United States Senator Thom Tillis has voiced sharp criticism regarding former President Donald Trump’s influence on the Texas Republican primary. In a recent television appearance, the North Carolina Republican suggested that the former president’s decision to intervene in the race has jeopardized a Senate seat that would otherwise be secure. By backing a controversial candidate over a long-standing incumbent, Tillis argues the party has created an unnecessary financial and political burden heading into the general election.
What happened
During a Sunday interview on CNN’s “State of the Union,” Senator Thom Tillis characterized Trump’s support for Texas Attorney General Ken Paxton as a “colossal mistake.” Tillis, who has frequently deviated from the party line regarding the former president, argued that the decision to prioritize Paxton over incumbent Senator John Cornyn was a strategic “unforced error.”
Paxton successfully defeated Cornyn in the May primary after receiving a late-stage endorsement from Trump. Tillis pointed out that the GOP is now forced to invest massive amounts of capital—potentially reaching hundreds of millions of dollars—to defend the seat in Texas. According to Tillis, this level of spending would have been unnecessary had Cornyn, a four-term veteran of the Senate, secured the nomination.
Context
The primary battle in Texas was more than just a local contest; it served as a litmus test for Trump’s influence over the Republican base. Trump’s endorsement of Paxton was driven largely by loyalty. While Paxton has remained a vocal supporter of the “Make America Great Again” movement, Cornyn had publicly suggested that the GOP should distance itself from Trump following the 2024 presidential campaign. In response, Trump labeled Cornyn “VERY disloyal” on social media, urging Texas voters to reject him.
However, Paxton enters the general election with significant political and personal baggage. Although he was acquitted in a 2023 impeachment trial involving corruption allegations and saw a felony securities fraud case dismissed after a pretrial agreement, his reputation remains a point of contention. Furthermore, his personal life has come under scrutiny following a July 2025 divorce filing by his wife, Angela Paxton, who cited biblical grounds involving adultery.
On the other side of the aisle, Democratic candidate James Talarico has emerged as a formidable challenger. A state legislator and pastor, Talarico has gained traction with a platform focused on populism and reconciliation. If Talarico is successful, he would be the first Democrat to win a statewide office in Texas in three decades.
Why it matters
The friction between Tillis and the Trump-aligned wing of the party highlights a deepening divide within the GOP. Tillis has positioned himself as a defender of traditional conservative alliances and institutional stability. His criticism of the Texas primary follows previous instances where he broke ranks, such as his vocal defense of the NATO alliance and his calls for the resignation of former Homeland Security Secretary Kristi Noem following controversial agency actions.
For the Republican Party, the stakes in Texas are exceptionally high. The state has long been a reliable stronghold for the GOP, but the necessity of defending it with significant resources may drain funds from other competitive battlegrounds. If Paxton’s legal and personal history alienates moderate voters, the “unforced error” Tillis described could potentially shift the balance of power in the Senate, proving that ideological loyalty tests can sometimes carry a heavy electoral price.
