Why are most of the cities on the list left-wing liberal cities?? Seems to be that all of them except maybe Raleigh, and possibly Denver, are infested with left-wing vermin. Surely, there must be some good Conservative places to go and live, where one can earn a good salary, and the prospects for the future are good.
Interesting observation. No left wing city can remain prosperous for very long. Eventually they run out of other people's money.
I think a lot of what gets labeled as "liberal" is more Libertarian. Austin is the prime example. We have state government and a major university that tilts it left, but many of the state Rats are moderates and some of what looks like the left are actually Libertarian entrepreneurs (like the Whole Foods CEO, John Mackey) versus Mark Cuban (fitting last name).
Also, the cities mentioned are most likely judged by the Metropolitan Statistical Area (MSAs) versus the city proper. The Dallas MSA includes Fort Worth (DFW), which has a good high tech manufacturing base (military) and is mainly conservative. Dallas is a patchwork of entitlement-addicted / gangster-cool pockets versus suburban soccer moms and professionals.
