South Carolina primary live updates: NBC projects Biden wins

NBC News projects former Vice President Joe Biden has won the South Carolina primary with heavy support from black and moderate voters.

Saturday's first-in-the-South primary could be a pivotal moment for many of the candidates, especially Biden, who is counting on his projected landslide win here to reinvigorate his candidacy ahead of Super Tuesday.

Also on the ballot were Sens. Bernie Sanders of Vermont, Elizabeth Warren of Massachusetts and Amy Klobuchar of Minnesota, billionaire activist Tom Steyer and former South Bend, Indiana, Mayor Pete Buttigieg. Former New York City Mayor Mike Bloomberg was not in the running as he decided to skip the first four nominating contests.
