Oh it's definitely that, too. I mentioned driving through the wealthier neighborhoods and seeing all of the Biden signage. Some people I grew up with raised their kids in their beliefs, and then sent them to colleges or universities which only enforced what they grew up with. I think those kids and others are the target demographic for the developers trying to "re-vitalize" areas like downtown San Antonio. The people I speak with in El Paso have a mix of views but that's mostly because they have more exposure to the immigration aspect. The DFW metroplex is a mix of views but leans more left. Like Austin, it's a destination for job seekers.

My personal experience is interacting with people I know who have lived in the same house in the same city for 40+ years, and they suddenly have younger neighbors who moved here for the IT/white collar jobs but didn't leave (for example) their CA ideals in CA. The left leaning municipal governments have been steadily putting heavier financial burdens on the people with fixed incomes, and those people have been leaving the home they lived in for decades. Austin is the best example I've had personal experience with regarding property taxes forcing out fixed incomes. Austin government wants to be the next San Francisco, and they are well on their way to it: steadily increasing property taxes, rampant homelessness, infrastructure projects costing billions. Hopefully Texas can get a whole lot more conservative/patriot types to not just hold the ground (real estate and ideals) we have, but make some headway into the local governments.
