In preliminary voting results, U.S. House of Representatives incumbent Lamar Smith, who has served in Congress since 1987, clinched the Republican nomination for the District 21 race with 76.5 percent of the vote.
"I am very happy with the results and very appreciative of the support I received from voters of the 21st district," Smith said. "It is very reassuring to have voters' approval."
"What worries me the most is that Mr. Smith will take this as an endorsement of what he’s doing, [which is] clearly supporting laws that are against the Bill of Rights and are unconstitutional," Mack said. "My hope is that he will reassess [the Stop Online Piracy Act] and some of these other horrible laws and start conducting himself as a true Texan."
SOPA, introduced earlier this year, has been criticized for potentially infringing on freedom of speech and innovation. Proponents said the act would help combat the illegal download, streaming and trafficking of intellectual property on foreign websites, such as Pirate Bay.
