From The Dish – “The Politics of Sprawl.”

.

Richard Florida compared “rankings of sprawling and compact development to voting patterns, as well as other significant economic and demographic variables” …

Our correlations suggest that sprawled America is Red America (Republican), while Blue America (Democrat) takes on a much more compact geography.  …  Researchers have identified a tipping point of roughly 800 people per square mile where counties shift from Red to Blue …

Princeton historian Kevin Kruse similarly explained this spatial link between a spread-out landscape and Republican political positions to the New Republic. “There are certain things in which the physical nature of a city, the fact the people are piled on top of each other, requires some notion of the public good,” he said. “Conservative ideology works beautifully in the suburbs, because it makes sense spatially.”
