NORTH LAS VEGAS, NEVADA – OCTOBER 20: A Clark County election worker scans mail-in ballots at the Clark County Election Department on October 20, 2020 in North Las Vegas, Nevada. In-person early voting for the general election in the battleground state began on October 17 and continues through October 30. Earlier this year, Nevada Gov. Steve Sisolak signed a bill mandating that all registered voters in the state receive a mail-in ballot for the first time to help keep people safe from the coronavirus (COVID-19).
