A pair of San Antonians running for U.S. Congress claimed victory early Tuesday night.
In District 20, Joaquin Castro captured 64 percent of the vote compared to 33 percent for Republican David Rosa.
Castro (pictured) replaced retiring Rep. Charlie Gonzalez in a safely Democratic district. Joaquin is the twin brother of San Antonio Mayor Julian Castro, who gained national fame as keynote speaker of the Democratic National Convention.
In District 21, Republican incumbent Lamar Smith cruised to victory, besting Democratic opponent Candace Duval by a 63 percent to 33 percent of the vote. Smith has held that seat since 1987.
Earlier this year, Smith spoke out against President Obama's healthcare reform bill, saying, "This is the first time ever that the federal government has involved themselves in the personal lives of Americans, to the extent that they are telling them they have to buy something."
Other Texas races
Elsewhere in Texas, Democratic U.S. Rep. Lloyd Doggett has won re-election and will represent a new congressional district in Central Texas. Doggett defeated former San Marcos Mayor Susan Narvaiz on Tuesday.
Doggett switched to the new 35th Congressional District after the lines of his old district were redrawn to include more Republicans. The 35th is a solidly Hispanic district that stretches from Austin to San Antonio.
Nearly half of the district was represented by Doggett under the old voting map. Doggett is a former justice on the Texas Supreme Court who was first elected to Congress in 1994.
Democrat Filemon Vela has been elected to Congress out of a new U.S. House district in South Texas. Vela defeated Republican Jessica Puente Bradshaw Tuesday in the race for the 34th Congressional District.
Vela was considered a favorite in the race to win the heavily Latino district, which runs down the Texas coast into the Rio Grande Valley. Vela, a Brownsville attorney, is the son of a longtime former federal judge in the city.
His wife is a state appeals court judge who decided to drop her bid this year to become the court's chief justice due to her husband's run.
Democrat incumbent Henry Cuellar held off Republican William R. Hayward to retain the US Representative District 28 seat.
