Senator Thom Tillis of North Carolina used a CNN appearance Sunday to deliver one of the sharpest intra-party criticisms of Trump's primary intervention strategy: backing Texas Attorney General Ken Paxton over four-term incumbent John Cornyn in the state's Senate Republican primary. Tillis called the endorsement a 'colossal mistake' and an 'unforced error' that has transformed a safe GOP seat into an expensive general-election fight. The math is straightforward. Cornyn was a known quantity — a veteran senator with high name recognition and no serious electoral vulnerabilities in deep-red Texas. Paxton won the primary but carries a scandal portfolio that reads like a stress test: a 2023 impeachment (acquitted in the Texas Senate), a felony securities fraud indictment (dismissed via pretrial diversion in 2024), and a July 2025 divorce filing from his wife of 38 years citing adultery 'on biblical grounds.' Each line is a Democratic opposition ad waiting to be cut. Trump's logic was loyalty. He endorsed Paxton days before the vote, calling Cornyn 'VERY disloyal' for suggesting during the 2024 campaign that Republicans should move on from Trump. The endorsement landed and Paxton defeated Cornyn, but the instrument of that victory — a loyalty purge of a safe incumbent — is precisely what Tillis argues has opened the door to Democrat James Talarico in November. Talarico presents a specific kind of threat. A pastor and state legislator running on what's being described as a 'peace and populism' message, he occupies cultural terrain that complicates the standard Texas partisan map. If he wins, he would become the first Democrat to win statewide office in Texas in more than three decades — a symbolic earthquake with real structural implications for future cycles. Tillis is not a random critic. He's a retiring senator who has built a late-career pattern of breaking with Trump on high-profile issues: defending NATO after Trump floated withdrawal, calling for Kristi Noem's resignation after immigration agents killed two US citizens in Minneapolis, and voting Thursday for a Democrat-led war powers resolution to end the US war with Iran (which failed 49-50). His criticisms land differently precisely because he's leaving — there's no reelection calculus to discount. The deeper structural question is whether Trump's primary intervention model — rewarding personal loyalty over electoral viability — is sustainable when it converts safe seats into competitive races. Texas should not be a battleground for Republicans, but Tillis estimates the party will now spend 'tens or hundreds of millions of dollars' defending it. Every dollar spent in Texas is a dollar not spent in genuinely competitive states. The November general election will be the referendum. If Paxton holds Texas comfortably, Trump's loyalty-first model survives another cycle. If Talarico makes it close or wins, the Tillis critique becomes the autopsy.
