In Nevada, there is an option on the ballot that allows you to vote for "none of these candidates." And that option won Tuesday's Democratic primary for Governor. From Politico:
“None of these candidates” earned 30 percent of the vote when The Associated Press called the race, outpacing the leading actual candidate, Robert Goodman, a retired state Economic Development commissioner from Las Vegas who’s run statewide twice before and shares a last name with the Vegas mayoral dynasty, at 25 percent. Nevada Democratic leaders acknowledged earlier this year that they had failed to recruit a credible candidate to face GOP Gov. Brian Sandoval in the fall. And on Tuesday, Silver State Democratic primary voters agreed, casting more votes for the state’s quirky “none of these candidates” option than any one of the eight actual humans on the ballot.
The second place finisher, Robert Goodman, who lost to "none of these candidates" will face GOP Governor Brian Sandoval in November.
