Sanders' New Hampshire victory may boost his bid for the party nomination, as the less-crowded field of candidates moves on to Nevada to convince voters they're each best positioned to beat President Donald Trump in November.
Speaking to supporters after the vote in New Hampshire, Sanders looked ahead to other key primary contests. "We're going to Nevada, we're going to South Carolina and we're going to win those states as well," Sanders said, touting his "unprecedented grassroots movement." Sanders also called for all Democrats to unite in the effort to defeat Trump.
