On 'This Week': Jon Huntsman and David Axelrod

WASHINGTON, Aug. 19, 2011— -- He served in the Obama administration but now he wants to bring it to an end. Sunday, in a "This Week" exclusive, Republican presidential candidate Jon Huntsman talks with ABC News Senior White House Correspondent Jake Tapper about his plan to win his party's nomination.

Behind in early polls, is he willing to take the gloves off and go on the offensive against Mitt Romney and Michele Bachmann? And will Rick Perry's entrance into the race create an opening or close the door on Huntsman's chances? The former Utah governor and U.S. Ambassador to China Jon Huntsman, only on "This Week."

Then, with more grim news on jobs and the economy, President Obama took to the road this week for a campaign-style bus tour. But with his approval ratings hitting all-time lows, can the president turn the economy around in time for his re-election campaign? Jake Tapper speaks with top Obama campaign adviser David Axelrod about the bumpy road to a second term.

Plus, the "This Week" roundtable with George Will, political strategist Donna Brazile, Jeff Zeleny of the New York Times, Republican pollster Frank Luntz, and Liz Claman of FOX Business Network size up the economic outlook and the 2012 field. And as the president begins his vacation, he might not be resting so easy as he gets flack from an unlikely place: his own base. That plus all the week's politics, Sunday on "This Week."
