Bernie Sanders has cemented his status as the Democratic front-runner to take on Donald Trump in November’s US presidential election.
He is projected to win Nevada’s caucuses, and early results suggest he is on course for a large victory.
So far, with 22% of the ballots counted in Nevada, Mr Sanders, the left-wing senator for Vermont, has 47% of the vote, ahead of Mr Biden on 23%. The field is then split between a number of other moderates, including Elizabeth Warren and Pete Buttigieg, who trail further behind.
There is a long way to go, however, until a nominee is confirmed.
Early results also suggest former vice-president Joe Biden has performed better in Nevada than in the other two states which have voted so far.
He had underwhelming results in Iowa and New Hampshire. Those states kicked off the four-month long primaries process, in which candidates are jostling to convince voters why they are the best candidate to challenge Mr Trump.
Candidates who have won more than 15% of the vote will be awarded delegates, who will then go to the party’s convention in July to support their Democratic candidate.
Before Saturday, Mr Sanders had 21 delegates, and while he will remain a long way off the 1,990 needed to become the nominee, victory in Nevada will bring him another small step closer towards that total.
Polls indicated Sanders has cut into that lead in South Carolina, and if the trend in Nevada holds in the Palmetto State, Sanders’ dominance could continue.
In addition, voting has already begun in the delegate-rich states of California, where Sanders campaigned Friday, and Texas, where Sanders was Saturday.
