National: Hundreds of thousands of Americans cast a ballot without voting for a presidential candidate | The Washington Post
Nevada makes it simple. Voters in Nevada are given a choice for each race on the ballot: Candidate A, Candidate B or “none of the above,” a formal protest vote that is more or less popular depending on who candidates A and B are. In 2012, 5,770 Nevadans chose “none of the above” over Mitt Romney or President Obama, a total equaling 0.57 percent of all presidential votes cast. Obama won the state easily. In 2016, however, the results were more stark. More than 2.5 percent of the ballots cast for president in the state were “none of the above” — 28,863 in total in a race that Hillary Clinton won by 27,207. Enough protest votes to have swung the results of the election. There are protest votes in other states, too, of course; they just aren’t given space on the ballot. In most places these are called “undervotes,” ballots that are cast without a vote for the person at the top of the ticket.
