State Sen. Mayes Middleton holds a commanding position in the May 26 Republican primary runoff for Texas attorney general, reflecting trader consensus on his advantages over U.S. Rep. Chip Roy. Middleton topped the March primary with 39 percent of the vote after self-funding nearly $14 million, while Roy placed second at 32 percent. Lt. Gov. Dan Patrick's May endorsement and a University of Houston poll showing Middleton ahead 48-39 percent among likely voters have reinforced this edge. Roy's congressional record and occasional independence from party leadership have limited his momentum in the final weeks, leaving Middleton well positioned to secure the nomination against the Democratic opponent in November.
