Gov. Greg Abbott officially has a challenger for the midterm elections. Former Dallas County Sheriff Lupe Valdez has won the Democratic gubernatorial runoff against Houston businessman Andrew White. She is the first openly gay and Latina nominee for Texas governor.

Colin Allred has won the Democratic nomination for U.S. House District 32 — a Dallas-area seat — over Lillian Salerno. Both Democrats worked in the Obama administration, and the race garnered national attention. Allred will go on to challenge Republican incumbent Rep. Pete Sessions in the fall.

In Collin County, Democrat Lorie Burch has won the U.S. House District 3 runoff. That means her competitor Sam Johnson will not have a chance to replace the retiring Republican Rep. Sam Johnson. She will go on to challenge Plano Republican Van Taylor in November. He stepped down from his state Senate seat to run for Congress.

Elsewhere in North Texas, a congressional race that started with 16 candidates has been narrowed to two. Democrat Jana Lynne Sanchez and Republican Ron Wright will face off in the fall for retiring Rep. Joe Barton's District 6 seat.
