Live updates: Texans head to the polls for key primary runoff races this Election Day

As Texans were heading to the polls to cast their ballots in this year's primary runoff elections, ABC13 has received several calls about issues with Fort Bend County polling locations.

On Tuesday afternoon, Congressman Christian Menefee shared the following statement regarding the issues at the Fort Bend County polls.

"To every voter in Fort Bend County: please still go vote. Officials are working to fix this as quickly as possible. In the meantime, eligible voters may cast a provisional ballot. Your vote matters, and we want you to cast it," Congressman Christian Menefee said. "Fort Bend County officials must do what is necessary to extend poll hours tonight. Voters should not lose a single minute of their right to vote because of a technical failure outside of their control. The right to vote is too important to shortchange anyone."

Eyewitness News has reached out to Fort Bend County officials about problems with voting locating, but has not received comment.

Voters in Texas go to the polls on Tuesday to decide the Republican nominee in a pivotal Senate race that could decide control of the Senate -- and serves as a test of President Donald Trump's influence.

Trump's last-minute endorsement in the Texas Senate primary runoff race of Attorney General Ken Paxton over incumbent Republican Sen. John Cornyn has shaken up a race that could become critical for the fight to control the Senate next year.

Cornyn narrowly led the field in March's primary with 42% of the vote, followed by Paxton's 40%, to make the runoff over GOP Rep. Wesley Hunt.

Eyewitness News caught up with all of the candidates for Harris County Judge during the early voting period when they went to vote.

All had very positive outlooks going into today.

On the Republican ballot, we have former city council member and former county treasurer Orlando Sanchez. He's taking on Warren Howell, who is the president of an insurance company.

"We haven't had effective or efficient government for eight years. And I think everybody's hungry for that," Sanchez said.

"I want you to know we have a plan. We have a plan to fix everything. I mean everything. And so that's why I think we have a great chance," Howell said.

The Democratic candidates are familiar names to voters, including Dr. Letitia Plummer, who served as a city council member for five years. She's up against Annise Parker, the former mayor of Houston.

While the candidates have differences in priorities and leadership styles, one thing they largely agreed on was that change is needed for Harris County residents.

"I'm feeling great about Tuesday. The stars have aligned. Every single thing that we've predicted to give us the best opportunity of winning this race is in place now," Plummer said.

"The county judge's role is not just to be standing in front of cameras. It's to be hands-on in the community, understanding what's going on," Parker said

Runoff elections typically see lower voter turnout, so it's all about who shows up to the polls.

You can vote tonight as long as you're in line by 7 p.m.
