Mark Teixeira, a former Major League Baseball first baseman, is currently leading a crowded GOP primary to succeed Rep. Chip Roy in Texas’ 21st Congressional District. In his initial political campaign, Teixeira has injected millions of his own money and secured high-profile endorsements, including backing from former President Donald Trump, positioning himself strongly ahead of the March 3 primary.
The 21st District, covering parts of San Antonio and Republican-leaning Hill Countrycounties, is considered safely red, having favored Trump by nearly 22 points under the new boundaries. Since Roy is vacating the seat to run for Texas attorney general, the Republican primary is expected to effectively determine the next congressman.
Campaign Funding and Prominent Endorsements Boost Teixeira’s Advantage
Teixeira, once a standout first baseman with the Texas Rangers and New York Yankees, has outpaced rivals financially, loaning $2.5 million to his campaign and raising an additional $545,000 from contributors. Notable endorsements include Texas Governor Greg Abbott—who Teixeira has publicly supported in pushing private school vouchers—and nine other members of Texas’ Republican congressional delegation.
Jon Taylor, chair of political science and geography at the University of Texas at San Antonio, emphasized Teixeira’s widespread backing and campaign resources as crucial factors.
“It seems like it’s a slam dunk that he’ll end up winning the Republican nomination,”
Taylor said, adding that with a dozen candidates splitting the vote, a runoff remains a possibility.

“But with [11 other] primary candidates, getting 1 or 2% of the vote here, or 4 or 5% of the vote here, it’s possible that … there’s just enough people in the primary with enough votes to force a primary runoff.”
Contenders: Diverse Pool of Candidates Challenges Teixeira’s Lead
Among Teixeira’s competitors are Daniel Betts, an Austin-based defense attorney endorsed by the San Antonio Express-News; Kyle Sinclair, former vice chair of the Bexar County Republican Party; Trey Trainor, who headed the Federal Election Commission; and Mike Wheeler, ex-chair of the Kendall County GOP. Betts, Wheeler, Navy veteran Jason Cahill, and engineer Paul Rojas have each raised at least $100,000, sharing the highest fundraising tiers alongside Teixeira.
Teixeira’s opponents have criticized him as an opportunistic newcomer to the district and questioned his conservative credentials despite his campaign claims to uphold
“the conservative principles that make Texas and America great,”
as stated by Teixeira in a recent local TV advertisement.
Background: Teixeira’s Athletic Career and Residency Shifts
Drafted by the Texas Rangers in 2001, Teixeira played five seasons in Arlington before retiring in 2016 after eight years with the New York Yankees. He returned to Texas in 2021 and now resides in Bee Cave, a small town near Austin. His ties to the community have come under scrutiny amidst the political scrutiny.
During a January debate in San Antonio, volunteers opposing Teixeira distributed flyers highlighting comments he made roughly ten years ago encouraging athletes to speak out on climate change. At the time, Teixeira served on the board of the Emerald Corridor Foundation, a conservation group focused on restoring natural spaces in Atlanta.
Conservative Messaging Aligns with Trump Administration’s Policies
Despite past remarks about climate activism, Teixeira has campaigned firmly as a conservative aligned with Trump-era policies, focusing on border security, government spending cuts, and gun rights. His strong stance was evident after the fatal shooting of Renee Good by an Immigration and Customs Enforcement agent in Minneapolis, when Teixeira publicly declared on X, “I stand with ICE.”
Political analyst Mark Jones of Rice University noted Teixeira’s dominant position but acknowledged potential challenges ahead.
“It’s going to be a race where we’re going to see Teixeira finish well ahead of the pack, and then it’ll be whichever of those other candidates is able to do well in the home stretch,”
Jones explained.
Profile of Notable Challengers and Their Political Experience
Trey Trainor announced his campaign about a month after Teixeira’s launch. Trainor served as general counsel for the Texas Secretary of State, the Republican Party of Texas, and Gov. Rick Perry’s 2012 presidential bid. He also played a role in Texas’ 2003 congressional redistricting, which favored Republicans. Although Trump’s endorsement of Teixeira was a setback to Trainor, he has vowed to “stand shoulder-to-shoulder with Trump” if elected.
Mike Wheeler, an experienced political figure, currently sits on the Texas GOP’s State Republican Executive Committee. His background in global finance earned him a 2024 appointment from Trump as a senior advisor to the Small Business Administration. Kyle Sinclair, who previously sought Congress in the neighboring 20th District and lost to Democratic Rep. Joaquin Castro, is another contender with political credentials.
Daniel Betts is running on an evidence-driven conservative platform, emphasizing combating fentanyl by labeling Mexican drug cartels as terrorist entities and expanding addiction treatment access. Betts, a former chemist, previously ran for Travis County district attorney, losing in a Democratic stronghold.
Jason Cahill, a Navy veteran and oil and gas businessman, has invested $250,000 in his campaign but lacks prior elected office experience. He presents himself as a political outsider similar to Trump, competing with Teixeira on comparable policy themes.
Other Candidates Contributing to the Competitive Race
Additional participants include Jacques Dubose, a Navy veteran and former Boerne Chamber of Commerce chair; Marine Corps veteran Zeke Enriquez; attorney Heather Tessmer; arbitrator Weston Martinez, known for representing January 6 clients; and Peggy Wardlaw, a petroleum engineer.
Implications and What to Watch for Moving Forward
With multiple qualified candidates and significant personal spending by Teixeira, the Texas 21st District GOP primary is poised to be a closely watched contest. The possibility of a runoff remains high due to the crowded field, and the outcome will signal the direction of conservative representation in this strategically important district. Observers will be attentive to late-stage campaign efforts and the potential impact of endorsements and grassroots mobilization as voters weigh in on March 3.
