The mid-Atlantic is bracing for a blizzard, but the 2016 campaign carries on regardless, and this Sunday on "Face the Nation," we'll bring you the latest, along with a new batch of poll numbers from Iowa, New Hampshire, and South Carolina in the latest CBS News Battleground Tracker.

We'll have the latest on the massive snow storm that's expected to paralyze much of the east coast this weekend.

Turning to politics, we'll talk with Republican presidential candidate Donald Trump, who's still riding high in the polls with just over one week before the Iowa caucuses. His rivals are sharpening their attacks, and Trump is responding in kind. Can the outspoken businessman who's been on top of the polls for most of the Republican primary season thus far stay on top when the voters actually begin to cast ballots?

We'll also talk with Democratic presidential candidate Sen. Bernie Sanders, I-Vermont, who's giving former Secretary of State Hillary Clinton some real competition for the Democratic nomination. But is he ready for the long slog of a primary process that could stretch out for months?

CBS News Elections Director Anthony Salvanto will be on hand to present new findings from the latest CBS News Battleground Tracker, looking at where the race stands in both parties in the early voting states of Iowa, New Hampshire and South Carolina. Who's up, who's down, and who's hanging by a thread? We'll let you know.

And to help us break it all down, we'll turn to an expert political panel, including the Daily Caller's Matt Lewis, author of "Too Dumb to Fail," Washington Post columnist Ruth Marcus, Washington Post reporter Ed O'Keefe, and CBS News Congressional Correspondent Nancy Cordes.
