Migrants bring new ideas so a certain amount of discomfort and change is expected. But judgements and assumptions need to be discussed to work out if there is any merit to them. There is a risk there that shouldn't be glibly ignored.
So I suppose I'd call on you to flesh that out with some alternatives that fit the facts or some challenges to the assumptions rather than just calling a spade a spade. We all know it is a spade. If the spade is inappropriate suggest a better tool instead.
Aside from a few state/city couplings(Omaha, NE comes to mind) a US "State" is a poor indicator of differentiated policy or ideology. People in Atlanta or Miami or LA or Seattle have a lot more in common with each other than some might think.
Moreover, it seems like you're attempting to paint the picture that a typically Democratic State is somehow worse off than a conservative one. I'm positive that a person born in Washington or California almost always has a better statistical and economic outcome than someone born in the Deep South, for example. So, it seems if I were correct(and I'm almost certain I am), the spade is doing something right.
(please do not assume any of the following takes a stance on these issues. Also don't imagine I know what I'm talking about)
On gun control, rural areas can have more than one gun per person with virtually no impact on an already negligible violent crime rate, while urban areas have fewer guns that are all much more likely to be involved in a homicide. So rural people see the issue as taking away rights for no benefit and urban people see that resistance as tacit support of gun violence and an attack on human life.
On abortion, cities have a lot more opportunity for promiscuity and have more unwanted pregnancies as a result. In the country, abortions are a much rarer concern; eliminating them would have little impact and resistance seems like tacit support of an attack on human life.
On taxation, city wages are higher. This may, citation needed, also influence positions on immigration.
Pollution is a greater concern in the city. Law enforcement corruption is a greater concern in the city. Cost-of-living and therefore necessary minimum wage are higher in the city.
I could go on (I can't, but fun to say so anyway).
Texas and Florida are two of the states that are experiencing meteoric growth and to imply that those moving in are not shifting the political climate to that in which they came from is to ignore the fact that both went from solidly conservative states, with conservative large metros. To toss up states where the metros became in flux. To ignore that those moving in are not voting in the same failed policies that they are fleeing ignores the fact that both states policies are in fact starting to trend towards taxation, lowering of property rights and large scale social programs. The spade is a spade.
The same happened to Denver over the past 20 or so year.
On a note related to the main topic, I live in FL in the Florida Keys, it is a paradise I spearfish on the weekends and am usually out on a boat. Prices have gone up here, but one can still purchase a home on the water for under 500k. I could barely get a decent apartment in the valley for what I paid for my 7 acres of oceanfront land and home. I mention this to make the point that I can certainly see the draw, you get so much more for your money if one sells out of a major CA metro and moves to one of the growth states.
Meanwhile, blue states have a "worst of both worlds" kind of policy. They don't permit much sprawl, and also don't permit much density, thereby pushing people to states where they do permit sprawl. Then they tell you that this is good for the environment, somehow.
That said, while it makes for cheap single family homes, sprawl has a LOT of negatives. Strong Towns explains how it basically functions like a Ponzi scheme in the long term, and within older cities the sprawlier parts are usually subsidized by the denser ones. There's also more cost to the environment, to health, to noise, to safety, and for transportation costs for both the government and the user. There's a reason the US has an unusually high traffic fatality rate per 100k people for a developed country, and there's an impact on our collective national waistline as well.
Texas really wants a tech industry, which is why it is importing lots of liberals. By that I mean these people don’t move to Texas to be in Texas, rather they were lured their by great job opportunities.
This is incorrect.
This observation may actually indicate the opposite, it is conservative policies that are failing. To see this, consider two potential reasons why people move away from urbanized progressive areas into more conservative areas:
1. Progressive policy failures (as you suggest)
2. The conservative areas are under-developed, and therefore have a greater potential for growth, which creates incentives to move there.
Under the first hypothesis, liberal policies ruin things. But under the second hypothesis, conservative policies ruin things. There is a pretty simple way to test out which is true: if the first is true, and progressive policies are at fault, then a conservative area would become more conservative as it becomes more popular and more people move there. If the second is true, then conservative areas would become more liberal as it becomes more developed.
Pretty much every originally conservative area that becomes developed later becomes more liberal (hello Texas). It's pretty clear that your hypothesis is false.
People who have worked in California until retirement taking advantage of it's strong economy to secure retirement income and then moving elsewhere to further maximize retirement dollars are a big part of the trend; to the extent that's about policy outcomes, it's policy success.
For California, it's mostly having a very successful economy combined with terribly stupid housing policy.
Conservative areas are 'better' on the latter on some level because they permit more sprawl, which does provide for more supply, which means lower housing prices. Car-dominant sprawl is a disaster in other ways, though: environment, pollution, health, noise, danger, cost to government, cost to user, etc.
And conservative areas are usually even worse at allowing density, despite being ostensibly free market. I have a lot of conservative FB friends, and it's always amazing how quickly they're suddenly in favor of strict government regulation when it's for keeping housing density low; when it's their favored lifestyle at risk, free market principles are apparently no longer an issue.
