Central Texas congressional races start taking shape,

21st Congressional District

In a district that includes swaths of Central and South Austin, as well as the north side of San Antonio and six Hill Country counties, Chip Roy, the former chief of staff to U.S. Sen. Ted Cruz, R-Texas, and former first assistant attorney general under Attorney General Ken Paxton, defeated Matt McCall, who lives in Boerne and owns a business that provides human tissue for American military hospitals. Cruz had endorsed and campaigned with Roy.

Roy, who received 52.7 percent of the vote, will be the favorite to replace U.S. Rep. Lamar Smith, R-San Antonio, who is retiring after holding the seat in the conservative district for more than three decades.

In the district’s Democratic primary runoff, Joseph Kopser, an Austin tech entrepreneur who served 20 years in the Army, bested Mary Wilson, a minister who lives in Austin, with 58 percent of the vote. Wilson had received the most votes in the March primary, but Kopser had raised much more money — a little more than $1 million, more than any other candidate from either party running in the district.

27th Congressional District

Michael Cloud, owner of a Victoria communications firm and former chairman of the Victoria County GOP, easily won the Republican nomination over Bech Bruun, a former chairman of the Texas Water Development Board, in a district that covers areas of the Gulf Coast battered by Hurricane Harvey and includes parts of Bastrop and Caldwell counties. Cloud won 61 percent of the vote.

Bruun, who served in the administrations of Govs. Rick Perry and Greg Abbott, had raised more money and was the establishment favorite. But Cloud had won the endorsement of the Club for Growth, the limited government advocacy group.

On the Democratic side, Eric Holguin, a former employee at the New York City comptroller’s office, defeated Raul “Roy” Barrera, a security officer at the federal court in Corpus Christi, with 62 percent of the vote.

U.S. Rep. Blake Farenthold, R-Corpus Christi, announced his retirement from the seat in December following news reports that he had used a congressional Office of Compliance account to settle a sexual harassment lawsuit brought by his former communications director.

All four runoff candidates — and five others — are slated to square off in a June 30 special election to finish out Farenthold’s current term.

10th Congressional District

Mike Siegel defeated Tawana Walter-Cadien with 69.9 percent of the vote for the Democratic nomination in a district that stretches from Lake Travis to near Houston and includes the Austin neighborhoods of Rosedale, Allandale, Crestview, Brentwood and North Loop.

Siegel, an Austin assistant city attorney, will face Republican U.S. Rep. Michael McCaul, R-Austin, in November.

25th Congressional District

Democrat Julie Oliver defeated Chris Perri with 52.2 percent of the vote in a district that runs from Wimberley to near Fort Worth and includes Lakeway, West Lake Hills, Rollingwood and areas of West Austin, Central Austin and East Austin.

Oliver, 45, an attorney and controller for St. David’s HealthCare, will face U.S. Rep. Roger Williams, R-Austin, in the general election.

31st Congressional District

Democrat Mary Jennings “MJ” Hegar defeated Christine Eady Mann with 62.2 percent of the vote in a district that encompasses all of Williamson County and most of Bell County. Hegar will face U.S. Rep. John Carter, R-Round Rock, in November.

Hegar, 42, of Round Rock is an author and public speaker. She also is a former Air Force pilot who was awarded a Purple Heart after being injured in an ambush in Afghanistan.
