Democrat Jon Rosenthal held a commanding lead over Bo French Tuesday night, inching toward a dramatic upset that would break decades of complete Republican control over Texas' oil and gas commission, which oversees the state's colossal fossil fuel industry.

Rosenthal declared victory at about 10:20 p.m. after other statewide Democratic candidates, including James Talarico and Gina Hinojosa won their elections for U.S. Senate and the governor's mansion, respectivley.

The Associated Press has not yet called the race.
