I live in quiet, low-crime area outside of Austin . . . yes, it's the most liberal city in Texas, so much so that the rest of the state refers to it as "Moscow on the Colorado."
I don't envision any major problems regardless of the election's outcome, but any civil unrest would likely be confined to downtown, the entertainment district (Sixth Street, if you know the city) and around the University. Broken windows, trash cans set on fire, that sort of thing.
If it were to spill into the neighborhoods, well, this is still Texas, and rioting in a residential area to the degree that residents felt threatened would likely bring a response from some of the residents that the rioters would not appreciate . . .
Those that survived, at least.
