An Electoral Map

Chris Bowers in openleft.com has an interesting post in which he notes the presumptive Democratic presidential nominee

is relatively weak, for a Democrat, in the Mississippi Delta, Florida, and the northeast. To put it in Robert David Sullivan's ten political region terminology, Obama is relatively strong for a Democrat in Sagebrush, the Farm Belt, El Norte, and the Southern Lowlands, but relatively weak for a Democrat in Southern Comfort, Appalachia, the Northeast Corridor, and the Upper Coasts.

But the most intriguing part is his link to the post in boston.com by Mr. Sullivan in which the latter lays out these regions of the United States and his explanation as to the tendencies of each area to lean Democratic or Republican. Though the item is from January, 2004, it is worth more than a look.
