Republicans know they have to spend big to save Ken Paxton. They’re increasingly worried MAGA Inc. won’t throw down in time.

In private conversations over recent weeks, senior Hill Republicans and GOP officials have nudged President Donald Trump’s team to start spending more on the Texas Senate race before it’s too late, according to three people with direct knowledge of those conversations, who were granted anonymity to discuss them.

Those fears escalated after audio leaked of Paxton privately trashing Trump’s midterm convention, with some worrying it could impact whether MAGA Inc. continues spending after a current wave of GOP ad bookings run out Oct. 12.

A Trump operative told POLITICO that MAGA Inc. and its affiliates are expected to spend near $45 million on direct mail, TV, and digital advertising in Texas through Oct. 12, an increase from its previous $20 million to boost Paxton. But they said the team is still assessing how much more money to send in the final weeks, in consultation with Senate Republicans and their top super PAC, the Senate Leadership Fund.

The Trump operative, who like others in this article was granted anonymity to speak candidly, would not commit to any plans when asked by POLITICO.

With national Democrats starting to finally spend for their Senate nominee, James Talarico, after months of holding off, and as polling of the race tightens, Republicans expect the cost of salvaging Paxton’s campaign will only skyrocket. And, they’ve started to panic.

“It’s a five-alarm fire, no doubt,” one GOP senator said. “Can we put it out? I hope so.”

“This is a slow-moving car crash that we're witnessing right now,” a Republican strategist in the state said. “And there's a 75% chance that the ultimate result here will be catastrophic from a GOP Senate majority standpoint.”A fourth Republican, a national operative, spoke to the urgency factor: “While it’s money we shouldn’t have needed to spend, it needs to be spent now,” said a national GOP operative, describing the state as more winnable than North Carolina, Georgia and potentially Ohio.

Even with a massive war chest, Texas is turning into a huge money sink for the GOP that senators worry could hurt them in other tight races as they work to defend deep-red states and try to flip blue seats in Michigan and New Hampshire.

Trump himself nodded to some of the concerns at a rally just across the Texas border in Oklahoma Thursday night, saying those voters aren’t the ones he’s concerned about.

“We’re worried about Michigan. We’re worried about Texas,” he told the crowd. “We’re worried about a few states.”The president is scheduled to visit Texas again next week for a rally in San Antonio next Wednesday.

SLF poured another $60 million into Texas on Wednesday, bringing its total expenditure there to a record-breaking $131 million. With the MAGA Inc. money and additional GOP ad reservations, the race is already on track to top $200 million from outside Republican groups hoping to save Paxton. Paxton’s own campaign recently announced a $20 million ad buy — one of the largest single media investments in a Texas Senate race.

Some Republicans want MAGA Inc. to take over spending for Paxton in Texas in the final few weeks, so SLF can focus its resources elsewhere. MAGA Inc. could also funnel money into SLF’s recently established Texas PAC. But, according to two people with direct knowledge of that matter, that hasn’t happened.

“At some point I think the people spending that money are going to have to make hard choices and figure out where the money can have the biggest impact, and certainly Texas is the most expensive,” Sen. John Cornyn, who lost to Trump-backed Paxton in the primary, recently told POLITICO.

SLF Executive Director Alex Latcham indicated to POLITICO the group will keep spending in Texas: “Senate Leadership Fund’s investment through Texas PAC affirms our commitment to maintaining the Republican majority and defeating Far-Left liberals like James Talarico.”But Republicans’ money concerns have been complicated by Paxton himself. A growing number of GOP senators and top operatives have been stunned by what they described as unforced errors by the Texas Senate nominee.

For example, he crossed one of the brightest red lines with Trump, telling a group of donors that “everybody’s numbers dropped” after the president’s GOP convention in Dallas last month, according to the audio leak reported by The New York Times.

“There seems to be very little strategy there,” said another Republican senator, granted anonymity to candidly discuss the race. “Sometimes, I think [Paxton] wants to lose.”

The White House did not respond to a request for comment. Trump, while on his way to Texas to tour a motor facility on Thursday, told reporters he hadn’t talked to Paxton about his convention comments. Later, he told a crowd in Texas that “Ken Paxton was at my side more than anybody, and I have to always remember that because he can be a pain in the ass sometimes. I’ll be honest.”Sen. Ted Cruz (R-Texas) told reporters this week that he hadn’t seen the audio of Paxton trashing Trump’s convention. He acknowledged the stakes in his home state were high — and that the influx of cash is key.

“The reason that it is a serious race and a close race right now is that for several months the Democrats were massively outspending us,” he said, “and I am glad now that we are seeing money invested in communicating with the voters.”The White House has attempted to reassure concerned senators, with chief of staff Susie Wiles telling Senate Republicans this week that there will be enough money available for competitive races in the final stretch, according to two people with knowledge of the meeting.

GOP operatives in both Michigan and New Hampshire said they feel that some of the cash being shoveled toward Texas should be going to their states instead. Most polls show Republicans running narrowly behind or neck and neck in both states, even though they hold a spending advantage on the airwaves there.

“We’re focusing so much on ‘we’ve got to put this money into Texas.’ Why? We’ve never had a problem in Texas. Let’s focus on taking back a seat we haven’t had in years,” said an ally of former Sen. John E. Sununu, who’s in a tight race against Democratic Rep. Chris Pappas. “There are real chances in Michigan and New Hampshire,” said the person, who was granted anonymity to speak candidly about the dynamics. Sununu’s campaign did not respond to a request for comment.

Latcham, who heads SLF, said that “Texas PAC is a dedicated effort that will not take resources from our other ongoing investments across the Senate map.”Recent polling still shows the Texas Senate race with a razor-thin margin. Most public polling over the past two months shows Talarico with an edge, though Paxton’s campaign released an internal poll Tuesday that shows Paxton leading by three points among likely voters, 48% to 45%.

“I don't think the needle has moved in the last month,” said one Texas Republican elected official, granted anonymity to speak frankly. “Unless it's the worst polling that's ever been done in political history, all this spend hasn't changed anything, and I think people have made their mind up.
