We recently added 2016 Senatorial and Gubernatorial results to our Election Maps collection. All of our election data come from Dave Leip's Atlas of U.S. Presidential Elections. In addition to winners and voter turnouts, the maps also include voting age population, citizens of voting age population, and competitiveness.
We also updated our system with the latest vote counts (including absentee and mail-in ballots) for the most up to date election result information.
