Coming Up on "This Week": David Axelrod and Mike Huckabee

WASHINGTON, Jan. 6, 2012— -- This Sunday, George Stephanopoulos returns to the anchor chair on "This Week." Just hours after moderating the ABC News Republican Presidential Debate in New Hampshire with Diane Sawyer, and two days before Granite State voters head to the polls in the nation's first primary, George hosts a special edition of "This Week" live from Manchester, N.H.

After the GOP field faces off on Saturday night, how is the Obama campaign preparing to take on the eventual Republican nominee? Who do they see as their toughest opponent? Those questions for our headliner, top Obama campaign adviser David Axelrod.

And four years ago, Mike Huckabee rode to victory at the Iowa caucuses on a wave of support from Christian conservatives. On Sunday, George asks the former Arkansas governor and Fox News contributor for his take on whether Rick Santorum can ride a similar wave through New Hampshire and beyond. Can Mitt Romney get backing from evangelical voters? And will conservatives get a candidate they can embrace?

Then, George leads a powerhouse roundtable in New Hampshire, with ABC's George Will, Republican strategist Mary Matalin, ABC News political analyst Matthew Dowd, Democratic strategist Donna Brazile and ABC News senior White House correspondent Jake Tapper, as they dissect Saturday's debate. As all eyes look forward to Tuesday's primary, which candidate will move forward with the most momentum coming out of New Hampshire?

Plus, a look at your voice as ABC News senior political correspondent Jonathan Karl breaks down how the campaign is playing out on social media. See the whole picture, Sunday on "This Week with George Stephanopoulos."
