In every metro area that I have lived in, several btw, there has always been
an underlclass made up of blacks and browns, among others.  Apparently, the
marxist notion of the bourgeoisie needing an excess labor force is a
universal requirement.  The suburbs are affected by their own need for cheap
labor so that the suburban-metro division is not necessarily race or class
based when it comes to elections.
The distinctions between Republican and Democrat cut across geographical,
class, and race boundaries.  It has more to do with the connections between
the military and business sectors which secure jobs and ideological
convictions!  The similarity between Repubs and Dems on most cultural issues
is obvious; the division happens when it comes to jobs!
