Joe Biden won with 89.6% of the votes in the Democratic Party primaries in Nevada. The president of the United States won with almost 90%, according to partial results.
The Republican Party primaries, in which the "none of the candidates" option won, had a nod towards Donald Trump. Trump's name did not appear on the ballots, since he will be presented separately under the 'caucus' format this Thursday and, presumably, he will obtain the 26 delegates that are disputed in that state.
