Dave Leip's Atlas of U.S. Presidential Elections

Data include candidates, political parties, popular and electoral vote totals, and voter turnout.

[1] A part of the website is the Atlas Forum, a debate and discussion chamber on U.S. and international elections and politics, as well as electoral mapmaking.

[8] PolitiFact has referred the website as "indispensable",[9] while The Washington Post has described it as "great-if-not-super-modern", and observed that "perhaps more interestingly, it lets us figure out which voters actually mattered — that is, the votes cast before and after a candidate clinched the nomination.

"[10] Leip's Atlas has been cited as a "preferred source for election results" by statistician and political pundit Nate Silver.

[11] The website has been cited or used a reference for U.S. election and political data by major media outlets including The Atlantic,[12] CBS News,[13][14] Men's Health,[15] Politico,[16] Roll Call,[17] U.S. News & World Report,[18] and The Wall Street Journal.
