The 2012 campaign is the third presidential contest Horsley has covered for NPR. He previously reported on Senator John McCain's White House bid in 2008 and Senator John Kerry's campaign in 2004. Thanks to this experience, Horsley has become an expert in the motel shampoo offerings of various battleground states.

Horsley took up the White House beat after serving as a San Diego-based business correspondent for NPR where he covered fast food, gasoline prices, and the California electricity crunch of 2000. He reported from the Pentagon during the early phases of the wars in Iraq and Afghanistan.

Before joining NPR in 2001, Horsley was a reporter for member station KPBS-FM, where he received numerous honors, including a Public Radio News Directors' award for coverage of the California energy crisis.

Earlier in his career, Horsley worked as a reporter for WUSF-FM in Tampa, Florida, and as a news writer and reporter for commercial radio stations in Boston and Concord, New Hampshire. Horsley began his professional career as a production assistant for NPR's Morning Edition.

Tovia Smith is an award-winning NPR News National Desk correspondent based in Boston.

For the last 25 years, Smith has been covering news around New England and beyond. She's reported extensively on the debate over gay marriage in Massachusetts and the sexual abuse scandal within the Catholic Church, including breaking the news of the Pope's secret meeting with survivors.

Smith has traveled to New Hampshire to report on seven consecutive Primary elections, to the Gulf Coast after the BP oil spill, and to Ground Zero in New York City after the September 11, 2001 attacks. She covered landmark court cases — from the trials of British au pair Louise Woodward, and abortion clinic gunman John Salvi, to the proceedings against shoe bomber Richard Reid.

Through the years, Smith has brought to air the distinct voices of Boston area residents, whether reacting to the capture of reputed Mob boss James "Whitey" Bulger, or mourning the death of U.S. Senator Ted Kennedy.

In all of her reporting, Smith aims to tell personal stories that evoke the emotion and issues of the day. She has filed countless stories on legal, social, and political controversies from the biggies like abortion to smaller-scale disputes over whether to require students to recite the Pledge of Allegiance in classrooms.

With reporting that always push past the polemics, Smith advances the debate with more thoughtful, and thought-provoking, nuanced arguments from both –or all— sides. She has produced award-winning broadcasts on everything from race relations in Boston, adoption and juvenile crime, and has filed several documentary-length reports, including an award-winning half-hour special on modern-day orphanages.

Smith took a leave of absence from NPR in 1998, to launch Here and Now, a daily news magazine produced by NPR Member Station WBUR in Boston. As co-host of the program, she conducted live daily interviews on issues ranging from the impeachment of President Bill Clinton to allegations of sexual abuse in Massachusetts prisons, as well as regular features on cooking and movies.

In 1996, Smith worked as a radio consultant and journalism instructor in Africa. She spent several months teaching and reporting in Ethiopia, Guinea, and Tunisia. Smith filed her first on-air stories as a reporter for local affiliate WBUR in Boston in 1987.

Throughout her career, Smith has won more than two dozen national journalism awards including the Casey Medal, the Unity Award, a Robert F. Kennedy Journalism Award Honorable Mention, Ohio State Award, Radio and Television News Directors Association Award, and numerous honors from the Corporation for Public Broadcasting, Public Radio News Directors Association, and the Associated Press.

She is a graduate of Tufts University, with a degree in international relations.
