...Given the importance of geography in our politics, you’d expect political reporters and other commentators to be explaining why different regions vote in different ways. Unfortunately, you can watch many successive 24-hour cycles of political news coverage without getting any adequate analysis of political regionalism.

It’s not that America’s political commentators lack interest in demographic factors that influence politics. On the contrary, they are obsessed with a small number of demographic characteristics, chiefly race and sex. Viewers or readers are told endlessly about the gender gap and racial/ethnic differences in voting. But you would fall asleep waiting in vain for a political reporter on TV to explain differences between the Highland South and the coastal South or to describe the distinctive political culture of the states in the Midwest settled by New Englanders.

In the world of our political media, there are generic whites, generic Latinos and generic African-Americans from coast to coast. The categories are sometimes refined by class, but this still produces hopelessly vague descriptions — treating Italian-Americans in Rhode Island as though they are part of the same generic “white working class” to which many Scots-Irish Tennesseans and Norwegian-American North Dakotans also belong.
