Sunday on Face the Nation: Lugar, presidential roundtable

Religion and Politics on FTN
Bob Schieffer previews Sunday's Face the Nation with Cardinal Dolan and others on religion and politics in America.

The race is on, and it's a close one. Polls out this week have President Barack Obama narrowly edging out presumptive GOP nominee Mitt Romney in key battleground states, but there's a long five months ahead still - at this point, do polls really mean anything? How effective have the Obama camp's attacks on Mitt Romney's record at Bain Capital been? And, how is Romney pushing back? We'll talk to Obama Senior Campaign Adviser Robert Gibbs and Romney Campaign Senior Adviser Ed Gillespie about all the latest on the campaign trail.

Also, we'll hear from six-term Senator Richard Lugar, R-Ind., who lost a primary race to Tea Party-backed candidate Richard Mourdock. In his concession statement, Lugar wrote "Mourdock has pledged his support to groups whose prime mission is to cleanse the Republican party of those who stray from orthodoxy as they see it." He said this attitude is present in an "increasing number of legislators in both parties... is not conducive to problem solving and governance." Does he think Congress is capable of doing anything this election year? What will it take to undo the gridlock Washington seems to be tangled up in?

Then, we'll look at the role of the presidency in history. We'll talk to Robert Merry, former editor of Congressional Quarterly, now editor of the National Interest. He's got a new book coming out titled, Where they Stand: The American presidents in the eyes of voters and historians. Plus, Time Magazine editors Nancy Gibbs and Michael Duffy, co-authors of The President's Club will be here. And we'll get CBS News Contributor and Presidential Historian Douglas Brinkley's take on all the presidents, past, current and future. Brinkley has his own new book out, Cronkite. It's all about Walter Cronkite - and the Presidents he covered as a reporter and anchor for CBS.
