What's the best way for Mitt Romney to stop Rick Santorum?

For the answer, we went to someone who has done it before.

Democratic strategist Saul Shorr helped Bob Casey defeat then-Sen. Santorum, R-Pa., in a landslide in 2006. Santorum lost by 18 points.

But Shorr says that was a general election; in a Republican primary, Romney will have a much harder job.

It's a new kind of brinksmanship for U.S. doctors: caring for patients with life-threatening diseases when the supply of critical drugs threatens to disappear.

Mexican Federal Police, some of them covered head to toe in white hazardous-materials suits, paraded Jaime Herrera Herrera in front of the media in handcuffs this week. Officials say he was the methamphetamine mastermind for Mexico's most wanted man, Joaquin "El Chapo" Guzman, who runs the powerful Sinaloa cartel.

For older Americans looking for work, finding a job can be a tremendous challenge. Someone 55 or older will typically take three months longer to find employment than the average job seeker.

And with more people of all ages looking for work in the slow economy, age discrimination complaints are on the rise — but becoming harder to win.

Employment law experts say that has a lot to do with one particular case: Gross v. FBL Financial Services Inc.

Audits of working conditions are under way at Foxconn's manufacturing plants in China, a key link in Apple's supply chain of iPhones, iPads and other devices. The effort will include visits to at least three sites, "each with more than 100,000 workers," says Auret Van Heerden, president of the Fair Labor Association.

"So we've taken a representative sample of over 35,000 workers," Van Heerden tells All Things Considered co-host Robert Siegel, in an interview airing Wednesday.
