It's been widely noted that Barack Obama's winning coalition drew up the wide ethnic, racial, gender, and sexual orientation diversity of a new and rising America, while Mitt Romney and the GOP captured the wide majority of white men. In their 2004 book The Emerging Democratic Majority, John Judis and Ruy Teixeira describe this new majority based on diverse ethnic and racial voting blocs and knowledge workers in urban "ideopolises."
The underlying "drivers" of American voting patterns, writes Troy, are "density and diversity" — both of which are found in larger, more populated cities and their constituent counties.
