Vote Vectors

The Rise and Fall of the Black Voter is a collection of maps documenting change in voting patterns throughout the 20th century (context). "It is an excellent companion to the purple maps of the most recent election, and a nice antidote to simplistic comparisons of pre-Civil War and recent electoral college maps. Republicans can bask in the glow of their successful 'Southern Strategy,' while Democrats can take heart that change, while often slow, is still possible." via Metafilter
