In recent months, CBS News has made a concerted effort to focus more heavily on hard news, shifting the focus of its morning and evening news broadcasts.
"[CBS News Chairman] Jeff Fager and [CBS News President] David Rhodes have really tried to bring back CBS to do what CBS does best, Schieffer said. "What we've always done best is when we concentrated on the news and the hard news."
Fager and Rhodes made a promise to Schieffer, the Sunday show host says. "They said to me, 'If you can get your numbers up, just a little more than where they are now, we can talk about this, we think this is doable; damned if they aren't men of their word."
The GOP presidential debates have helped Face the Nation's ratings. And the program has regularly featured 2012 presidential candidates.
"We'll have more guests. We'll spend more time with roundtables," Schieffer said, adding that CBS political director John Dickerson, O'Donnell and the New York Times' David Sanger are expected to be roundtable regulars on the revamped one hour program. The show will also feature more on-location reporting.
"We made a decision at the beginning of this race. We were just going to cover this campaign," Schieffer said. "We think these programs are about American politics. With the campaign coming on we saw that as our number one story. It really had to be a big story to move us off that."
Face the Nation will continue to cover non-political breaking news events like the earthquake in Japan and the uprising in Egypt, but Schieffer cautioned, "We're about American politics. If you want to find out what's going on in American politics, this is where you'd go. ... We're not going to get off on any esoteric topics. We just stick to the meat and potatoes topics."
