"Some years ago David Wasserman, an analyst with the Cook Political Report, spotted a way to predict the political leanings of any given county: check whether it is home to a Whole Foods supermarket, purveyor of heirloom tomatoes and gluten-free dog biscuits to the Subaru-owning classes; or to a Cracker Barrel Old Country Store, a restaurant chain that offers chicken and dumplings and other comfort foods to mostly rural, often southern customers. Mr Trump won 76% of Cracker Barrel counties and 22% of Whole Foods counties, the Cook Political Report calculates. That 54 percentage-point gap is the widest ever: when George W. Bush was elected in 2000 it was 31 points. Eight years later when Barack Obama took office, it was 43."
