Mitt Romney continued on the path to securing the Republican presidential nomination last night, winning all 37 delegates in Maryland, all 16 delegates in the District of Columbia, and at least 30 delegates in Wisconsin. In a speech after the results were tallied, Rick Santorum vowed to keep fighting. Wisconsin Public Radio's capitol reporter Shawn Johnson and The Takeaway Washington correspondent Todd Zwillich join us to look at the big picture from last night's results as well as a look at President Obama's own campaigning.

Have you ever looked at a stop light, a slice of pizza, or the hot air coming out of your hair dryer, and wondered: What and who went into making this? A new four-part PBS series called “America Revealed” delves into this question; scaling back from small everyday items to give viewers a big picture view of how America functions. Along the way, it doesn’t just unveil the secrets of how stuff is made; it also tells a story of America’s history and people. The series is hosted by Yul Kwon, an attorney, businessman, and technology expert, who you might also recognize as the 2006 winner of the reality show “Survivor.”

When she was only 15 years old, a girl in Washington state ran away from home. Within 36 hours, she was lured into the sex trade. And for over 100 days she was trafficked, with sites like backpage.com advertising her as an 18-year-old escort. Two years later, that girl is 17, and back at home. Her mother is working tirelessly, trying to prevent other children from living the same story as her daughter. Andrea Powell is the executive director of FAIR Girls, which seeks to prevent the exploitation of girls through empowerment and education. FAIR stands for free, aware, inspired and restored.

Today the United Nations will discuss happiness. Does happiness contribute to the well-being of the world? Tom Barefoot, co-coordinator of Gross National Happiness USA, believes that having a sound economy might be less important than having a country filled with happy people. How do we measure — or achieve — something so abstract?

The annual worst movie awards the Razzies gave all 10 prizes to Adam Sandlers "Jack and Jill". It's the first time in the 32-year history of the Razzies that a movie has won every category. Kristen Meizner, Takeaway Culture Producer and co-host of the Movie Date podcast, joins us to talk about the worst movie she's ever seen and what makes a bad movie... good.

Recent films "The Hunger Games" and "Bully" have faced struggles over how they should be rated by the Motion Picture Association of America. In the end, "The Hunger Games" received a PG-13 rating, while "Bully" received an R rating. But not everyone thinks these ratings make sense. David Long and his wife Tina Long appear in the film "Bully," in place of their son Tyler, who couldn't. After years of bullying, Tyler killed himself at the age of 17. Rafer Guzman is a film critic for Newsday and co-host of the Movie Date Podcast.

Yesterday, the House Judiciary immigration subcommittee held a meeting called "Holiday on ICE." Contrary to how it might sound, it had nothing to do with dancing elves or figure skating. In this case, ICE refers to Immigration and Customs Enforcement, the federal law enforcement agency under the department of Homeland Security that enforces immigration laws. Here to tell us about detention, past, present and future, is Doris Meissner, who served as Commissioner of the INS under President Clinton and Acting Commissioner under President Reagan. She is currently director of the U.S. Immigration Policy Program at the Migration Policy Institute.

Yesterday was the second of three days of hearings in the Supreme Court's review of Obama’s Affordable Care Act. The session was devoted to one key question: Is Congress overstepping its Constitutional power by requiring nearly all Americans to carry health insurance? Jeffrey Rosen is back to break it all down for us, and to give us a preview of what will happen in today’s third and final day of hearings. Rosen is professor of law at George Washington University, and he’s been following the arguments closely. He joins us from Washington, D.C.

The Supreme Court is hearing arguments on the Affordable Care Act Monday through Wednesday this week. But to your average, non-legal-scholar, the arguments can be hard to follow, and the specifics of the Act itself can very confusing. A lot of Takeaway listeners have been writing in with their questions about the Act. Todd Zwillich, the Takeaway’s Washington correspondent, is here to answer some of them.

Taxes, penalties, and tax penalties. That sums up much of what was discussed at yesterday's Supreme Court hearing on the 2010 health care overhaul bill, also known as the Affordable Care Act. Today's hearing, in which the court will focus on the constitutionality of the health overhaul, promises to be much more exciting. We speak with Jeffrey Rosen, professor of law at George Washington University, and Monica Haymond, a legal assistant originally from California who's been sleeping outside the Supreme Court Building since Friday night, hoping to get into today’s hearing.

