BOLDUAN: Welcome back to a special holiday edition of AT THIS HOUR, everyone. This morning, the top Democratic presidential candidates are gathering in South Carolina. It's not only the first state in the south to vote, it is also a huge gathering in honor of Martin Luther King Jr Day. The presidential hopefuls rallying outside the state House after marching through the streets. And check your calendar. Today, you'll remember, marks one week until the first contest in the Democratic primary in Iowa. And the deadline pressure seems to be showing. Joining me now, CNN political correspondents, Jessica Dean and Ryan Nobles. Thank you, guys, for being here. Jessica, you're in Columbia, South Carolina, where these big events are taking place, have been this morning. What have you been hearing from the candidates and their message to South Carolina voters now?</s>JESSICA DEAN, CNN POLITICAL CORRESPONDENT: Well, really, Kate, their presence here is what has been so important to people here in South Carolina. This is a marquee event in an early state. As you mentioned, we saw them marching down the street together, the candidates kind of linking arms. And notably, Elizabeth Warren and Bernie Sanders standing side by side as they marched through the streets here in Columbia, South Carolina. It's interesting, a week ago, they were going back and forth with each other about that private conversation that they had. But today, the show of unity here in Columbia, South Carolina. And when it comes to South Carolina, former Vice President Joe Biden continues to lead here.
