Live updates: Multiple key races called for primary election runoffs, AP projects

The race to be the next Harris County judge is down to two candidates.

Unofficial results show November's general election will come down to Republican Orlando Sanchez and Democrat Letitia Plummer, both former Houston City Councilors.

Sanchez won his runoff single-handedly. But on the Democratic side, between former Council Member Dr. Letitia Plummer and former Houston Mayor Annise Parker, the race came down to just over 2,500 votes.

On the Republican side, Sanchez beat Warren Howell, the president of an insurance company, by nearly 36,000 votes.

Sanchez has said county government hasn't been working for the community in recent years, pointing to issues like the backlog in the criminal justice system and stalled flood projects.

So, it'll be Sanchez versus Plummer in November's general election for county judge, replacing incumbent Lina Hidalgo, who chose not to seek reelection.

The race to be the next Harris County judge is down to two candidates, with Republican Orlando Sanchez and Democrat Letitia Plummer winning their respective primaries.

The Associated Press projected that Christian Menefee has won the District 18 Congressional seat, defeating longtime Congressman Al Green in a race shaped by redistricting and defined by age and experience.

Those who live in District 18 have cast votes for their representative four times in less than a year, with previous representatives including Sheila Jackson Lee and former Houston mayor Sylvester Turner.

The new congressional lines drastically changed Green's longtime 9th Congressional District, drawing his home into a brand new 18th district.

The Associated Press has projected that Mayes Middleton will win the Republican nomination for Texas Attorney General, defeating his opponent, Chip Roy.

For the Democrats, the Associated Press has projected that Nathan Johnson will be the party's nominee for Texas Attorney General, defeating Joe Jaworski.

After the Associated Press projected that Texas Attorney General Ken Paxton would win the Republican nomination for U.S. Senate, the GOP candidate spoke to supporters in Plano.

"We went up against $150 million and all the attacks in the world, and we proved that Texas is not for sale," Paxton said. "Change was on the ballot, and change won."

Incumbent Sen. John Cornyn also spoke to his supporters in Austin following his projected defeat.

We've come up short in this primary runoff," Cornyn said. "Over the next 7 months, I intend to continue my work to make this nation a better place for all Texans and all Americans."
