The Dallas Myth, Again quotes Molly Ivins:
There is a black Dallas, there is a Chicano Dallas, there is a Vietnamese Dallas, there is a gay Dallas, there is even a funky-Bohemian Dallas. But mostly there is North Dallas, a place so materialistic and Republican it makes your teeth hurt to contemplate it.
For the record, Dallas-proper, like all the major Texas cities, went for Obama this time around.
