Christi Craddick

On March 16, 2018, Craddick with nearly 76 percent of the vote defeated her Republican primary opponent, Weston Martinez of San Antonio. She then defeated the Democrat Roman McAllen in the November 6 general election. Craddick polled 4,356,658 votes (53.2 percent) to McAllen's 3,588,625 ballots (43.9 percent). Another 236,720 votes (2.9 percent) went to the Libertarian Party nominee, Mike Wright.

In August 2014, she was elected chairman of the Texas Railroad Commission.

A native of Midland, Texas, Craddick won her seat in the general election held on November 6, 2012, in conjunction with the presidential contest.

Craddick's path to victory surged in the Republican runoff election held on July 31, 2012, when she easily defeated then State Representative Warren Chisum of Pampa in Gray County in the Texas Panhandle. Chisum is a former state legislative lieutenant of Tom Craddick. In that same election, most of the attention had focused not on the Craddick-Chisum race but on conservative Ted Cruz, who defeated Lieutenant Governor David Dewhurst for the Republican nomination to succeed U.S. Senator Kay Bailey Hutchison. Craddick raised triple the campaign contributions of Chisum, more than $1 million compared to $375,000, but Chisum had access to another $600,000 that he had accumulated earlier as a legislator. Craddick enjoyed the support of such wealthy donors as the entrepreneur James R. Leininger of San Antonio and the late homebuilder Bob J. Perry of Houston.

Craddick succeeded Elizabeth Ames Jones of San Antonio, who vacated the seat in February 2012. Jones ran for the District 25 seat in the Texas State Senate, which was ultimately won by the Republican physician Donna Campbell of New Braunfels, who unseated incumbent Senator Jeff Wentworth, a Moderate Republican from San Antonio, in the party runoff on July 31. Interim commissioner Buddy Garcia, an appointee of Governor Rick Perry, stepped down several weeks after the 2012 general election, and Perry named Craddick to complete the few days remaining in Jones' term.

Craddick's two Republican colleagues on the railroad commission were David J. Porter of Giddings in Lee County, formerly of Midland, and the former chairman, Barry Smitherman, formerly of Houston. Smitherman, elected to a two-year unexpired term in 2012, did not seek a full six-year term in 2014; he instead ran for Texas attorney general to succeed Greg Abbott, but came in third place in the Republican primary. Since 1995, when veteran Democratic member James E. Nugent was unseated by Charles R. Matthews, all railroad commissioners have been Republicans. Both Craddick and Porter have ties to the oil-rich Permian Basin of Midland/Odessa.

Craddick's father is State Representative Tom Craddick, a Midland businessman who was the Speaker of the Texas House from 2003 to 2009. Her mother is the former Nadine Nayfa, of Lebanese descent and originally from Sweetwater in Nolan County in West Texas. She has a brother, Thomas Russell Craddick, Jr. (born 1973). Craddick has a daughter, Catherine. The Craddicks are Roman Catholic.

Christi Leigh Craddick (born July 1, 1970) is one of three members of the Texas Railroad Commission, the elected regulatory body over oil, natural gas, utilities, and surface mining first established in 1891. She is a Republican. The commission ended all controls over railroads in 2005 but is still known as the "Railroad Commission" for historical reasons.

Mark Jones, a political scientist at Rice University, attributed Craddick's victory over Chisum to the "respect" within the GOP for her father. Tom Craddick is the longest-serving Republican legislator in Austin, having first been elected in 1968. He lost the Speakership in 2009 to Joe Straus, a moderate Republican from San Antonio, who initially prevailed through a coalition of mostly Democrats and sixteen maverick Republicans.

Craddick thereafter defeated the Democratic nominee, Dale P. Henry (born 1930), a retired petroleum engineer from Lampasas in Central Texas. Craddick polled 4,336,499 votes (56 percent); Henry, 3,057,733 (40 percent). The remaining 4 percent was cast for two minor-party candidates.
