How Did This Happen? In a sea of red counties, a belt of blue. How can we account for this string of counties voting so differently than their neighbors?

139-65 Million years ago: the Cretaceous Coastline in North America
The Answer: A Late Cretaceous sea coast from 139-65 Million Years Ago!
Sea Coasts produced very rich, fertile soil where the water meets the land. Millions of years later, this rich soil was highly sought after by farmers and plantation owners in the American South, where they forced African slaves to work the land.
A majority of the US felt pretty strongly that this type of forced labor was abhorrent; they fought a war over it (talk to your history teacher!). Following the Civil War, a large amount of these former slaves stayed in the areas in which they were previously enslaved: ie the American South.
Cotton Production (by Bale) in 1859. Cotton was a labor intensive crop to produce and involved a large amount of slave labor.
The Contemporary American political landscape reflects this post Civil War population: A direct result of the Cretaceous Sea Coast and the fertile soils it produced. The "Blue Bent" of Democrat voters is only fully understood thanks to paleogeography!
What about in Kansas? Has the Cretaceous Sealine affected the economy or politics here? Absolutely!
