Elizabeth Warren breaks out bat signal-like campaign sign as campaigns hustle on the eve of Nevada caucuses

Democratic 2020 hopefuls campaigned into the night on Friday on the eve of the Nevada caucuses.

The "first in the west" caucuses will begin at 10:00 a.m. local time on Saturday.

Almost 75,000 voters took advantage of the new early voting process, which allows voters to rank their top three candidates. Those results will then be sent to the voter's precinct, allowing them to participate in their local caucus.

That number is significant as only 84,000 Nevadans caucused in 2016.
