Texas GOP Primary Highlights Internal Party Struggles

At a crowded campaign event in Dallas on May 18, 2026, Diane Benjamin’s hat stood out amidst the supporters gathered for Texas Attorney General Ken Paxton. Held at an old-school barbeque joint filled with music and the scent of smoked meats, this rally attracted voters from Katy, a diverse suburb of Houston. Among them were Ricardo Vidaurre and his wife, who were enthusiastic participants, dancing to familiar tunes like ‘YMCA’. Vidaurre expressed his admiration for Paxton, calling him courageous.

Just a day before, President Trump endorsed Paxton for the U.S. Senate, marking a costly primary battle in history. The incumbent, Sen. John Cornyn, known for his establishment roots in the party, now faces a tough reelection campaign. This internal Republican conflict has opened a possible opportunity for Democrats to gain the Senate seat and majority.

The rally in Katy appeared as a premature celebration, with Vidaurre stating that supporting Cornyn equated to voting for a Democrat. Many Paxton supporters criticized Cornyn for collaborating with Democrats on gun legislation following the tragic 2022 Uvalde, Texas school shooting. They also reproached him for not removing the Senate filibuster to pass the Trump-endorsed SAVE Act for voting restrictions. This intense rivalry has cost Republicans a hefty $100 million as they vie for party leadership post-Trump.

Paxton and Cornyn each argued their merits. Cornyn emphasized his history of voting with Trump over 99% of the time. Paxton, on the other hand, cited his leadership in legal battles against Democrats as overshadowing Cornyn’s long political tenure. He criticized Cornyn’s career moves, stating his own actions surpassed Cornyn’s accomplishments in a short time.

Despite ongoing legal challenges and personal issues, Paxton, conversely, has been portrayed by his supporters as a resilient figure. The contentious political climate didn’t deter Paxton’s campaign, with loyal followers dismissing personal controversies as gossip.

The Republican Party is showing signs of internal division, remarked Brandon Rottinghaus, professor of political science at the University of Houston. He noted that the ideological struggle within the party has been a brewing issue for some time, with Trump’s MAGA movement gaining momentum. A Paxton win would mean greater influence of this populist faction, while a Cornyn victory would stabilize traditional conservative dominance.

Cornyn has cautioned that a Paxton nomination could lead to Democrats capturing a long-held Republican stronghold. He stressed the need for inclusivity and broad outreach to secure Republican interests.

Among Cornyn’s supporters, Vicki Fullerton felt betrayed by Trump’s backing of Paxton and worried about the financial strains on crucial races elsewhere. Cornyn himself voiced concerns over resource allocation impacting competitive contests in states like Michigan, Georgia, and North Carolina.

Amid these Republican challenges, strategist Chuck Rocha viewed the situation as potentially advantageous for Democrats in the midterms. Rocha highlighted voter frustration over economic issues as a commonality against Republican infighting. He pointed to the unity among Democrats with their candidate James Talarico and Latino voters returning due to economic and immigration policy concerns. A Democrat victory in Texas could shift the Senate balance in their favor.
