UNDATED - With his commanding victory in Nevada, Donald Trump has won 14 delegates in the state.

Marco Rubio won seven and Ted Cruz got six. John Kasich and Ben Carson each got one, with one delegate left to be allocated.

Overall, Trump has 81 delegates, and Cruz and Rubio have 17 apiece. Kasich has six delegates and Carson has four. It takes 1,237 delegates to win the Republican nomination for president.

Democratic presidential candidate Bernie Sanders is adamant that he is not giving up on South Carolina despite leaving the state to campaign elsewhere days before this early voting state's primary.

He says his campaign has closed the gap with Hillary Clinton and they are not writing off the state.

Sanders is beginning a multi-state campaign trip, returning to South Carolina just before primary voting Saturday.
