On Tuesday, Railroad Commission Chairman Wayne Christian secured the Republican Party nomination to seek another term as one of Texas’s top oil and gas regulators. In winning the GOP primary runoff election, Christian fended off a surprise challenge from West Texas-based attorney Sarah Stogner. Stogner had run as a reformer, accusing Christian of being in the pocket of the industry, and highlighting a $100,000 campaign contribution he accepted from a company that he oversaw as a regulator.
