Donald Trump has now won the South Carolina primary, according to the results that have come out:
This makes it Trump's second consecutive victory, and this along with the huge lead he's consistently maintained in the polls, has cemented his status as the clear frontrunner for the Republican Party nomination.
If he maintains this performance, then the only thing which could prevent him from becoming the Republican nominee might be a brokered convention arranged by party string-pullers, which Trump said he would not accept.
Meanwhile, Hillary Clinton has just defeated challenger Bernie Sanders in Nevada.
UPDATE: Jeb Bush has just dropped out of the US presidential race.
