On August 4, a 3-judge U.S. District Court redrew 5 Texas congressional districts (15, 21, 23, 25 and 28). The March primary results for those 5 districts are now of no significance. Candidate filing for those 5 districts is re-opened. All candidates will run as though the election were non-partisan in November. If no one gets 50%, a run-off will be held in December.

The 5 incumbants in those 5 districts are Ruben Hinojosa (D), Lamar Smith (R), Henry Bonilla (R), Lloyd Doggett (D), and Henry Cuellar (D).
