Red
States and Blue States: History of Presidential Electoral Maps
The
use of color on maps is a key component in cartographic design. Perhaps the best known colors on a map are
the “red states” and “blue states” on a presidential electoral map.
According
to GeoLounge, the practice of
identifying a political party on a map by color dates back to 1883, when the
first map of red and blue political affiliations was produced. And since the 2000 election, the practice has
been standardized with red representing Republicans and blue representing
Democrats.
The
complete historical timeline of all 57 presidential elections can be tracked on
270 to Win. Metrocosm, a unique Web page for current maps
and statistical analysis, has created maps showing all of the colors of the
early presidential elections.
An
exhibit depicting the results of the presidential elections since 1952 is
currently displayed in the front windows of the GIS Research and Map Collection
(GRMC) on the second floor of Bracken Library.
Sixty Years of Red States and Blue
States will be on display through Election Day. And maps of the electoral results are
available for circulation from the GRMC.
