In the lead-up to the 2024 Texas House Republican primaries, a fierce and highly competitive atmosphere emerged, marked by unprecedented campaign spending. This cycle saw substantial financial backing from West Texas oil magnates Tim Dunn and Farris Wilks, who supported far-right challengers. Governor Greg Abbott also invested millions to unseat GOP incumbents who opposed private school vouchers, a key initiative for his administration. Meanwhile, Attorney General Ken Paxton targeted legislators who participated in his impeachment proceedings in 2023.
Fast forward to 2026, and the political landscape has significantly shifted following a legislative session in which Republicans advanced major GOP priorities such as vouchers, congressional redistricting, and various socially conservative measures. This time around, Dunn and Wilks’ political influence seems to be less pronounced. In the latter half of 2025, their affiliated groups contributed funds primarily to a select few Republican incumbents and candidates vying for open seats, a stark contrast to previous cycles where they heavily financed aggressive challengers.
The current divide among Republicans centers around tort reform, with Texans for Lawsuit Reform (TLR) focusing its efforts on three Republican incumbents who resisted its agenda during the last legislative session. In response, trial lawyer organizations are investing heavily to defend those lawmakers.
One of the most contentious races is occurring in San Antonio’s House District 121, where TLR has allocated nearly $900,000 in support of David McArthur, the Republican challenger to incumbent Marc LaHood. LaHood, backed by significant contributions from personal injury law firms and related groups, including the Texas Trial Lawyers Association and Texans for Truth and Liberty, has amassed over $1 million from various medical and legal sources.
LaHood played a crucial role in defeating Senate Bill 30, which aimed to limit compensation for personal injury claims, a key priority for TLR. As a personal injury and criminal defense attorney, LaHood advocated for amendments to SB 30 and was instrumental in halting two other bills that TLR sought to advance.
Following the legislative session, LaHood found himself in a public dispute with TLR’s president, accusing the organization of negotiating in bad faith and criticizing SB 30 as a flawed measure that would unjustly deny assistance to victims of serious harm.
These legislative setbacks have highlighted a declining influence for TLR in Austin, an organization that once played a pivotal role in the Republican transformation of the state. The proposed SB 30 initially sought to impose strict limits on the damages that accident victims could receive but was considerably diluted in the House before ultimately failing to meet critical deadlines.
Furthermore, TLR’s other two legislative priorities—bills aimed at restricting payouts against commercial vehicle owners and limiting public nuisance claims—also stalled in committee.
The organization’s diminishing clout comes amid increasing tensions with the far-right faction of the GOP. TLR has previously endorsed a Republican candidate who opposed Paxton in 2022, leading to accusations from Paxton’s supporters that TLR had a hand in orchestrating his impeachment, a claim TLR’s leadership has categorically denied.
Among TLR’s targets are a growing number of right-wing trial lawyers, including LaHood and Rep. Mitch Little of Lewisville, who have gained prominence within the Texas Republican Party. Historically, trial lawyers were closely associated with the Democratic Party, but their increasing visibility in Republican primaries has prompted TLR’s chairman Dick Weekley to express concern over “Democratic trial lawyers” masquerading as conservative allies.
The battle for influence extends to the race to fill the seat of outgoing Rep. Giovanni Capriglione in North Texas’ House District 98, where significant campaign contributions have been made by both TLR and trial lawyer groups. In the latter half of last year, the Texas Trial Lawyers Association and Texans for Truth and Liberty provided $127,500 to Armin Mizani, the Republican mayor of Keller. In contrast, TLR invested six figures in his opponent, Fred Tate, who champions lawsuit reform as a means to reduce costs driven up by “frivolous lawsuits” from personal injury lawyers.
As the primary season unfolds, TLR’s apparent shift away from aggressive spending raises questions about its future strategy. While Dunn and Wilks may be taking a backseat this cycle, the Texas House has undergone a significant transformation, resulting in fewer establishment Republicans left to challenge. This shift has propelled the chamber further right and introduced new leadership aligned with conservative goals.
Abbott’s success in pushing through the school voucher initiative has also altered the dynamics of the primary battles. With every House Republican seeking re-election having voted in favor of the program, they received a blanket endorsement from former President Donald Trump, complicating efforts by tort reform groups to target incumbents.
Despite TLR’s active spending in late 2025, recent indications suggest that the organization may not continue its financial support for endorsed challengers in competitive primaries. Nevertheless, other entities within the TLR network continue to contribute to those candidates, potentially mitigating the impact of TLR’s funding withdrawal.
In response to TLR’s funding decisions, McArthur has initiated a significant advertising campaign, while LaHood has countered with his own messaging. The evolving landscape of the Texas Republican primaries reflects a complex interplay of interests as various factions vie for control and influence within the party.
As the primaries approach, the outcomes will undoubtedly shape the future direction of Texas politics, revealing the ongoing tensions between traditional Republican values and the emerging influence of trial lawyers within the party.
