This is very much the case in Texas, and especially in Austin. Lots of people coming in from California, as well as a lot of tech companies moving here. Austin was already a very liberal city though, so it's not we're experiencing a cultural shift of any kind. Everything is getting very expensive, though it's mainly because property values are skyrocketing. It's a textbook example of what a liberal city is really like - gentrification of several low-income neighborhoods are driving the residents further away, and we now have one of the greatest levels of income disparity in the nation.
