likely replaying the tough choices the party had to make during the 2022 primaries. (RELATED: EXCLUSIVE: Texas Senate Hopeful Ken Paxton Taking Tons Of Democrat-Linked Trial Lawyer Cash, Data Shows)

Democratic Senate nominee James Talarico is currently polling ahead of both Republicans. That being said, Cornyn would have a slight advantage against Talarico compared to Paxton in the general election. According to RealClearPolling averages, Talarico has a slim 0.5% advantage over Cornyn compared to a 1.5% advantage over Paxton.

Paxton’s fundraising capacity is also comparably weaker than Cornyn’s. The advantage of being the establishment candidate is that you have the establishment’s resources at your disposal. This includes the National Republican Senatorial Committee (NRSC) and the Senate Leadership Fund (SLF), both of which operate at the behest of the Senate GOP.

In the first quarter of 2026, Cornyn raised roughly $9 million while Paxton brought in $2.2 million. Throughout the whole cycle, Cornyn has raised a jaw-dropping $26.5 million compared to Paxton’s $13.5 million.

“The endorsement would’ve made a difference two weeks ago,” one Texas Republican operative told Politico. “Cornyn has the more sophisticated GOTV operation. Paxton has a strong base, but he already hit his ceiling.”

Talarico has also dwarfed Paxton’s fundraising numbers, bringing in $27 million in the first quarter of 2026 compared to Paxton’s $2.2 million.

Republican Alaska Sen. Lisa Murkowski expressed concern about Trump’s endorsement of Paxton, arguing it would make it harder for the GOP to hold onto the seat.

“Based on the numbers that I’ve seen, yeah,” Murkowski said, according to a report in The Hill on Wednesday. “How does that help strengthen the president’s hand when we lose a state like Texas?”

The bottom line is Paxton appears to be a tougher sell for Texans, and the massive fundraising gap puts Republicans in a tougher position. Not only will they have to spend more money on the race to compensate for this fundraising gap, but they will also have to spend more money on the race trying to convince Texans to vote for Trump’s pick.

As a result, resources will be diverted from competitive races across the country in an effort to secure a safe red Senate seat. And at the time of this writing, it’s not obvious Republicans are going to hold onto it. (RELATED: Social Media Posts And A Spanish Campaign Ad Expose John Cornyn’s History Of Support For Amnesty)

The GOP was faced with a similar scenario back in 2022 when two of the most-watched races were in Arizona and Ohio. Thiel-ally and venture capitalist Blake Masters were pushing along in the swing state of Arizona while then-Republican candidate JD Vance was underperforming in the contentious Ohio race.

Republicans made the choice to pivot and redirect their efforts to getting Vance elected to a safer seat, siphoning resources from Masters’ more competitive race. The most glaring example leading up to the 2022 election was when the SLF, the campaign arm aligned with then-Leader Mitch McConnell, cancelled nearly $10 million in TV ads for Masters in Arizona to “concentrate [its] efforts” on other pickup opportunities like Vance’s race in Ohio.

Masters went on to lose the race by 4.9%.

With the 2026 elections fast approaching, Republicans may once again find themselves helping a candidate, in this case Paxton, win a safe seat while more contentious races go unattended. (RELATED: ‘New Leadership’: Blake Masters Says McConnell Deserves The Boot)

Some of these races include Ohio and Maine, both of which are rated toss-up races, according to the Cook Political Report. North Carolina’s seat is currently held by retiring Republican Sen. Thom Tillis, but is predicted to potentially flip blue. Michigan’s Senate seat is also a potential pickup opportunity for Republicans and Georgia was at one point considered within reach.

All of these races would benefit from a strategic push on behalf of Senate campaign operatives. But because of Trump’s latest endorsement, they might not get it.
