Rick Santorum headed in a different direction after his wins on Tuesday.
Here's NPR's Wade Goodwyn in Dallas.
WADE GOODWYN, BYLINE: North Texas was a good choice for former Pennsylvania Senator Rick Santorum to keep his campaign's momentum going. He met with evangelical pastors in the morning, Tea Partiers in the afternoon and a Republican women's group at night.

UNIDENTIFIED WOMAN: It is our pleasure to introduce to you Rick Santorum. Give him a Texas welcome.
Turn on the news on any given day, and you're likely to hear about the Dow Jones industrial average. It is the most frequently checked, and cited, proxy of U.S. economic health. But a lot of people — maybe most — don't even know what it is. It's just the stock prices of 30 big companies, summed up and roughly averaged. That's it.
And what does the daily movement of this number have to do with the lives of most Americans? Not much.
American lawmakers are furious about a mounting diplomatic crisis in Egypt, where dozens of nongovernmental workers, including 19 Americans, could face trial.
The United States says Egypt needs to let pro-democracy groups continue their work to help the country's transition, but Egypt accuses them of operating illegally.
The work of democracy promotion groups has raised suspicions in many countries, but Lorne Craner, who runs the International Republican Institute, says he has never seen anything like what's going on now in Egypt.
Labor unions plan to rally in front of the Arizona State Capitol on Thursday afternoon to protest four bills quickly moving through the state Legislature that could make last year's Wisconsin labor laws look modest by comparison.
Three of the four bills restrict the way unions collect dues and the way workers get paid for union activities. The fourth bans collective bargaining between governments and government workers: state and local. Unlike Wisconsin, it affects all government employees, including police and firefighters.
Stroll along a street in downtown Shanghai for very long, and you're likely to run into someone wearing Converse Chuck Taylor All Stars. One recent afternoon, Xu Jing was heading back from lunch to her job at an ad company in a pair of raspberry-colored Chuck Taylors.
"They have a young image, upbeat and outdoorsy, sporty," said Xu, 27, explaining the appeal. "Young people with an artistic sense prefer Converse."
Xu was accompanied by Chen Xiaolei, a co-worker who owns three pairs of Chuck Taylor high-tops.
Tai chi, the Chinese martial art involving slow and rhythmic movement, has been shown to benefit older people by maintaining balance and strength. Now, researchers have found that tai chi also helps patients who suffer from Parkinson's disease.
Leona Maricle was diagnosed with Parkinson's two years ago. At the time, she was teaching math, and she says she had experienced the telltale tremors of Parkinson's for a number of years. She learned how to cope.
You didn't have to look hard to see this one coming.
Catholics and GOP candidates have attacked the Obama administration's plans to require most employers — including religious hospitals and schools — to provide coverage of prescription contraceptives. Now the debate is moving to Capitol Hill.
Fresh off his hat trick in Minnesota, Colorado and Missouri, former Pennsylvania Sen. Rick Santorum campaigned in Texas on Wednesday, speaking to a group of pastors at Bella Donna Chapel in the town of McKinney.
Forty miles north of Dallas, where black prairie dirt meets the fresh poured concrete of suburbia, this is Rick Santorum country.
Here are two things you don't often hear mentioned in the same sentence: social media and nuclear weapons.
Rose Gottemoeller, acting undersecretary of state for arms control, quickly links those two unlikely partners in conversation. She's behind a campaign to discover how new communications tools can help rid the world of some of the dangers of nuclear weapons.
Crowdsourcing Nuclear Problems
Gottemoeller is an avid user of Twitter, and it made her wonder how Twitter and other methods of crowdsourcing a problem can help her in her work.
Down a quiet Beijing alleyway on a recent day, as the winter wind whistles, two men stand guard over a pile of bricks hidden behind a corrugated iron fence.
The pile of rubble was once the home of the man known as the father of modern Chinese architecture, Liang Sicheng. The Orwellian reason for its demolition? "For maintenance," according to a Xinhua news agency report, citing the developer, Fuheng Real Estate company.
