Joe Biden, long considered the Democrats' frontrunner, finally won a state, as South Carolina was called for the former vice president the minute polls closed.
At Biden's headquarters in Columbia, South Carolina supporters screamed at the early call as MSNBC played on the jumbotron at South Carolina University's volleyball center. Directly after, the band playing the event started performing 'I Gotta Feeling' by the Black Eyes Peas.
Exit polls had signaled good news for Biden.
More than half of those who cast ballots were black, a stronghold for President Obama's vice president. Nearly half say that Rep. James Clyburn's endorsement - which was for Biden - was an important factor in their vote, according to the Washington Post.
And about half said they wanted the next president to return to Obama's policies, rather than dramatically shaking up the country, which is in line with what Biden's has proposed.
Biden has been trying to recover from his fourth place finish in Iowa and his fifth place loss in New Hampshire, as the Real Clear Politics polling average has Bernie Sanders nationally more than 10 points ahead of the former vice president.
South Carolina could finally give Joe Biden a win. The former vice president was photographed Saturday at a polling site in Greenville, as Democratic voters from the Palmetto State choose their primary pick

Pete Buttigieg looked to be in a battle for third place in the state. He held a town hall Friday night in Columbia that attracted just over 1,000 people and attended a canvass kick-off event in the capital city Saturday morning, before leaving to campaign in Super Tuesday states
Elizabeth Warren hoped to get some momentum from two memorable debate performances, where she went after billionaire candidate Mike Bloomberg, who is not competing in the South Carolina primary
One week ago, Biden had his best showing yet - second place in the Nevada caucuses, though he came in far behind Sanders. He earned about 20 per cent of the vote to Sanders' 47 per cent.
'Well, you all did it for me!' Biden told a crowd of supporters gathered at a union hall in Las Vegas. He spoke as NBC News was calling the caucuses for Sanders.
'Now we are going on to South Carolina to win and we're going to take this back,' Biden announced.
South Carolina could once again be a bump in the road for Sanders, who lost the first-in-the-south primary to Hillary Clinton four years ago by a whopping 47 points.
The final two polls taken in the state, released Friday, show Biden 21 and 9 points ahead. In both these surveys - one conducted by Trafalgar Group and one by Data for Progress, the Vermont senator is comfortably in second place.
The battle for third looks to be between Tom Steyer, a billionaire who funded the 'Need to Impeach' effort against President Trump and has never held elected office, or Pete Buttigieg, the 38-year-old openly gay former mayor of South Bend, Indiana.
The three women still in the race - Elizabeth Warren, Amy Klobuchar and Tulsi Gabbard - were all polling in the single digits in South Carolina Friday.
Warren had memorable debate performances in both Nevada and South Carolina, going after billionaire candidate Mike Bloomberg, who decided to skip the first four states, instead laying the groundwork for a 'Super Tuesday' delegate haul.
