Mayes Middleton has put approximately $17 million of his own money into his campaign for Texas attorney general. The state senator and oil executive advanced to the May 26 Republican runoff against U.S. Rep. Chip Roy after receiving 39.2 percent in the March 3 primary. His personal spending has funded extensive advertising and ground operations that helped him finish first in a crowded field.
Self-Funding Creates Early Advantage
Middleton directed more than $10 million into the race before the primary and added millions more during the runoff period. This approach allowed his campaign to maintain a steady presence on television and digital platforms without relying on outside donors. In Texas Republican primaries, where turnout often stays low, such resources can determine which messages reach voters most effectively.
The scale of Middleton's investment stands out even among well-funded candidates. Official filings show the bulk came through personal contributions rather than loans or third-party support. Rival Chip Roy has drawn a late wave of outside contributions that could narrow the gap in the final days, according to recent reporting.
Endorsements Reinforce Conservative Credentials
Lt. Gov. Dan Patrick endorsed Middleton on May 5. The endorsement added institutional weight from the state's top Republican officeholder. Middleton also carries prior support from Donald Trump and several conservative organizations that have backed his legislative work.
These backers align with Middleton's emphasis on border security, election integrity measures, and opposition to progressive policies in state government. His record includes service in both the Texas House and Senate, where he represented districts focused on energy and rural issues.
