Mayes Middleton holds a commanding lead in the May 26 Republican primary runoff for Texas attorney general, driven by his substantial self-funding of nearly $14 million that propelled him to first place in the March primary and sustained heavy advertising. A University of Houston poll from early May showed Middleton ahead of U.S. Rep. Chip Roy by nine points among likely voters, a margin reinforced by Lt. Gov. Dan Patrick’s endorsement days later. Both candidates emphasize using the office to pursue conservative litigation on election integrity and challenges to longstanding Supreme Court precedents, yet traders view Middleton’s financial resources and alignment with state party leadership as decisive advantages in the low-turnout runoff. Roy’s congressional record and early frontrunner status have not offset these structural edges.
