Nevada's electoral votes in U.S. presidential elections 1864-2020

Nevada has participated in forty U.S. presidential elections since 1864, voting for the winning candidate on 32 occasions, which gives a success rate of 80 percent; in 2016, Nevada ultimately sided with the losing candidate, Hillary Clinton, after voting for the overall winner in the previous nine elections. Since 1864, Nevada has allocated all of its electoral votes to the Democratic Party's nominee on 19 occasions, and the Republican Party's nominee twenty times. The only time where Nevada did not vote for a major party nominee was in 1892, when it voted for the People's Party candidate, James B. Weaver (although one elector did could not vote in the 1864 election, as they were snowbound). In the 2020 election, the Democratic nominee, Joe Biden, won Nevada's popular vote by a margin of just 2.4 percent.

As of the 2020 election, no president or major party candidate has ever been from the Silver State. Nevada's allocation of electoral votes remained at just three for most of its history, however it has doubled to six since the 1980s, as the state's population has grown exponentially in the past half century. This population growth has been attributed to a large wave if internal migration in the U.S., particularly from the neighboring state of California.
