i have been thinking the same thing today. its really only a concentration of blue counties in states that make them blue. there are many other counties in those states that are red. i know here in nyc there is large amount of public assistance. there are also a lot of senior citizens. then you have plenty of blacks, jews and other minorities. there are also a lot of criminals. the weirdos in manhattan are hippies that are artistic or something else not dealing with reality.
i guess people living outside the cities should be thankful that they act like magnets for the undesirables in this country.
The rural areas are primarily homeowners. We feel the pinch when the gov't reaches into our pocket. Therefore, we desire a smaller, less intrusive gov't. The urban areas do not pay property taxes and usually get gov't handouts. They then tend to vote for the person who promises them everything. Its call redistribution of wealth or socialism.
