Hillary Clinton is the projected winner in the South Carolina Democratic primary, according to multiple media outlets.

It appears that Black voters were a key factor in what's predicted to be a huge win for Clinton.

Initial exit polls show that Clinton won 84 percent of Black voters in South Carolina, carrying 86 percent of Black women. Clinton won Black voters younger than 30, but by a lesser margin, 57-43, according to ABC News.

The Clinton campaign, according to CNN's Dan Merica, is hoping for a 22-point win overall when the votes are all counted in South Carolina.

South Carolina marks the second straight contest won by Clinton, and her third win in the first four states to vote. It also affirms the notion that Clinton's support in the South — the so-called Southern "firewall" — will be one of the biggest hurdles for her opponent, Sen. Bernie Sanders. During the initial stages of the campaign when polling showed Sanders staying competitive in Iowa and winning New Hampshire, many predicted that the wave of Sanders' early success would fizzle when the campaigns headed to the South.

If the polling stays the same in the South, this prediction will prove true. Clinton has big leads in three states voting on Tuesday: Texas (26.3 points), Georgia (36.8 points), and Virginia (19.5 points), according to RealClearPolitics' polling average.

After outlets started calling the race for Clinton, Bettingodds.com moved Clinton to a 91.3 percent probability of winning the Democratic nomination.

What now for Bernie Sanders?

Sanders now heads to Super Tuesday looking to make a comeback. Unfortunately for Sanders, he has polling leads in just two states out of the 12 voting on Tuesday, according to RealClearPolitics — Massachusetts and his home state of Vermont. While Sanders claims a 75-point lead in Vermont, his lead in the poll average in Massachusetts is less than 1 percent, a razor thin margin.
