Breaking Down the 2026 Texas Republican
Senate Primary: Cornyn, Paxton & Hunt
Republican Primary Overview — Texas U.S. Senate (2026)
The Republican primary for Texas’ U.S. Senate seat is one of the most watched contests in the 2026 midterms, partly because the outcome could shape the general election matchup in a state that remains crucial for control of the Senate.
At the center of the GOP contest is incumbent Senator John Cornyn, who’s facing a serious challenge from Texas Attorney General Ken Paxton — and possibly other contenders like U.S. Rep. Wesley Hunt.
Who Are the Candidates?
John Cornyn (Incumbent U.S. Senator)
- Cornyn is a long-serving Republican senator who has represented Texas in Washington since 2002.
- Traditionally part of the GOP establishment, he’s seen as more of a traditional Republican voice within the Texas GOP.
- Has backing from party leadership and national GOP infrastructure — including Senate GOP committees looking to hold the seat in November.
Ken Paxton (Texas Attorney General)
- Paxton has cultivated strong support among more conservative and MAGA-aligned Republican voters.
- Despite legal controversies and prior impeachment in the state legislature, he maintains a base of die-hard support in Republican primaries.
- Long seen as the frontrunner in many early GOP primary surveys.
Wesley Hunt (U.S. Rep. — potential spoiler)
- Talk of a Hunt entry has circulated, and several polls include him as a third option.
- His candidacy could complicate the dynamics by siphoning votes from both Paxton and Cornyn, potentially forcing a runoff if no candidate breaks 50 %.
What the Polls Show
The GOP primary remains very close and fluid, with no clear dominant candidate — even as March 3, 2026 draws near:
Recent statewide Republican primary polling averages show:
- Ken Paxton: ~34–36 %
- John Cornyn: ~30–33 %
- Wesley Hunt: ~20–22 % (when included)
- Undecided: 10 – 15 %+ in some surveys
In many polls, Paxton narrowly leads Cornyn, but the margin is within the poll’s margin of error — meaning the race is effectively tied. Some surveys even show Cornyn slightly ahead or both men neck-and-neck.
Notable Trends
- Cornyn tends to do better with female voters, while Paxton has stronger support among male primary voters.
- Undecided voters remain high, giving both campaigns room to shift the narrative before March.
Dynamics & What’s at Stake
For Cornyn
- His strategy is often rooted in establishment experience and electability, arguing he can better hold the seat for Republicans in November.
- Cornyn has sometimes trailed in early polls, but advertising and party support have buoyed his numbers into a statistical tie.
For Paxton
- Paxton’s appeal is strongest among the GOP base’s most conservative voters, especially those loyal to former President Trump and more hardline positions.
- A potential Paxton nomination is attractive to some GOP voters but has raised concerns among establishment Republicans about general election viability, given his controversies and vulnerability among broader electorates.
Potential Runoff
Because Texas requires a majority to win the primary outright, and no candidate is likely to hit 50 %, a
runoff election in May 2026 is a strong possibility — especially if Hunt remains in the field.
Why This Matters for November
Who wins the GOP primary isn’t just an intra-party fight — it’s likely to influence the general election contest for the Senate:
- A Paxton nomination could provide Democrats with unusual opportunities in November, especially if Republican voters are split in the primary and if Paxton remains a polarizing figure.
- Cornyn, though more establishment, faces challenges in energizing all wings of the GOP base, especially compared to hardline challengers.
National Republicans have signaled they’re willing to
invest heavily in helping Cornyn hold off Paxton to prevent what they see as a more vulnerable nominee.
