South Carolina primaries: Vote seen as vital test for Biden

It remains to be seen if Biden can save his campaign by building on his relationship with African American voters.

Voters in the US state of South Carolina will soon decide which Democrat they think should challenge Donald Trump for the presidency.

This is seen as an important primary for former Vice President Joe Biden.

He’s enjoyed strong support among the state’s African American voters, but some of his rivals are closing the gap.
