About 190,000 votes are still in the process of being counted in Nevada. State elections officials say two-thirds of the ballots were either returned by mail or dropped off in-person on Election Day. The majority of outstanding ballots are in heavily Democrat Clark County. Vice President Joe Biden maintains a lead over Pres. Trump in the Silver State. Nevada law requires all ballots postmarked on or before Election Day and received by close of business next Tuesday to be counted.
