Austin's a state capital. State capitals are always more "liberal" than the state, in general. Not unlike Boston or Sacramento or Nashville. (yes, I know there are counterexamples: Tallahassee comes to mind.) State capitals have several important features in common: 1. because the workforce depends heavily on government/education and socialized resources, they tend to be big government types. 2. also because of this effect, state capitals tend to weather economic downturns better than the rest of the state. 3. because capitals bring together people from diverse and far-away places (both ideologically and geographically), people who live in state capital cities get used to strangers and strange ideas quickly. And a state capital like Sacramento or Austin would have that phenomenon more than most, since they are the capitals of the most- and second most-populous states, respectively. They are also, respectively, the state capitals of the 3rd-largest and 2nd-largest states geographically.
