Christi Craddick and Warren Chisum have advanced to a runoff for the Republican nomination for a seat on the Texas Railroad Commission, which regulates oil and gas exploration statewide.
Craddick and Chisum finished ahead of four other Republicans on Tuesday for the Place 1 seat vacated by Elizabeth Ames Jones, who left to run for state Senate.
Born in Midland, Craddick is an oil and gas attorney whose father is former Texas House Speaker Tom Craddick.
Chisum is a state representative from Pampa, in the Texas Panhandle.
All candidates campaigned against overregulation by the Environmental Protection Agency.
The winner of the July 31 runoff will face Democratic opponent Dale Henry in November's general election.
