CHARLESTON - US President Joe Biden cruised to victory in the South Carolina Democratic primary Saturday, vowing afterwards that he would make Republican rival Donald Trump a loser for a second time in November's election.
Democrats will now pore over the results to see how well the 81-year-old incumbent, battling low approval ratings, mobilised the voters who helped propel him to the White House four years ago against Trump.
Kicking off his march to his party's nomination, Biden secured a massive 96.4 percent of the votes in the first Democratic primary of the 2024 race, according to results with half the ballots tallied.
He swept past his only rivals on the ballot, self-help author Marianne Williamson, who won 2 percent, and Minnesota congressman Dean Phillips, who won 1.6 percent, US news organizations said.
As the results came in Biden was at a campaign event in California, as he turns his attention to the next steps in his fight for reelection.
"Now in 2024, the people of South Carolina have spoken again and I have no doubt that you have set us on the path to winning the presidency again -- and making Donald Trump a loser -- again," Biden said in a statement.
He urged people to get out and vote in November, saying the stakes for the United States could not be higher if Trump manages a sensational comeback to the Oval Office.
"The stakes in this election could not be higher. There are extreme and dangerous voices at work in the country — led by Donald Trump."
