I remember being very angry after the first map came out and I found a way (I forget how, now) to reverse the colors.
I posted it here and said "There, that's better", but folks here seemed, at that time, to prefer us as red and them blue.
Basically, there are some very liberal/elitist areas like Jackson, Wyoming, Sun Vally, Idaho, the resort areas of Colorado, Hollywood, etc that go for the DNC. They are the ones who pull the strings there. Then you have your modern day reservations...the inner cities and their masses who are dependents of the DNC, who will vote for whomever will give them the handout and lartgess (just as our founders warned)...and thereby keep them dependent. They are true modern day "reservations", and like most of the carry-over Indian reservations...they go for the solicalist/marxist/elitist dems almost every time because they are utterly bought and paid for.
Most of the places where people work for a living, carry on a traditional life-style and have their roots firm in Christian faith...go for the GOP...at least from what one sees on the country wide county election map.
