From NPR News, this is ALL THINGS CONSIDERED. I'm Audie Cornish.
MELISSA BLOCK, HOST:
And I'm Melissa Block.
In this hour of the program, we remember Christopher Stevens, the first sitting U.S. ambassador killed in more than 30 years. And we'll explore how the attacks in Libya and Egypt have become fodder for political debate.
We're going to hear more now about the film that was, at least in part, the catalyst for the violence in Libya, as well as protests in Egypt. Some news outlets are saying the filmmaker has gone into hiding.
As NPR's Elizabeth Blair reports, very few people have actually seen the supposed two-hour movie, if it exists at all.
It didn't take long for the attacks in Benghazi and Cairo to become part of the presidential campaign. Mitt Romney jumped in first. In a statement last night before Ambassador Stevens' death had been announced, Romney accused President Obama of sympathizing with those who waged the assault. The Obama campaign responded, saying it was shocked that Romney would launch a, quote, "political attack" at this moment. And the politics have continued today as NPR's Mara Liasson reports.
Every election season Republicans and Democrats tried to rally their base and to go after undecided voters. They're increasingly using the Internet in Get Out The Vote efforts.
NPR correspondent Shankar Vedantam, who reports on social science research, joins me now to talk about how Facebook could become a potent weapon in going after the biggest untapped voting bloc in the nation. Shankar, welcome.
SHANKAR VEDANTAM, BYLINE: Hi, Melissa.
BLOCK: Who are these mystery voters, this untapped voting bloc that we mentioned?
AUDIE CORNISH: Now a correction. Followed by your letters about we made you cry. Correction first. On Friday's program, in a story about Amazon's latest Kindle device, we said that Apple does not offer an iPad with a 4G wireless connection. In fact, some iPad models do include a 4G connection.
MELISSA BLOCK, HOST:
And now, on to those tears. They were shed over a connection of a different type.
