State Sen. Mayes Middleton holds a clear polling advantage over U.S. Rep. Chip Roy heading into the May 26 Republican primary runoff for Texas attorney general, driven by Middleton’s stronger March primary finish and substantial self-funding that enabled aggressive advertising. A University of Houston poll conducted in early May showed Middleton ahead 48 percent to 39 percent, consistent with his 39 percent primary share compared to Roy’s 32 percent. Both candidates position themselves as strong conservatives focused on election integrity measures, lawsuits targeting federal policies, and potential challenges to long-standing Supreme Court rulings. No major endorsements or events have altered the race in recent days, leaving trader consensus to reflect Middleton’s resource and momentum edge in this low-turnout contest.
