David Henry Dewhurst (born August 18, 1945) is an American politician, businessman, and attorney who served as the 41st Lieutenant Governor of Texas, serving from 2003 to 2015. A member of the Republican Party, he was the Texas Land Commissioner from 1999 to 2003. Dewhurst was a candidate in 2012 for the U.S. Senate seat vacated by the retiring Republican Kay Bailey Hutchison, but he lost his party's runoff election to former Solicitor General Ted Cruz, who went on to win the general election. Dewhurst was a candidate for a fourth four-year term in the Republican runoff election held on May 27, 2014. He was handily unseated by his intraparty rival and fellow Houstonian State Senator Dan Patrick who also led the primary balloting with 550,769 votes (41.5 percent). Dewhurst trailed with 376,196 votes (28.3 percent). Eliminated in the primary were Texas Commissioner of Agriculture Todd Staples with 235,981 votes (17.8 percent) and Texas Land Commissioner Jerry E. Patterson with 165,787 (12.5 percent). Patterson had succeeded Dewhurst as land commissioner in 2002 when Dewhurst was first elected as lieutenant governor. On a night of "embarrassingly low" voter turnout (approximately 4% of registered voters), the incumbent finished with only 262,086 votes (34.9 percent), compared to Patrick's 487,829 (65.1 percent). Dewhurst's third term as lieutenant governor ended on January 20, 2015. He currently serves as an advisory board member at the United States Secretary of Energy led by former Governor Rick Perry who was appointed by President Donald Trump in 2017.
