If you haven’t registered to vote yet, you still can. Nevada is one of 20 states that allow residents to register and vote on Election Day. “All you need to do is bring your ID with you to the polls,” according to Debra Cleaver with VoteAmerica. A polling worker will help you fill out a voter registration form, then you get to vote. There are significant numbers of Americans who aren’t registered who can still cast a ballot on Election Day.”
