The site has recently added state-level (and some county-level) data for the Presidential Elections of 1876, 1880, 1884, and 1888 to the database. The total figures for some states have changed slightly from the original html files due to differing figures between the primary sources referenced and the source used to create the original html tables (see What was the Real Popular Vote? entry for some additional information with regard to why popular vote figures for older elections are so variable.). Work continues to add data from older elections (state-level data, county-level data, county-boundary accuracy and image-mapping, etc.).
