Updated at 10:56 a.m. March 7

Editor’s note: This post has been updated March 8 to include a comment from Democratic candidate Tawana Walter-Cadien.

With 100 percent of precincts reporting, incumbent Michael McCaul has won the Republican primary race for U.S. District 10 Representative with 41,881 votes or 80.08 percent of all votes. Challenger John W. Cook received 19.91 percent of all votes, totaling 10,413 votes.

“Thank you for your faith in me to represent you in the nation’s capital,” McCaul said in a statement. “There is still more work to be done, and I am committed to continuing my efforts to keep Texas families safe and grow our local economy. It remains an honor to go to work every day to fight for your values in Washington. May God bless Texas and the United States of America.”

Democratic candidate Mike Siegel led the Democratic primary race for U.S. District 10 Representative with 39.96 percent of votes—15,434 votes—with all precincts reporting. However, Siegel is headed toward a runoff election as he received less than 50 percent of the vote.


“We feel very good, very thankful to the voters of the Texas 10th [congressional district],” Siegel said. “We’re going to keep working hard, knocking on doors across the nine counties of the Texas 10th [district], [and]reaching out to voters to figure out what people care most about and to share the message and priorities of our campaign.”

He will be joined by Tawana Walter-Cadien who received 17.96 percent of the vote—6,938 votes.

“I am grateful for the opportunity to have another chance to speak with the voters about what my vision is for Congressional District 10,” Walter-Cadien said. “I have a history of doing just what I have been doing along, which is being the voice for those who feel voiceless. It is important to me that across the board citizens understand that they deserve to have true representation. It’s not about a partisan opportunity; to me it’s about people.”

The two Democratic candidates shared the election results on their social media pages.

The primary election runoff date will be May 22.

All results are unofficial until canvassed.

Published 11:07 p.m.

With more than half of all precincts reporting in U.S. District 10, incumbent Michael McCaul and candidate Mike Siegel lead the races for the Republican and Democratic primaries, respectively.

With 53.27 percent of Republican precincts reporting in District 10 on Tuesday night, McCaul has received more than 80 percent of votes in the Republican primary race, according to unofficial election results. Democratic candidate Siegel leads the primary election with 41.63 percent of votes with 51 percent of Democratic precincts reporting, according to unofficial election results from the Texas Secretary of State office’s website. All results are unofficial until canvassed.


Texas’ 10th congressional district spans multiple counties from the Greater Houston area to the Austin metro area.

Democratic candidates for the March 6 primary election include Siegel, Madeline K. Eden, Tawana Walter-Cadien, Matt Harris, Kevin Nelson and Tami Walker. Republican candidates include John W. Cook and McCaul.

McCaul did not respond to a request for comment Tuesday night.

Siegel could be headed toward a runoff election, as he likely received less than 50 percent of the vote. He could be joined by Walter-Cadien, who has received 16 percent of the vote; Walker, who has received 15 percent of the vote; or Eden, who has received nearly 14 percent of the vote.

With more than half of all precincts are reporting as of 11:15 p.m. Tuesday, candidates received the following percentages:


  • Cook: 19.26 percent
  • McCaul: 80.73 percent


  • Siegel: 41.63 percent
  • Walter-Cadien: 16.87 percent
  • Walker: 15.33 percent
  • Eden: 13.85 percent

  1. I hope Siegel or Cadien (whoever wins the run-off) can beat No Town Hall McCaul, but District 10 is horribly gerrymandered and stretches from Volente all the way to western ‘burbs of Houston. So it’s not likely. Meanwhile, McCaul will continue never meeting constituents face to face in Travis County.
