Democratic presidential candidate Hillary Clinton has won the Nevada caucuses, but South Carolina voters have spoken, and the winner of Saturday’s South Carolina GOP primary is Donald Trump.

"There's nothing easy about running for president. It's tough, it's nasty, it's mean it's vicious, it's beautiful," said Trump.

Florida Sen. Marco Rubio has finished second, narrowly edging out Texas Sen. Ted Cruz by less than two-tenths of 1 percentage point. 

The results are unofficial, pending the state's formal confirmation of the outcome, which will take place by next Saturday.

DECISION 2016: Full Coverage of Presidential Race

Former Florida Gov. Jeb Bush suspended his campaign before the results were in, but he pulled ahead to nab fourth place in the primary, beating Ohio Gov. John Kasich. 

Trump leads the overall race for delegates with 55. Texas Senator Ted Cruz has 11 delegates, Marco Rubio has 10, John Kasich has five, and Ben Carson has three. To win the nomination a candidate needs 1,237 delegates.

SC Results (100 Percent Reporting):

  • Donald Trump – 32.5 percent
  • Marco Rubio – 22.5 percent
  • Ted Cruz – 22.3 percent
  • Jeb Bush – 7.8 percent
  • John Kasich – 7.6 percent
  • Ben Carson – 7.2 percent

Nevada Results (95 Percent Reporting):

  • Hillary Clinton - 52.7 percent
  • Bernie Sanders - 47.2 percent

Clinton now leads with 501 delegates after the Nevada caucus, while Sanders can claim 69, according to the AP.

However, the majority of Clinton's current delegate count comes from superdelegate endorsements. 

Superdelegates automatically attend the national convention and can support the candidate of their choice, regardless of whom primary voters back. They are party leaders -- members of Congress, party officials and members of the Democratic National Committee.

If these party insiders continue to back Clinton overwhelmingly -- and they can change their minds -- Sanders would have to win the remaining primaries by a landslide just to catch up. He would have to roll up big margins because every Democratic contest awards delegates in proportion to the vote, so even the loser can get some.

To win the democratic nomination a candidate needs 2,382 delegates.

-- Trump Says "It's Back to War" --

Trump congratulated his rivals on Saturday, especially Ted Cruz and Marco Rubio, as they battled for second place.

But despite the kind words, Trump says he goes "back to war tomorrow." He's predicting he will do "very, very well" in the next Republican contest in Nevada.

Trump predicts that as Jeb Bush and other Republican candidates drop out, many of their supporters will switch to his side.

-- Rubio Says He's One Step Closer to Being President --

Marco Rubio says the Republican presidential primary has become a three-person race between himself, Donald Trump and Ted Cruz.

The Florida senator is predicting that he will win the GOP nomination after performing well in the South Carolina primary. As results stream in, Rubio and Cruz are fighting for second place behind winner Trump.

Rubio is congratulating Trump for his victory in South Carolina's primary. He's also praising former Florida Gov. Jeb Bush, who dropped out after a disappointing finish in South Carolina.

Rubio is returning to his central campaign themes of a strong U.S. military and a new generation of conservatism. He said after South Carolina he's a step closer to being the next president.

-- Cruz Supporters Fight On --

Despite Ted Cruz's shortcoming in South Carolina's primary Saturday, his supporters are optimistic that he'll make a comeback in his home state of Texas and southern states with large evangelical populations.

Dean Johnson, a 55-year-old salesman from Sumter, South Carolina, says Cruz will "leave here with momentum."

Joe Bateman, who traveled from Illinois to help the campaign in South Carolina, says there's a "long road ahead" but he feels confident that Cruz will "blow away people's expectations."

Stacy Baker of Columbia, South Carolina says she really thinks Cruz can pull off a win if he keeps "doing what he's doing."

-- Bush Ends Bid --

A teary-eyed Bush on Saturday said he was proud of the campaign he ran to unify the country and advocate conservative solutions.

The son and brother of former presidents George H.W. Bush and George W. Bush entered the race to huge expectations in June, and quickly fueled them with fundraising.

But he quickly slid in the polls behind some of his more outspoken Republican rivals such as billionaire businessman Donald Trump and Texas Sen. Ted Cruz, who have billed themselves as anti-establishment alternatives to the early front-runner.

Following disappointing performances in both Iowa and New Hampshire, Bush pinned his hopes on South Carolina, a state where the Bush name has maintained some clout. But Bush was unable to break into the top three in South Carolina. He would likely have faced pressure from GOP leaders and donors to drop out had he stayed in the race.

-- Kasich Campaign Claims Victory --

John Kasich's campaign is already claiming victory in the so-called "governor's bracket."

Kasich's chief strategist John Weaver says in a statement that the race will now be a four-man contest between Kasich, Marco Rubio, Ted Cruz and Donald Trump.

-- Clinton Says There's More to Be Done --

Nevada's Democratic party's initial estimates are showing that 80,000 Democrats caucused on Saturday, about 10,000 more than most party insiders expected.

Still, it was well below the nearly 120,000 who showed up in 2008 for Hillary Clinton's contest against Barack Obama.

Clinton beat rival Bernie Sanders in the state's Democratic caucuses Saturday, earning her a second win in the nomination process.

With her husband, former President Bill Clinton, standing by her side, Hillary Clinton has told her supporters that "we're in this together."

"This is your campaign and it is a campaign to break down every barrier that holds you back," she said. "We're going to build ladders of opportunity in their place so every American can go as far as your hard work can take you."

Though she never mentioned Sanders by name, Clinton cast her rival as offering a narrow economic message that wouldn't tackle the full range of problems facing the country. Rattling off promises to lower student debt, reform the immigration system, combat systemic racism and improve education, Clinton promised a country of new opportunities.

"There's so much more to be done," she said. "The truth is we aren't a single issue country. We need more than a plan for the big banks."

-- Sanders Says He Beat Expectations --

Vermont Sen. Bernie Sanders says "the wind is at our backs" despite his loss to Hillary Clinton in the Nevada caucuses.

Sanders says Clinton ran a very aggressive and effective campaign in Nevada that led to her victory in the Democratic caucuses Saturday.

He congratulated her for her victory and praised her effort.

But Sanders is suggesting he beat expectations because he started far behind Clinton and gained significant ground.

Sanders said he's heading now to South Carolina and that he has an "excellent chance" to win many of the states voting on Super Tuesday.

Sanders said the election will result in one of the greatest political upsets in U.S. history.
