The March 2026 Texas Republican primary races in Texas were expensive and often contentious, with some party nominations left undecided. Without surpassing the 50% threshold needed to avoid a runoff, a number of statewide candidates are facing off in a May 26, 2026 primary runoff election.
At the top of the May ballot, will incumbent Sen. John Cornyn overcome the challenge from Texas Attorney General Ken Paxton? What issues are of most concern when making a decision of whom to support for the Republican U.S. Senate nomination? Who will win the Republican nomination for Texas Attorney General — state Rep. Mayes Middleton or Congressman Chip Roy? Will incumbent Commissioner Jim Wright be included on the Nov. General Election ballot for the opportunity to continue serving on the Railroad Commission of Texas? Or will his opponent Bo French get the chance to serve on the regulatory body over oil, natural gas, utilities and mining?
To answer these questions and more, the Hobby School of Public Affairs at the University of Houston conducted a representative survey of likely May 2026 Texas Republican primary runoff voters to assess their vote intention and opinions in the Republican Texas U.S. Senate, Texas Attorney General and Texas Railroad Commissioner primary runoff elections.
