Does this map look familiar?

Have you seen this map before? Yes?

Actually it's the map of states where the Cosi Restaurant chain has stores. I don't know what it means, but I thought it must mean something. Amusing.

(from a private mailing list I am on)

[Note to those who don 't obsessively follow US Politics and culture: the map above looks a lot like the map showing U.S. states where the Democratic candidate for president won in blue and where the Republican candidate for president won in red. However the map actually shows where a certain sandwhich restaurant chain has stores. The relation between the two is a mystery to me too.]
