On 'This Week': Mayor Rahm Emanuel and Sen. Kelly Ayotte

NEW YORK, JULY 13, 2012— -- Chicago mayor and former Obama White House chief of staff Rahm Emanuel, and Romney supporter and potential vice presidential nominee Sen. Kelly Ayotte, R-N.H., speak exclusively to George Stephanopoulos, Sunday on "This Week." Plus, James Carville and Mary Matalin join the "This Week" powerhouse roundtable.

The latest ABC News-Washington Post poll shows the presidential election in a dead heat, with President Obama and presumptive Republican nominee Mitt Romney tied 47-47. With less than ten percent of voters likely to change their mind before November, what will be the key factors to swing the few remaining undecided voters in key battleground states?

Will the latest charges about Romney's time at Bain and renewed pressure over releasing past tax returns hurt his campaign? Or will doubts about President Obama's handling of the economy move independent voters to Romney's side on Election Day?

Chicago Mayor Rahm Emanuel and New Hampshire Senator Kelly Ayotte weigh in on the 2012 election, only on "This Week" Sunday.

Then, the powerhouse roundtable debates all the week's politics, with ABC News' George Will; Democratic strategist James Carville, co-author of the new book "It's the Middle Class, Stupid!"; Republican strategist Mary Matalin; Democratic strategist and ABC News contributor Donna Brazile; and political strategist and ABC News political analyst Matthew Dowd.

With accusations of lying and secrecy flying between the campaigns this week over Bain, outsourcing, overseas accounts and tax returns, is the Romney campaign failing to fend off attacks and keep the conversation on the weak economic outlook?

How will President Obama's proposal to extend the Bush tax cuts for the middle class and end them for the wealthy impact the economic debate this fall? Did Romney win over any moderate voters by speaking to the NAACP, despite being booed? And as speculation heats up, when will Romney make his vice presidential selection?
