City Slickers: The growth of urbanized areas could shift some states from red to blue over time?

The National Journal reports:

In political vernacular, “urban” issues have long been code for policies of primary concern to minorities. In coming decades, that stereotype will start to look outdated as Americans of increasing diversity move to the nation’s big cities.

That migration is affecting our politics. Census data from 2010 show Democrats are much more likely to collect electoral-college votes from the most urbanized states. At the same time, the states with the fastest-growing urbanized areas are now more likely to vote Republican. Taken together, the data suggest the growth of urbanized areas across the nation could put more Republican-dominated states in play in the long run.
