Republican primary Incumbent commissioner Sid Miller has frequently been the subject of critiques and scandal during his tenure. Miller faced vocal opposition from other statewide officials and members of the legislature who accused his office of corruption and ineptitude, including Governor Greg Abbott who endorsed his primary opponent, Nate Sheets. President Donald Trump, who had been a longtime supporter of Miller, renewed his endorsement the week before the election, but on election day Sheets won the primary with about 53% of the vote.

General election The construction boom of data centers caused by the development of A.I. systems has become a major issue in the campaign. There are hundreds of sites planned for construction in rural areas of the state which has led to Texas having one of the highest number of data centers in the country. Critics of these projects express concerns over the energy, water, and other resources that are consumed by the centers are placing a strain on local infrastructure. Incumbent Commissioner Sid Miller has been vocal about his concerns with the rapid expansion and has called for a moratorium on new construction. Miller has also requested that Governor Abbott call a special legislative session on the issue. Democratic nominee Clayton Tucker has made a moratorium on the construction of new data centers a main plank of his campaign. Tucker and Miller both attended a forum in Matagorda County against data centers with Miller saying of Tucker “I’d never endorse a Democrat, I’ve never campaigned for a Democrat, but this guy, he’s right on the issue."
