The Democratic and Republican primary runoffs in Texas will be held on July 14.
Here's a look at who's on the ballots for the Republican and Democrat primaries in Dallas County:
Dallas County does not have any Republicans competing in July's runoff election.
Kim Olson and Candace Valenzuela will face off with each other to be the Democratic candidate for U.S. House District 24. Whoever wins will race against Republican Beth Van Duyne in November. The winner will replace incumbent Kenny Marchant.
Also on Dallas County's Democratic ballot will be the race for Texas House District 100. Incumbent Rep. Lorraine Birabil is facing a challenge from Jasmine Crockett for the party's nomination.
Audra Riley and Teresa Hawthorne are also running against each in the race for No. 3 Dallas County Criminal District Judge.
Who is Kim Olson?
Olson is a retired U.S. Air Force colonel who challenged Air Force policies preventing women from going to flight school and was among the first generation of female pilots, according to her website. She was one of the first women to command an operation flying squadron, commanded troops in Iraq after 9/11 and worked to modernize the Air Force's policy on sexual assault. She served in the Air Force for 25 years. She was inducted into the Texas Women's Hall of Fame in 2014.
Olson wants to expand the Affordable Care Act and make sure affordable, quality health insurance is available to everyone in the country. She believes climate change is "the most immediate threat facing our nation" and that urgent action is needed. She would end "corporate welfare" for polluters while promoting renewable energy.
She has pledged to co-sponsor and vote in favor of federally banning police chokeholds, end for-profit policing and prisons and require police departments that receive federal funds to publish misconduct records.

Who is Candace Valenzuela?
Valenzuela is the first Latina and African-American woman to have served on on the Carrollton-Farmers Branch school board. During her childhood, her family was homeless at one point after her parents' finished serving in the U.S. military, her website said. The experience led her to become deeply involved in education after she was the first person in her family to graduate from college. When she became a mother, Valenzuela said she was inspired to enter public service and expand educational opportunities.
Valenzuela believes health care is a human right. After experiencing medical debt herself, Valenzuela would expand the Affordable Car Act, implement a public health care option and lower the cost of prescription drugs. She would work to offer "strong incentives" to businesses to help combat climate change by providing "massive investment from the federal government."
If elected, she would also fight for universal pre-K, investment in community colleges and vocational programs, and higher teacher salaries. She also supports creating a pathway to citizenship and codifying the DREAM Act.
