Everything You Need to Know About the South Carolina Democratic Primary

It's the Democrats' turn.

— COLUMBIA, S.C. -- Starting Sunday, you can kiss the early states goodbye.

According to polls, the race is all but a foregone conclusion: Clinton has maintained a dominating lead throughout the state campaign, and despite gains, Sanders could end up losing by a margin even more lopsided than his 22-point victory in New Hampshire. A Fox News poll released earlier this month showed Clinton leading Sanders 56-28 percent.

Still, the Palmetto State will see a number of story lines play out throughout the day -- several of which could have an impact on the crowded March calendar. Here’s your guide to all the action.

The Basics

Polls will be open statewide from 7 a.m. to 7 p.m. South Carolina holds an “open primary,” meaning any registered voter who didn’t participate in last week’s Republican primary may cast a ballot.

A Predictor of Things to Come?

Are These the Turnout Numbers of a Revolution?

Ballot boxes were stuffed to the gills in 2008, as voters turned up in record numbers in support of then-Senator Barack Obama. In a deep-red state, Democrats dwarfed their Republican counterparts, casting more than 530,000 votes. South Carolina Democratic Chairman Jaime Harrison doesn’t see that happening this year.

“I don’t think we’ll get there,” he told ABC News. “I think we’ll get about 400,000.”

He pointed to a larger field, which included high-voltage names like Clinton and Edwards, in addition to the potential for the first African-American president.

“The dynamic was so different,” he admitted.

Where’s Bernie?

Not here. As results trickle in Saturday, Sanders will be en route to a rally in Minnesota. Perhaps as a result of his fading hopes in the state, the Vermont senator has spent several days outside South Carolina this week, as he looks ahead to other contests.

Looking Ahead

It’s called “First in the South” for a reason. The lessons learned by each campaign will serve a valuable role in mapping out the rest of the March calendar, as one-state-at-a-time campaigning becomes a thing of the past.

Meanwhile, Sanders has his eye on Massachusetts, Minnesota, and even Oklahoma as potential wins. One state he shouldn’t have to worry about: his home state of Vermont, which looks like a slam dunk.
