US Democratic presidential candidate and former Secretary of State Hillary Clinton has won South Carolina primary over rival Senator Bernie Sanders by a massive margin, ahead of the crucial multi-state contests known as Super Tuesday.
"To South Carolina, to the volunteers at the heart of our campaign, to the supporters who power it: thank you," Clinton said in a tweet as the US media called the vote in her favor at the close of polls on Saturday night.
Clinton, with a 74-percent vote against Sanders's 25 percent, delivered her victory speech among huge cheers of supporters at the venue in Columbia, South Carolina.
"It's time, it's time, it's time for a woman in the White House," chanted Clinton’s supporters.
She has won three of four contests against Sanders, but South Carolina is her biggest win and support from black voters could carry over to Alabama, Texas, Georgia and a few other states voting on Super Tuesday.
Her victory speech was largely aimed at GOP frontrunner Donald Trump, mocking his slogan. “Despite what you hear, we don’t need to make America great again. America never stopped being great,” she said. “Instead of building walls, we need to be tearing down barriers.”
South Carolina was seen as a test of Clinton's strength with African American voters, who were expected to side with her over Sanders.
"More than a half a century after Rosa Parks sat, Dr. King marched and John Lewis bled, we have to invest in communities of color, reform our broken criminal justice and immigration system, we have to guarantee dignity opportunity and justice,” Clinton said.
In a statement, Sanders congratulated Clinton on her win but said the race was far from over. “This campaign is just beginning,” he said. “We won a decisive victory in New Hampshire. She won a decisive victory in South Carolina. Now it’s on to Super Tuesday.”
Sanders also slammed GOP frontrunner Donald Trump, saying, "when we come together, and don't let people like Donald Trump try to divide us, we can create an economy that works for all of us and not just the top 1 percent."
Clinton has solidified her status as the strong Democratic frontrunner to capture the party's nomination for the November 8 presidential election.
