Democrats hope to keep up the dominant performance they showed on the first day of Nevada's two-week early voting period.
Fifty-five percent of Clark County voters who cast their ballots on Saturday were registered Democrats, while 27 percent were Republicans. Total Clark County turnout of 39,309 broke a 2012 record in raw numbers, but not as a percentage of the active registered voter base.
Democrats accounted for 51 percent of early voters Saturday in Washoe County, while 33 percent were Republican.
Democrats typically turn out at higher margins than Republicans in early voting, but Republicans need to ensure they narrow the gap so they don't lose tight races.
Democrats' celebrity-heavy push for early voting included a Sunday rally in North Las Vegas with President Barack Obama.
