Plus roundtable discussions on the economy, the GOP field and Iran tensions.

WASHINGTON, Oct. 13, 2011— -- With President Obama failing to get his jobs bill through Congress, is there anything he can do to turn the economy around before the 2012 election campaign?

And as the GOP field takes its final shape, the Obama campaign focuses its sights on frontrunner Mitt Romney. How will they take on the potential GOP challenger for the presidency?

Christiane Amanpour talks with top Obama campaign adviser David Axelrod in a "This Week" Sunday morning exclusive.

Then, as GOP contender Herman Cain surges in national polls, can he withstand scrutiny of his "9-9-9" economic plan? And can the White House and Congress come to any agreement on competing jobs proposals? The "This Week" roundtable with George Will, ABC News senior political correspondent Jonathan Karl, economist and former Clinton economic adviser Laura Tyson and Bloomberg Television's Margaret Brennan dissect the economic proposals from both sides of the aisle. And Republican strategist Mary Matalin and Washington Post columnist Ruth Marcus join the roundtable to discuss all the week's politics.

Plus, tensions have escalated between the United States and Iran after revelations of an alleged Iranian plot to assassinate a Saudi ambassador on American soil.

Mike Rogers, R-Mich., and The New York Times' David Sanger join Christiane to discuss the latest on the failed plot.