From the first beats, Bruce Springsteen's “Born to Run” is captivating. The lyrics, the imagery, the aspiration.

In the day we sweat it out in the streets
of a runaway American dream
At night we ride through mansions of glory
in suicide machines

Tonight, Springsteen will perform in Boston. In honor of his visit, our production partner, WGBH Boston, is taking a closer look at “Born to Run” — and why it feels as relevant today as it did when it was penned nearly forty years ago.

Pope Benedict XVI arrives in Cuba today after a three-day visit to Mexico. It’s his first time visiting both countries. During his visit to the island nation, the Pope says he hopes to build on the dialogue and cooperation ushered in by his predecessor, John Paul II — whose visit in 1998 was considered groundbreaking. How do locals feel about the current Pope’s visit? And what, exactly, is the Pope’s desired outcome of the visit? Sarah Rainsford, Havana correspondent for our partner the BBC, joins us from Cuba.

The long-awaited 'The Hunger Games' is finally here! If you wanted to like the Twilight movies but thought Bella was kind of a wimp, this movie is for you. Protagonist Katniss Everdeen (Jennifer Lawrence) leads a cast of young adults through a fictional reality TV show in which children battle to the death. It's an awesome take on the teen movie genre, but is this sci-fi flick about homicidal adolescents a good date movie?

Listen to this week's podcast to find out what Rafer Guzman, film critic for Newsday, and Kristen Meinzer, culture producer for the Takeaway, think about this long-awaited and super-hyped blockbuster.

The big screen adaptation of the best-selling young adult novel the Hunger Games hits theaters this weekend. Our Movie Date podcasters Rafer Guzman and Kristen Meinzer are here to discuss the themes of gender and violence in the film.

Twenty-five years ago, in 1987, a novel called “The Bonfire of the Vanities” was published. Written by Tom Wolfe, the book touched on issues of class privilege, racism, greed, and politics, and came to define an era in New York City and in America. A quarter century later, the BBC is looking back on “The Bonfire of the Vanities” with journalist and personal finance expert Alvin Hall. How much has changed in New York in the years since it was published, and how much is the same?

Yesterday, President Obama kicked off a two-day tour to highlight his administration’s energy strategy, which includes a stop in a small city called Cushing. If you aren’t from Oklahoma, you might not know about Cushing, or why it factors into the president’s energy plans. Ben Allen, a reporter from affiliate station KOSU in Oklahoma City, is here to explain. Carol O’Dell owned a ranch just outside Cushing, and she’s still a regular visitor to the town.

All this week we’re talking about incarceration in America. Yesterday we looked at juvenile justice, and whether life-without-parole sentences for teenage murder convicts violates the Eighth Amendment's ban on cruel and unusual punishment. Today, we’re talking about super-maximum-security prisons and the effects of solitary confinement.

By now, most of us have heard of Trayvon Martin, the 17-year-old African-American boy who was shot and killed while walking through a friend’s gated community in Sanford, Florida. The shooter was George Zimmerman, a neighborhood watchman who is not black, and who thought Martin looked suspicious. Martin had no weapons on him — only a bag of Skittles and a can of iced tea.

On February 26th, Trayvon Martin, a 17-year-old black high school student was visiting his father in Sanford, Florida and watching the NBA All-Star game at a house in a gated community. At halftime, he walked to 7-Eleven to buy Skittles and Arizona Ice Tea. He was on his way back to the house when a neighborhood crime watch volunteer named George Zimmerman noticed him. Zimmerman was patrolling the neighborhood in his SUV. He called 911 to report "a real suspicious guy," and then took off after Martin. The details of what happened next are unclear, but other 911 calls from neighbors record screams for help and a gunshot. Martin was discovered dead with a bullet to his chest.

When a violent crime is committed and reported, it's expected that investigators will collect evidence, process it, and use that evidence to track down the perpetrator. But in tens of thousands of rape cases, that is not what happens. Instead, the evidence collected is shelved and left unprocessed for years. In many cases, the rape kits are stored incorrectly so that contamination is likely to occur. In other cases, the kits have even been deliberately destroyed by the police.

In places like Los Angeles and New York, efforts have been made to change this. And now Detroit and Houston are taking steps to do the same.
