Colin Allred (D) defeated incumbent Julie Johnson (D) in the Democratic primary runoff for Texas' 33rd Congressional District on May 26, 2026.
Allred and Johnson were the top two finishers in the March 3 primary, with 45.5% and 34.0% of the vote, respectively. They advanced to a runoff because neither received more than 50% of the vote.
Allred was first elected to represent an earlier version of the district in 2018. In 2024, Allred ran for U.S. Senate rather than seeking re-election and Johnson was elected to the U.S. House. Allred ran for U.S. Senate in 2026 before dropping out of that race and re-filing for the 33rd District.
