This Sunday on “State of the Union” – Candy is on the road again, live from Manchester New Hampshire to preview Tuesday’s New Hampshire primary. The polls show Mitt Romney with a sizeable lead, but it’s Jon Huntsman who has pounding the pavement and shaking hands in the Granite state, logging more days and events than any other GOP candidate. Will his bet on New Hampshire pay off, and how well does he need to finish to continue his campaign? We’ll ask him.

Also, Newt goes negative, hitting Mitt Romney hard on what Gingrich calls his “moderate” stances. We’ll parse the attacks and Saturday night’s debate with Romney surrogate and former New Hampshire Governor John Sununu, and Gingrich adviser former congressman Bob Walker.

Then, House Democratic Leader Nancy Pelosi sits down with Candy for an exclusive interview. She talks about President Obama’s anti-Congress message as well as the GOP presidential candidates.

And we end the show with our reporter panel: Neil King of the Wall Street Journal and Phil Rucker of the Washington Post.
