Put differently, what would a map of the USA look like if all the secession movements in US history had succeeded? This beautiful map [*], created by Andrew Shears, a professor of geography at Mansfield University, provides one possible to answer to this question. Thanks to digg.com and Chris Cillizza of the Washington Post for this whimsical pointer.
[*] Note: The State of Colorado is still pretty much in one piece on this map because Professor Shears’ counterfactual map covers secession movements up to the end of 2011.
