Atlanta is a deep, intense blue, and its surrounding counties are a deep, intense red - a very visible artifact of white flight from the 60s and 70s.
That's the thing that seemed to stand out most. There and also in several spots like that scattered around the map. They look like a big zits that need to be popped.
You can pick out major cities, but there are also some surprises, like this medium depth band of blue that starts in Mississippi and runs through the heart of Alabama, Georgia, and South Carolina, culminating in Research Triangle in NC and VA. That, it seems, is (very roughly) the I-85 corridor, which has a plethora of two things: universities and military bases.
Linky, was kinda interesting.
