I was staggered by the results of this and the implication. Philadelphia is the most striking example, IMO.
There are still plenty of rural counties that vote Democratic, most notably in the South, granted these are probably ~98 percent majority African American, if I had to take a guess.
Republicans really haven't tried to make inroads within urban voters; if anything, they've just alienated them even more. Ted Cruz's "New York City values" smear is perhaps the most recent example. Republicans talk up a good game about how "exceptional" America is, lest they never stop bashing New York City, Los Angeles/Hollywood, San Francisco, and other big cities where they get crushed in every election. Las I checked, these cities were a part of America, too.
(Before I'm accused of being a hack, I'm fully aware that Democrats do the same to Rural America; most notably are Barack Obama's "bitter clingy" remarks in the 2008 primary, and John Murtha calling his former constituents in Southwest Pennsylvania rednecks.)
