Candace Valenzuela defeated Kim Olson in the Democratic primary runoff for Texas’ 24th Congressional District. Valenzuela received 60% of the vote to Olson’s 40%.
Former U.S. Secretary of Housing and Urban Development Julián Castro (D), U.S. Sens. Elizabeth Warren (D-Mass.) and Kamala Harris (D-Calif.), several members of the U.S. House, and multiple congressional caucus PACs endorsed Valenzuela, who served on the Carrollton-Farmers Branch school board. The Dallas Morning News, the Fort Worth Star-Telegram, and multiple organizations supporting military veterans in politics endorsed Olson, a retired Air Force colonel.
In 2018, retiring incumbent Kenny Marchant (R) won re-election by three percentage points. Major independent observers rated the general election as a toss-up or tilt Republican.
