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

About this resource

Dave Leip's Atlas of U.S. Presidential Elections is the work of a single individual. According to the author, it was started as a paper hobby after the 1992 Presidential Election. Dave Leip uses Excel as a tool to produce the pie charts and to help build the county-level maps.

There are two distinct elements:

  • The web site, which is free, and provides maps and data of elections at the national and state levels
  •  County-level data sets, which must be purchased, and come as Excel files.
    • UO Libraries has purchased county-level Turnout & Registration Data for the years 2000-2016. This is currently all that we have available.

Important note: Dave Leip's election maps use RED for the Democratic Party and BLUE for the Republican Party. See his FAQ for more information.
