Incumbent U.S. Rep. Michael McCaul, R-District 10, easily won the Republican primary May 29 with 84 percent of the vote and will face Democratic winner Tawana W. Cadien in November.

McCaul said he was not surprised at the results and is not anticipating Cadien to be much of a threat in the November general election. He also plans to help Republican presidential candidate Mitt Romney with his campaign.

"The people in the district know me," he said on the morning of May 30. "There's trust there, and we're pretty well-known."

McCaul's oppononent, Eddie Traylor, an Air Force veteran and retired pilot, said he will not seek to run in another election and plans to support McCaul in November.

"I simply did not get out the message. People are not concerned enough," he said.

McCaul is seeking his fifth term in office and received 39,502 votes to Traylor's 7,657 votes. He said his district map changed only a little with the addition of more parts of western Travis County and losing part of Harris County outside of Houston.

District 10 covers part of the Austin area, namely the northwest part and Pflugerville, and spans eight counties to the Houston suburbs.

During his time in Congress, McCaul spent six years as a member of the House Committee on Homeland Security. He now serves as chairman of the oversight subcommittee that oversees all Department of Homeland Security operations.

Before being elected to Congress, McCaul served as chief of Counter Terrorism and National Security in the U.S. Attorney's Office in Texas and led the Joint Terrorism Task Force charged with detecting, deterring and preventing terrorist activity. He served as Texas deputy attorney general under U.S. Sen. John Cornyn and was also a federal prosecutor in the U.S. Department of Justice's Public Integrity section in Washington, D.C.

Traylor was an Air Force pilot and instructor for 20 years and retired in 1991 as a lieutenant colonel. Traylor worked at the Pentagon, determining what classified access and weapons systems the United States' allies could obtain and also as a translator in Spanish.

Traylor later worked for Northwest Airlines and retired in 2007, and he has served at the U.S. Embassy in Ecuador as an Air Force representative.

The District 10 race was tighter in the Democratic primary. Cadien, who lives in Cypress, held on to an early lead, which slipped to around 52 percent late in the evening. With all precincts reporting, Cadien snagged 57 percent of the votes with 8,041 to her opponent William E. Miller Jr.'s 6,155 votes.

She spent the evening at the Harris County Democratic headquarters near her home before heading home to watch the final results come in.

Cadien is a registered nurse and has worked as a medical case manager for pregnant women as well as infants at Texas Health Steps and as a surgery supervisor for McGregor Medical Association.

In 2010, Cadien was elected as Precinct 26 chairwoman of Jefferson County. She is a public speaker for the Julie Rogers "Gift Of Life" program in which she brings awareness about breast, prostate and testicular cancers to a variety of organizations, including those targeting high school seniors.

She also holds an executive master's degree in public administration from Texas Southern University.
