OK why did Santorum win Shelby County? Aren't the Memphis suburbs full of rich Republicans?
In this part of the world, richers are frequently more likely to be religious nutters than poors. At least among white people (Republicans). And without precinct information, it's hard to tell who voted for whom. Northern Shelby County, for instance, is neither rich nor suburban. It may as well be its own rural county. And Santorum won with 37% countywide. Hardly a strong showing.
Santorum won the more middle/upper-middle class suburbs, Romney cleaned up in the wealthier and more cosmopolitan Poplar corridor.
